AB  - Alterations in gut microbiota and deregulation
of the gut immune system are recognized
as important events in autoimmune diseases.
The knowledge about the important role of anaerobic
gut bacteria that produce short-chain
fatty acids (SCFAs), in the regulation of intestinal
barrier and immune response made a way
for the development of microbiota-based interventions.
Our research aimed to isolate the
strains with the potential to produce SCFAs,
from healthy volunteer fecal material, and to
test their effects on IL-8 production in the culture
of intestinal epithelial cells (Caco2) as an in
vitro system imitating initial intestinal inflammation,
the effects on the expression of neuronal
activity-regulated genes of Caenorhabditis
elegans, and the effect on the development
of experimental autoimmune encephalomyelitis
(EAE), a mouse model of multiple  sclerosis.
Three isolated butyric acid (BA)-producing
strains, and three acetic acid (AA)-producing
strains diminished the production of IL-8 in Caco-
2 cells treated with IL-1β/TNF-α. Further, all
BA-producing strains stimulated the expression
of important neuro-related genes in C. elegans.
Based on the strongest effects in these
assays an isolate identified as Faecalimonas sp.
NGB245 strain was further tested in EAE model.
The oral treatment of EAE-induced mice with
this strain for 16h per day for 15 days resulted
in alleviated daily clinical scores, maximal
clinical scores, and the duration of the illness
in comparison to the effect of media used for
strain cultivation. These results point to the potential
of NGB245 to modify the gut-brain axis
opening the field for future development of microbiota-
based therapy for the diseases associated
with immune response dysfunctions.

AB  - Autoaggregation, the ability to self-aggregate,
is widespread among both Gram-positive and
Gram-negative bacteria. The functional role
of aggregation is not fully understood, but it
is believed to be involved in the adaptation of
bacteria to environmental conditions (PMID:
31294207). One interesting class of compounds
responsible for the aggregation of lactic
acid bacteria is aggregation factors—surface
high-molecular-weight proteins rich in threonine
and lysine (PMID: 30027759). Recently,
our research group discovered a new strain of
Streptococcus thermophilus in the mountainous
regions of Serbia, exhibiting an aggregation
phenotype. Aggregation phenotype was confirmed
visually and using microscopy. Complete
genome of Agg+ strain was sequenced using
NGS and a gene encoding a potential aggregation
factor, which was named aggS was identified.
The predicted threonine (12.5%) and lysine
(10.5%) rich protein contains 2367 amino acids,
with an average molecular weight of 255986.63
Da. AggS also contains two cysteine residues,whereas previously well-described aggregation
factors of this type did not contain any cysteine
residues. The predicted protein includes an
N-terminal YSIRK-like signal sequence and an
LPXTG cell wall anchor domain. It has 6 Mucin
binding domain repeats alternating with 6 Mub
B2-like domain repeats. Additionally, we found a
region resembling an ice-binding domain. Given
that these bacteria endure prolonged periods of
low temperatures, it can be speculated that this
surface membrane protein also helps the bacteria
withstand freezing. The fact that the alignment
using BLASTp revealed AggS to be most
closely related to an uncharacterised protein
from the genome of Lactococcus garvieae, along
with the discovery of a transposase gene sequence
upstream of the gene, suggests that the
aggregation factor was likely acquired through
horizontal gene transfer. We plan to clone it into
a shuttle vector and investigate the aggregation
phenotype using a heterologous expression system
in Lactococcus lactis, as well as explore its
other functions.

AB  - There has been an epidemic of various non-communicable
degenerative and autoimmune diseases,
strongly associated with the modern
lifestyle. Among them, neurodegenerative and
psychiatric disorders represent a huge burden on
society. Recently, all these diseases have been associated
with the gut microbiota dysbiosis. Gut
microbiota-host interaction research has been
greatly improved due to development of molecular
high-throughput techniques based on
various ‘omics’ techniques coupled with bioinformatics
and data science developments. However,
the mechanisms of the host–microbiota crosstalk
are still poorly understood. The NextGenBiotics
project proposes an innovative integrative
multi-omics research strategy for deciphering
the mechanism behind the cross-talk among
microbiota and gut-brain-axis. The 118 novel
NGPs candidates belonging to Dorea sp., Blautia
sp., Bacteroides sp., Roseburia sp., Sellimonas
sp., Faecalicatena sp., Phascolarctobacterium faecium,
and Faecalimonas sp. were cultivated. The
25 NGPs with confirmed safe status and potential
probiotic potential were screened in C. elegans
model for their effects on behavioural and neuronal
activity. The most prominent candidates
with ability to upregulate expression of genes
involved in neurotransmiting are further tested
in EAE (an animal model for MS) and CUMS depression
model. The specific microbiota-derived
metabolites have been identified as potential
neuro- and psycho-biotics. The NextGenBiotics is
highly ambitious project, dedicated to pioneering
work in the field of multi-omics studies related
to the cultivation of novel anaerobic NGPs
and the studying of their effect on MGBA. This
concept enabled studying bidirectional communication
between gut microbiota and brain
on the functional level that will significantly
contribute to the growing body data related to
MGBA. The results obtained during NextGenBiotics
determined the genes/metabolites and the
associated mechanisms involved in health-promoting
effects of NGPs in MGBA beyond stateof-
the-art, broadening the scientific knowledge
and opening up the possible novel therapeutic
approaches in prevention and therapy of neurodegenerative

