AB  - The aim of the study was to test the potential of immunostimulating Limosilactobacillus fermentum BGHI14 strain to reduce the damage of colon tissue in rats with 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis. Wistar rats were treated with L. fermentum BGHI14 in the regime of preventive, therapeutic and continuous treatment 22 days prior to and/or 7 days after the administration of TNBS. After sacrifice, the colon tissue samples were taken for RNA isolation, gene expression analysis, histopathological analysis, and malondialdehyde measurement. Judging from the body weights, histopathological scores, malondialdehyde levels and transcription of IL-1β and Tight junction protein 1 (Tjp-1) coding genes, preventive and therapeutic treatment proved to be the most protective in the applied conditions. On the other hand, continuous treatment did not affect the intensity of tissue damage. Considering these results, we discussed the possible mechanisms which might stand behind the protective action of immunostimulating probiotic bacteria in the case of mucosal barrier damage.

AB  - Biofilm production facilitates microbial colonization of wounds and catheters. Acinetobacter baumannii produces high levels of biofilm and causes difficult-to-treat nosocomial infections. Candida albicans is another strong biofilm producer which may facilitate A. baumannii adhesion by providing hyphae-mediated OmpA-binding sites. Here we tested the potential of 2′-hydroxychalcones to inhibit dual-species biofilm production of A. baumannii and Candida spp., and further predicted the mechanism of structure-related difference in activity. The results suggest that 2′-hydroxychalcones exhibit potent activity against Candida spp./A. baumannii dual-species biofilm production. Particularly active was trifluoromethyl-substituted derivative (p-CF3), which decreased C. albicans/A. baumannii biomass produced on vein-indwelling parts of the central venous catheterization set by up to 99%. Further, higher OmpA-binding affinity was also calculated for p-CF3, which together with demonstrated significant ompA-downregulating activity, suggests that superior antibiofilm activity of this chalcone against the tested dual-species community of A. baumannii is mediated through the OmpA.

AB  - Multidrug-resistant bacterial strains represent an emerging global health threat and a great obstacle for bone tissue
engineering. One of the major components of the extracellular matrix of the bone is a collagen protein, while selenium is an
element that has antimicrobial potential, and is also important for bone metabolism and bone health. Here we represent the
incorporation of selenium nanoparticles (SeNPs) synthesized by the green chemical reduction method into collagen gels to
produce a composite material, collagen/SeNPs, with antimicrobial properties. The samples were comprehensively
characterized by zeta potential measurements, dynamic light scattering inductively coupled plasma-mass spectrometry
(ICP-MS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), optical microscopy, field-emission
scanning electron microscopy (FE-SEM), and differential scanning calorimetry The cytotoxicity of the SeNPS, as well as
collagen/SeNPs, was tested on the MRC-5 cells. It was revealed that collagen/SeNPS expressed a lower cytotoxic effect.
Collagen/SeNPs showed significant antibacterial activity against all tested Gram-positive strains, the major causative agents
of orthopedic infections as well as Candida albicans. Furthermore, three-dimensional β-tricalcium phosphate (3D-TCP)
scaffolds were fabricated by a well-established 3D printing (lithography) method, and afterward preliminary coated by
newly-synthesized SeNPs or collagen/SeNPs. In addition, uncoated 3D-TCP scaffolds as well as coated by collagen/SeNPs
were subjected to biofilm formation. The production of Staphylococcus aureus biofilm on coated scaffolds by collagen/SeNPs
was significantly reduced compared to the uncoated ones.