AB  - Psychobiotics are live bacterial strains impacting the central nervous system, producing
neuroactive substances like GABA. GABA from
microbiota influences neural signals, affecting
neurological parameters, sleep, appetite, mood,
and cognition, traversing the intestinal barrier to bind to receptors on enteric neurons and
the vagus nerve. Lactobacillus and Bifidobacterium species can synthesize GABA from dietary
glutamate, with Lactobacillus rhamnosus shown
to reduce anxiety and depressive behavior, elevating hippocampal GABA. Limited knowledge
exists about anaerobic GABA producers, warranting further research for a comprehensive
understanding. Material for isolation comprised
fecal samples from healthy donors, with isolation conducted in an anaerobic chamber within
a maximum of 1 hour after sampling. Isolated
bacteria were identified through sequencing
the 16S rRNA gene. For bacterial cultivation, different types of media were used. PYG medium
contains hematine and vitamin K, essential supplements for the cultivation of anaerobic bacteria. All media included 0.1% L-cysteine, playing a
role in oxygen reduction, and 0.5% glutamate, a
precursor for GABA production. After identification, the presence of GABA in 8 tested bacterial
species was determined using the TLC method.
Quantification of GABA was performed using the
HPLC method. Furthermore, the positive effects
observed in Caco2 cells with induced inflammation, after treatment with certain anaerobic postbiotics producing GABA, indicate the potential
anti-inflammatory effects of these postbiotics.
The study implies anti-inflammatory effects of
anaerobic GABA producers, offering insights into the complex interplay among gut microbiota,
immune function, and mental health. Recognizing inflammation’s role in depressive symptoms,
targeting anaerobic bacteria involved in GABA
synthesis could modulate neurotransmitters and
inflammatory responses, presenting a comprehensive approach to mental well-being. Advancing research in this area contributes to a holistic
understanding of anaerobic bacteria, GABA production, gut microbiota, and mental health. This
offers avenues for novel therapeutic approaches
and enhances overall quality of life.

AB  - One of the major genera of the lactic acid bacteria family, Enterococcus sp., has a controversial status, reflected in the fact that enterococci are utilized as starter cultures and probiotics, in addition to being known to cause nosocomial infections. The qualified presumption of the safety list and the widely acknowledged safe status for Enterococcus species are absent. Rich sources of Enterococcus faecium species with possible probiotic characteristics can be found in artisanal dairy products, typically made from raw milk. To further understand the probiotic potential and health-promoting effects, this study looked at the presence of virulence factors and adhesion properties of En. faecium isolated from artisanal dairy products from Western Balkan countries.

AB  - This study aimed to explore the probiogenomic characteristics of artisanal bacteriocin-producing Enterococcus faecium BGZLM1-5 and its potential application in reducing Listeria monocytogenes in a milk model. The BGZLM1-5 strain was isolated from raw cow’s milk from households in the Zlatar Mountain region. The whole genome sequencing approach and bioinformatics analyses reveal that the strain BGZLM1-5 is non-pathogenic to humans. Bacteriocin-containing supernatant was thermally stable and antimicrobial activity retained 75% of the initial activity compared with that of the control after treatment at 90 °C for 30 min. Antimicrobial activity maintained relative stability at pH 3–11 and retained 62.5% of the initial activity compared with that of the control after treatment at pH 1, 2, and 12. The highest activity of the partially purified bacteriocin was obtained after precipitation at 40% saturation with ammonium sulfate and further purification by mixing with chloroform. Applying 3% and 5% (v/v) of the bacteriocin-containing supernatant and 0.5% (v/v) of the partially purified bacteriocin decreased the viable number of L. monocytogenes ATCC19111 after three days of milk storage by 23.5%, 63.5%, and 58.9%, respectively.

AB  - Introduction: Gut-brain axis has been identified as an important target for prevention of neurodegenerative and psychiatric disease. To date, specific microbial strains resident in the intestinal ecosystem
have been described to modulate several behaviour-related functions in the host. Faecalimonas sp. is
anaerobic bacteria affiliated with the family Lachnospiraceae, which represents a highly prevalent beneficial bacteria in the human gut and have potential to be used as next generation probiotic.
Methods: Faecalimonas sp. NGB245 was isolated from human fecal material by pre-inoculation in
BACTEC media followed by serial dilutions spreading on Columbia Blood Agar supplemented with cysteine and sodium thioglycolate in Whitley Anaerobic Workstation. Production of short chain fatty acid
(SCFA) was detected after bacterial growth in Columbia broth supplemented with cellobiose by HPLC.
Host response was followed on Caenorhabditis elegans model by evaluated expression of the genes involved in neurosignaling by qPCR.
Results: We showed that Faecalimonassp. NGB245 exhibits high capacity of production of SCFA including acetate (12,17 mM), propionate (3,02 mM) and butyrate (10,33 mM). Moreover, C. elegansfed with Faecalimonas sp. NGB245 showed higher expression of the genes involved in neurotransmitter synthesis
(tph-1, cat-2), neurotransmitter release (unc-64, snb-1, snt-1), neurotransmitter receptor (npr-1) and different classes of neuropeptides(flp-18, flp-21, nlp-28, nlp-29) in comparison to wormsfed with Escherichia
coli OP50, as a standard laboratory food.
Conclusion: The obtained results imply that Faecalimonas sp. NGB245 isolate could be considered as
next generation probiotic to be used in prevention and treatment of neurodegenerative and psychiatric
diseases.

AB  - Yogurt represent one of the oldest fermented foods containing viable lactic acid bacteria and many bioactive compounds that could exhibit beneficial effects on human health and train our immune system to better respond to invading pathogens. Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus are commonly used for yogurt preparation under controlled temperature and environmental conditions. In this study, we investigated probiotic features of S. thermophilus BGKMJ1-36 and L. bulgaricus BGVLJ1-21 strains isolated from artisanal sour milk and yogurt by using Caenorhabditis elegans as an in vivo model system. Further, we evaluated content of total fat, saturated fatty acids, proteins, and lactose, as well as vitamins and AA of yogurt prepared from above-mentioned starter cultures during 21 d of storage at 4°C to get insights of final product stability. We showed that S. thermophilus BGKMJ1-36 and L. bulgaricus BGVLJ1-21 strains applied in combination upregulated the expression of autophagy-related genes in C. elegans. Beside autophagy, we observed activation of TIR-1-dependent transcription of lysozyme-like antimicrobial genes involved in the immune defense of C. elegans. Upregulation of these genes strongly correlates with an increase in the longevity of the worms fed with yogurt culture bacteria. Further, we showed that yogurt prepared with S. thermophilus BGKMJ1-36 and L. bulgaricus BGVLJ1-21, as a final product, is rich with vitamin B2 and dominant AA known by their prolongevity properties. Taken together, our study pointed to the beneficial features of the tested starter cultures and yogurt and highlighted their potential to be used as a fermented food with added-value properties.

AB  - This study aimed to evaluate different commercial diets (Otohime C1, Aller Futura (AF), Biomar Inicio Plus (BIP)) and one experimental feed (EF) in terms of their effectiveness as post-larval diets for indoor weaned largemouth bass, LMB (Micropterus salmoides). Key variations in the content of nutritive values were monounsaturated fatty acid (MUFA) and highly unsaturated FA (HUFA) ω3. Fish were fed with one of four tested diets from the 33rd to the 40th day post-hatch (DPH). Biometric indices, digestive enzyme-specific activities, thyroid hormone status, and mRNA expression of genes coding for skeleton, neuron, and muscle growth were analyzed. The lowest skeletal deformity rate and highest survival among the treatments were seen in BIP-fed fish. Dietary lipids, with an appropriate balance between MUFA and polyunsaturated FA (PUFA), alongside amino acid balance, were shown to be the main contributors to the growth of the skeleton and/or fish survival. On the other hand, fish growth is correlated with fish digestive capacity and feed moisture percent rather than feed quality. Unexpectedly, BIP-fed fish were attributed with the lowest expression of skeleton differentiation markers, which may reflect the sacrifice of scale and/or cranium growth at the expense of somatic growth. This study highlights the role of non-marine ingredients in the nutrition of post-larval LMB.

AB  - This research aimed to test whether coating with Lactobacillus paracasei subsp. paracasei BGHN14 homogenate may increase soluble protein and amino acid amount on larval fish feed surface. Total amino acid and protein, as well as taste stimulating and growth promoting amino acid amounts were analyzed in coated feed samples. Results indicated that coating with BGHN14 homogenate increased the amount of soluble proteins and free Glycine on feed surface, as well as the availability of protein-bound (hydroxy-)Proline. This lab-scale research provides the basis for use of lactobacilli as resource efficient source of soluble nutrients for animal feedstuffs.

Total amino acid and protein, as well as taste stimulating and growth promoting amino acid amounts were analyzed in coated feed samples. Results indicated that coating with BGHN14 homogenate increased the amount of soluble proteins and free Glycine on feed surface, as well as the availability of protein-bound (hydroxy-)Proline. This lab-scale research provides the basis for use of lactobacilli as resource efficient source of soluble nutrients for animal feedstuffs.",

AB  - The present study is focused on the safety, technological characteristics, and probiotic evaluation of Enterococcus species from different artisanal raw milk dairy products, mainly cheeses with ripening. Apart from proteolytic and lipolytic activities, most enterococci show the ability to metabolize citrate and convert it to various aromatic compounds. Long-ripened cheeses therefore have a specific flavor that makes them different from cheeses produced from thermally treated milk with commercial starter cultures. In addition, enterococci are producers of bacteriocins effective against spoilage and pathogenic bacteria, so they can be used as food preservatives. However, the use of enterococci in the dairy industry should be approached with caution. Although originating from food, enterococci strains may carry various virulence factors and antibiotic-resistance genes and can have many adverse effects on human health. Still, despite their controversial status, the use of enterococci in the food industry is not strictly regulated since the existence of these so-called desirable and undesirable traits in enterococci is a strain-dependent characteristic. To be specific, the results of many studies showed that there are some enterococci strains that are safe for use as starter cultures or as probiotics since they do not carry virulence factors and antibiotic-resistance genes. These strains even exhibit strong health-promoting effects such as stimulation of the immune response, anti-inflammatory activity, hypocholesterolemic action, and usefulness in prevention/treatment of some diseases.

AB  - In this study, for the first time, the comprehensive analysis of antiproliferative and antioxidant activities of ramson, followed by the analysis of its associated microbiota and health-promoting effects of lactic acid bacteria (LAB), was performed. Ramson (Allium ursinum) is recognized as a medicinal plant with a long history of use in traditional medicine due to its antimicrobial and antioxidant activity. In this study the influence of in vitro gastrointestinal digestion on the cytotoxic activity of A. ursinum extracts against human malignant cell lines was demonstrated. Seven sulfur compounds, the degradation products of thiosulfinates, including diallyl disulfide were shown to inhibit proliferation of malignant cells by inducing accumulation within G2/M phase as well as to induce apoptosis through activation of caspase-3 and mitochondrial signaling pathway. Further, the A. ursinum microbiota, particularly LAB with potential probiotic effects, was analyzed by culture-dependent method and culture-independent method [denaturing gradient gel electrophoresis (DGGE)]. The obtained results revealed that the most abundant genera were Streptococcus, Lactobacillus, and Bacillus. The Lactobacillus genus was mainly represented by L. fermentum. The pulsed-field gel electrophoresis (PFGE) analysis revealed the presence of two PFGE pulsotypes. The probiotic potential of the strain L. fermentum BGSR163 belonging to PFGE pulsotype 1 and the strain L. fermentum BGSR227 belonging to the PFGE pulsotype 2 was characterized. The results revealed that both strains are safe for human use, successfully survive the simulated gastrointestinal conditions, have potential to transiently colonize the gastrointestinal tract (GIT) and have a protective immunomodulatory effect, inducing the production of proinflammatory cytokine IL17 and regulatory cytokine IL10, while decreasing the production of proinflammatory cytokine IFN-gamma. In conclusion, the results of this study suggest that consumption of A. ursinum might have health-promoting properties, including anticancer effects, while L. fermentum strains isolated from A. ursinum leaves could be used as probiotics for human consumption.

AB  - Yogurt is a traditional fermented dairy product, prepared with starter cultures containing Streptococcus thermophilus and Lactobacillus bulgaricus that has gained widespread consumer acceptance as a healthy food. It is widely accepted that yogurt cultures have been recognized as probiotics, due to their beneficial effects on human health. In this study, we have characterized technological and health-promoting properties of autochthonous strains S. thermophilus BGKMJ1-36 and L. bulgaricus BGVLJ1-21 isolated from artisanal sour milk and yogurt, respectively, in order to be used as functional yogurt starter cultures. Both BGKMJ1-36 and BGVLJ1-21 strains have the ability to form curd after five hours at 42 degrees C, hydrolyze alpha(s1)-, beta-, and kappa- casein, and to show antimicrobial activity toward Listeria monocytogenes. The strain BGKMJ1-36 produces exopolysaccharides important for rheological properties of the yogurt. The colonies of BGKMJ1-36 and BGVLJ1-21 strains that successfully survived transit of the yogurt through simulated gastrointestinal tract conditions have been tested for adhesion to intestinal epithelial Caco-2 cells. The results reveal that both strains adhere to Caco-2 cells and significantly upregulate the expression of autophagy-, tight junction proteins-, and anti-microbial peptides-related genes. Hence, both strains may be interesting for use as a novel functional starter culture for production of added-value yogurt with health-promoting properties.

AB  - This study aimed to analyze an impact of Lactobacillus salivarius BGHO1 and Lactobacillus reuteri BGGO6-55 supplemented to Anemia franciscana cultivation medium on biochemical profile of hatched nauplii. Impacts of different BGHO1:BGGO6-55 ratios (75:25, 50:50 and 25:75) and their total concentrations (250 and 500 g/kg of Anemia cysts) at different timings of bacteria application (pre- and post-hatching) were examined. The effects were evaluated by quantification of naupliar peptide, soluble protein, phospho-, neutral and unsaturated lipid content. Uni and multifactorial analysis of variance (ANOVA) were used to estimate the effects of treatments relative to control and to model factor interactions, respectively Statistical analysis indicated that posthatching application of 75:25 strain ratio at high dose was associated with an increase of neutral lipid amount. Furthermore, factor interaction profiling identified positive correlation of lacto-bacilli concentration with the level of free amino acids/short peptides, phospho-, neutral and unsaturated lipids, but only at 50:50 strain ratio combination. Application of lower lactobacilli dose at 75:25 strain ratio caused an increase of soluble protein and phospholipid amount. Hypothetically, graded response of Artemia nauplii to lactobacilli supplementation was induced with different BGHO1 doses. It assumedly ranged from stress-response protein synthesis at lower doses to membrane permeability alterations and triglyceride-mediated defense mechanism activation at higher BGHO1 doses. In contrast to lactobacilli supplementation after Anemia hatching, pre-hatching application of lactobacilli was not associated with an increase of Anemia nutritive profile, though again there was a positive association of lactobacilli concentration with nutrient amount. This implicates interference of lactobacilli with the hatching process. Results presented here facilitate the design of future studies aiming to modify Artemia nutritive profile in accordance with nutritional demands of cultivated fish species.

AB  - The aim of this review was to summarize the data regarding diversity of non-starter lactic acid bacteria (NSLAB) isolated from various artisanal dairy products manufactured in Western Balkan Countries. The dairy products examined were manufactured from raw cow's, sheep's or goat's milk or mixed milk, in the traditional way without the addition of commercial starter cultures. Dairy products such as white brined cheese, fresh cheese, hard cheese, yogurt, sour cream and kajmak were sampled in the households of Serbia, Croatia, Slovenia, Bosnia and Herzegovina, Montenegro, and North Macedonia. It has been established that the diversity of lactic acid bacteria (LAB) from raw milk artisanal dairy products is extensive. In the reviewed literature, 28 LAB species and a large number of strains belonging to the Lactobacillus, Lactococcus, Enterococcus, Streptococcus, Pediococcus, Leuconostoc and Weissella genera were isolated from various dairy products. Over 3000 LAB strains were obtained and characterized for their technological and probiotic properties including: acidification and coagulation of milk, production of aromatic compounds, proteolytic activity, bacteriocins production and competitive exclusion of pathogens, production of exopolysaccharides, aggregation ability and immunomodulatory effect. Results show that many of the isolated NSLAB strains had one, two or more of the properties mentioned. The data presented emphasize the importance of artisanal products as a valuable source of NSLAB with unique technological and probiotic features important both as a base for scientific research as well as for designing novel starter cultures for functional dairy food.

AB  - Listeria monocytogenes, the common foodborne pathogenic bacteria species, compromises the intestinal epithelial barrier, leading to development of the listeriosis, a severe disease especially among immunocompromised individuals. L. monocytogenes infection usually requires antibiotic treatment, however, excessive use of antibiotics promotes emergence of antibiotic resistance and the destruction of gut microbiota. Probiotics, including lactic acid bacteria (LAB), have been repeatedly proven as an alternative approach for the treatment of various infections. We have analyzed the potential of Enterococcus faecium BGPAS1-3, a dairy isolate exhibiting strong direct antilisterial effect, to modulate the response of differentiated Caco-2 intestinal epithelial cells to L. monocytogenes ATCC 19111 infection. We showed that the molecule with antilisterial effect is a bacterial cell-wall protein that is highly resistant to the high-temperature treatment. When we tested the antilisterial potential of heat-killed BGPAS1-3, we found that it could prevent tight junction disruption in differentiated Caco-2 monolayer infected with L. monocytogenes ATCC 19111, induce antilisterial host response mechanisms, and stimulate the production of protective TGF-beta in intestinal epithelial cells. We also showed that the modulation of MyD88 dependent TLR2 and TLR4 pathways by BGPAS1-3 are involved in host response against L. monocytogenes ATCC 19111. Since heat-killed BGPAS1-3 possess strong antilisterial effects, such postbiotic could be used as a controllable and safe therapeutic.

AB  - The aim of this research was to improve nutritive value of fishmeal-based feed by lactobacilli in order to achieve satisfactory nutrient availability needed to support fish development. Feed was solid-state treated at a laboratory scale with the combination of Lactobacillus paracaseisubsp. paracasei BGHN14 and Lactobacillus rhamnosus BGT10 in different experimental settings, which included the variation of strain ratio, total lactobacilli concentration, percentage of moisture and duration of incubation. Short peptides, soluble proteins, phospho-, neutral and unsaturated lipids were quantified. Differences among treated and control feeds were evaluated by Student t-test, while Gaussian process regression (GPR) modeling was employed to simulate the incubation process and define the optimal treatment combination in the context of overall feed nutritional profile. Treatment duration was shown to be the critical determinant of final outcome, either as single factor or via interaction with strain ratio. Optimal nutrient balance was achieved with 12 h incubation period, 260% moisture, 75:25 and 50:50 BGHN14:BGT10 ratios and 200 mg of lactobacilli per g of dry feed. This study should serve as the basis for large-scale tests which would simulate on-farm production of both fishmeal-based and unconventional, lower cost aquafeed with added value.

AB  - The ability of lactic acid bacteria to form multi-cellular aggregates via self-aggregation is regarded as an important mechanism for stress tolerance, adhesion, colonization and genetic material exchange. The novel aggLr gene encoding for the auto-aggregation promoting protein (AggLr) of Lactococcus raffinolactis BGTRK10-1 was cloned. Heterologous expression of AggLr enabled auto-aggregation, higher hydrophobicity and collagen and fibronectin binding of the carrier strains. Domain analysis and the type of aggregates formed by cells expressing AggLr confirmed that this aggregation factor belongs to the family of high molecular weight proteins that the authors propose to be called Snow-flake Forming Collagen Binding Aggregation Factors (SFCBAF). An additional feature of SFCBAF is that they are rich in threonine and lysine and are free of cysteine in all of the aggregation factors described so far. In contrast to previously discovered SFCBAF, the gene encoding for AggLr is located on the chromosome in the strain BGTRK10-1.

AB  - Enterococci have controversial status due to their emerging role in nosocomial infections and transmission of antibiotic resistance genes, while some enterococci strains are used as probiotics for humans and animals and starter cultures in dairy industry. In order to improve our understanding of factors involved in the safe use of enterococci as potential probiotics, the antibiotic susceptibility, virulence and probiotic traits of 75 dairy enterococci isolates belonging to Enterococcus durans (50), En. faeciurn (15), En. faecalis (6), En. italious (3), and En, hirae (1) were evaluated. The results revealed that ciprofloxacin resistance and biofilm formation are correlated with isolates originated from Golija mountain (Serbia), while gelatinase activity was more common in isolates from Prigorje region (Croatia), pointing to uncontrolled use of antibiotics and anthropogenic impact on dairy products" microbiota in these regions. The virulence genes were sporadically present in 13 selected dairy enterococci isolates. Interestingly, biofilm formation was correlated with higher ability of strains to reduce the adhesion of E. coil and Salmonella Enteritidis to HT29-MTX cells. To our knowledge this is the first study reporting the presence of the esp gene (previously correlated with pathogenesis) in dairy enterococci isolates, mostly associated with the genes involved in adhesion property. Hence, the results of this study revealed that the virulence genes are sporadically present in dairy isolates and more correlated to adhesion properties and biofilm formation, implicating their role in gut colonization rather than to the virulence traits.

AB  - The aim of this work was to design a novel mixed probiotic culture for piglets and to evaluate its beneficial effect on the piglets' gut health. The possible mechanisms of probiotic activity, such as adhesion, competitive pathogen exclusion and influence on gut microbiota diversity were determined. Mixed probiotic starter culture is composed of three thermophilic lactic acid bacteria (LAB) strains: Lactobacillus helveticus BGRA43, Lactobacillus fermentum BGHI14 and Streptococcus thermophilus BGVLJ1-44. The strains BGVLJ1-44 and BGRA43 showed good technological properties (fast milk curdling, strong proteolytic activity). In addition, the strain BGVLJ1-44 produces exopolysaccharide (EPS), BGHI14 is heterofermentative LAB strain with significant immunomodulatory effect, while the strain BGRA43 showed strong antimicrobial activity against different pathogens and exhibited significantly higher level of adhesion to Caco-2 cells comparing to other two strains. Both lactobacilli strains BGRA43 and BGHI14 (p  lt  0.05), as well as probiotic combination (p  lt  0.01) significantly reduced the adhesion of Escherichia coli ATCC25922 to Caco-2 cells, while the strains BGVLJ1-44 (p  lt  0.01) and BGRA43 (p  lt  0.05) significantly reduced adhesion of Salmonella 654/7E (veterinary isolate). The results of farm trial revealed that treatment of sows with new fermented dairy probiotic influenced the piglets' gut colonization with beneficial bacteria and reduced the number of enterobacteriaceae in litters from some treated sows (no significant due to high variability among animals). Finally, this is the first study reporting that the treatment of sows with probiotic combination resulted in the improved microbiota diversity in neonatal piglets.

The strains BGVLJ1-44 and BGRA43 showed good technological properties (fast milk curdling, strong proteolytic activity). In addition, the strain BGVLJ1-44 produces exopolysaccharide (EPS), BGHI14 is heterofermentative LAB strain with significant immunomodulatory effect, while the strain BGRA43 showed strong antimicrobial activity against different pathogens and exhibited significantly higher level of adhesion to Caco-2 cells comparing to other two strains. Both lactobacilli strains BGRA43 and BGHI14 (p  lt  0.05), as well as probiotic combination (p  lt  0.01) significantly reduced the adhesion of Escherichia coli ATCC25922 to Caco-2 cells, while the strains BGVLJ1-44 (p  lt  0.01) and BGRA43 (p  lt  0.05) significantly reduced adhesion of Salmonella 654/7E (veterinary isolate). The results of farm trial revealed that treatment of sows with new fermented dairy probiotic influenced the piglets' gut colonization with beneficial bacteria and reduced the number of enterobacteriaceae in litters from some treated sows (no significant due to high variability among animals). Finally, this is the first study reporting that the treatment of sows with probiotic combination resulted in the improved microbiota diversity in neonatal piglets.",

AB  - The understanding of mechanisms of interactions between various bacterial cell surface proteins and host receptors has become imperative for the study of the health promoting features of probiotic enterococci. This study, for the first time, describes a novel enterococcal aggregation protein, AggE, from Enterococcus faeciurn BGGO9-28, selected from a laboratory collection of enterococcal isolates with auto aggregation phenotypes. Among them, En. faecium BGG09-28 showed the strongest auto -aggregation, adhesion to components of ECM and biofilm formation. Novel aggregation promoting factor AggE, a protein of 178.1 kDa, belongs to the collagen -binding superfamily of proteins and shares similar architecture with previously discovered aggregation factors from lactic acid bacteria (LAB). Its expression in heterologous enterococcal and lactococcal hosts demonstrates that the aggE gene is sufficient for cell aggregation. The derivatives carrying aggE exhibited the ten times higher adhesion ability to collagen and fibronectin, possess about two times higher adhesion to mucin and contribute to the increase of biofilm formation, comparing to the control strains. Analysis for the presence of virulence factors (cytolysin and gelatinase production), antibiotic resistance (antibiotic susceptibility) and genes (cylA, egg, gelE, esp, hyiN, ace, efaks, and efagn) showed that BGG09-28 was sensitive to all tested antibiotics, without hemolytic or gelatinase activity. This strain does not carry any of the tested genes encoding for known virulence factors. Results showed that BGGO9-28 was resistant to low pH and high concentrations of bile salts. Also, it adhered strongly to the Caco-2 human epithelial cell line. In conclusion, the results of this study indicate that the presence of AggE protein on the cell surface in enterococci is a desirable probiotic feature.

AB  - Background: Genus Clostridium accompanies more than 200 known species and at least 30 among them are associated with human and animal diseases. At the moment, the treatment of clostridial infections is based on use of antibiotics. However, due to the European ban on the use of antibiotics in livestock production, novel therapeutic strategies for treatment of these hardly curable infections have been evaluated. Hence, in this study the antimicrobial effect of newly designed probiotic culture consisted of natural isolates Lactobacillus helveticus BGRA43, Lactobacillus fermentum BGHI14 and Streptococcus thermophilus BGVLJ1-44 against Clostridium difficile and Clostridium perfringens was analyzed. Results: The probiotic culture showed strong in vitro antimicrobial effect on C. difficile (human clinical isolate). In addition, individual strains and the probiotic combination exhibited immunomodulatory activity. The probiotic combination significantly increased the proliferation of GALT lymphocytes. At the other hand, none of the bacterial treatments (individual strains and the combination) induced the production of proinflammatory cytokines IL-6 and IL-1 beta by intestinal epithelial cells, Caco-2. Interestingly, Caco-2 cells exposed to the probiotic combination produced significantly elevated amount of TGF beta pointing to potential protecting effect of the probiotic. In addition, the results of field trial on spontaneously infected goats revealed reduction of C. perfringens in goats (below the detection threshold) after the probiotic treatment. Conclusions: The results of this study indicated that the novel probiotic deserves to be further investigated as a promising antimicrobial agent against C. difficile and C. perfringens.

AB  - Bosnian sudzuk is a dry fermented sausage produced in a rural household near the town of Visoko in central Bosnia and Herzegovina. This kind of sausage was manufactured only from beef and spices in a traditional way without the addition of a starter cultures. To identify lactic acid bacteria (LAB), a total number of 160 LAB strains were isolated from five samples of Bosnian sudzuk collected over 28 days of fermentation. Preliminary identification by phenotypic tests and 16S rDNA sequencing were performed for all 160 of the LAB isolates. Identification of LAB strains from traditionally produced Bosnian sausage at the species level revealed the presence of six genera: Lactococcus sp., Enterococcus sp., Leuconostoc sp., Lactobacillus sp., Pediococcus sp. and Weissella sp.. Among the 15 distinct species identified, the species Lactobacillus plantarum, Leuconostoc mesenteroides, Lactococcus lactis, Enterococcus faecalis and Enterococcus durans were present throughout the entire process of fermentation. Leuconostoc mesenteroides, Lactobacillus plantarum and Lactococcus lactis prevailed, with 21.8%, 19.3% and 13.1%, respectively, of total LAB strains during the entire fermentation process. Significant negative correlations (r = 0.892 and r = 0.829, respectively) between the presence of Weissella sp. and Lactobacillus sp., and between the presence of Weissella sp. and Lactococcus sp. were recorded. Lactobacillus plantarum, Enterococcus durans and Leuconostoc mesenteroides were the best producers of aromogenic compounds while 32.3% of Lactobacillus plantarum and 28.6% of Leuconostoc mesenteroides were produced exopolysaccharides.

AB  - Enterococci represent the most controversial group of dairy bacteria. They are found to be the main constituent of many traditional Mediterranean dairy products and contribute to their characteristic taste and flavor. On the other hand, during the last 50 years antibiotic resistant enterococci have emerged as leading causes of nosocomial infections worldwide. The aim of this study was to determine the diversity, technological properties, antibiotic susceptibility and virulence traits of 636 enterococci previously isolated from 55 artisan dairy products from 12 locations in the Western Balkan countries (WBC) of Serbia, Croatia and Bosnia and Herzegovina. All strains were identified both by microbiological and molecular methods. The predominant species was Enterococcus durans, followed by Enterococcus faecalis and Enterococcus faecium. Over 44% of the isolates were resistant to ciprofloxacin and erythromycin, while 26.2% of the isolates were multi resistant to three or more antibiotics belonging to different families. 185 isolates (29.1%) were susceptible to all 13 of the antibiotics tested. The antibiotic-susceptible isolates were further tested for possible virulence genes and the production of biogenic amines. Finally, five enterococci isolates were found to be antibiotic susceptible with good technological characteristics and without virulence traits or the ability to produce biogenic amines, making them possible candidates for biotechnological application as starter cultures in the dairy industry.