AB  - Aims To investigate the synergistic activity of colistin and selenium nanoparticles (SeNPs) against pandrug-resistant (PDR) Ac. baumannii. Methods and Results Chequerboard and time-kill assays were employed to explore the potential synergistic interactions between colistin and SeNPs against Ac. baumannii isolates (8), previously determined as colistin-resistant (MIC range 16-256 mu g ml(-1)). Also, whole-genome sequencing (WGS) and gene expression analyses were used to elucidate the mechanisms of colistin resistance. Exceptionally strong synergistic activity (FICI range 0.004-0.035) of colistin and SeNPs against colistin-resistant isolates was revealed. Colistin (0.5 or 1 mu g ml(-1)) used in combination with SeNPs (0.5 mu g ml(-1)) was able to reduce initial inoculum during the first 4 h of incubation, in contrast to colistin (0.5, 1 or 2 mu g ml(-1)) alone. Conclusions These findings propose colistin/SeNPs combination as a new option to fight PDR Ac. baumannii, the therapeutic possibilities of which should be proved in future in vivo studies. Significance and Impact of Study Here we present the first evidence of synergy between colistin and selenium compounds against bacteria in general. Also, WGS and gene expression analyses provide some new insights into Ac. baumannii colistin resistance mechanisms.

AB  - An increasing lack of available therapeutic options against Acinetobacter baumannii urged researchers to seek alternative ways to fight this extremely resistant nosocomial pathogen. Targeting its virulence appears to be a promising strategy, as it offers considerably reduced selection of resistant mutants. In this study, we tested antibiofilm potential of four synthetic chalcone derivatives against A. baumannii. Compound that showed the greatest activity was selected for further evaluation of its antivirulence properties. Real-time PCR was used to evaluate mRNA expression of biofilm-associated virulence factor genes (ompA, bap, abaI) in treated A. baumannii strains. Also, we examined virulence properties related to the expression of these genes, such as fibronectin- and collagen-mediated adhesion, surface motility, and quorum-sensing activity. The results revealed that the expression of all tested genes is downregulated together with the reduction of adhesion and motility. The conclusion is that 2 '-hydroxy-2-methoxychalcone exhibits antivirulence activity against A. baumannii by inhibiting the expression of ompA and bap genes, which is reflected in reduced biofilm formation, adhesion, and surface motility.

abstract = "An increasing lack of available therapeutic options against Acinetobacter baumannii urged researchers to seek alternative ways to fight this extremely resistant nosocomial pathogen. Targeting its virulence appears to be a promising strategy, as it offers considerably reduced selection of resistant mutants. In this study, we tested antibiofilm potential of four synthetic chalcone derivatives against A. baumannii. Compound that showed the greatest activity was selected for further evaluation of its antivirulence properties. Real-time PCR was used to evaluate mRNA expression of biofilm-associated virulence factor genes (ompA, bap, abaI) in treated A. baumannii strains. Also, we examined virulence properties related to the expression of these genes, such as fibronectin- and collagen-mediated adhesion, surface motility, and quorum-sensing activity. The results revealed that the expression of all tested genes is downregulated together with the reduction of adhesion and motility.

AB  - Acinetobacter baumannii and Pseudomonas aeruginosa are frequent multiresistant nosocomial pathogens that cause wound and pulmonary infections in hospitalized patients. As being increasingly resistant to most clinically available antibiotics, there is a constant need for exploration of new substances that could kill them or inhibit their growth, or alternatively inhibit some of their essential virulence factors. Chalcones are chemical compounds with well-documented antimicrobial potential. The aim of this study was to examine effectiveness of four newly-synthesized chalcones against the multiresistant clinical strains of A. baumannii and P. aeruginosa. Antibacterial activity of chalcones was investigated with broth-microdilution test and time-dependent killing assay. Synergistic effects of tested compounds with antibiotics (meropenem, amikacin and ciprofloxacin) were determined by checkerboard assay. The effects of chalcones on expression of virulence factors in P. aeruginosa (pyocyanin production, swimming and swarming motility) and A. baumannii (twitching and surface-associated motility), along with their biofilm production, were also examined. The obtained results indicate substantial antimicrobial activity of the tested chalcones (MICs = 100–175 μg/mL) and several synergistic interactions with antibiotics, as well as notable reduction in expression of all investigated virulence factors. These promising results may constitute a good basis for further research.

AB  - The aim of this study was to test the potential of high molecular weight exopolysaccharide (EPS) produced by the putative probiotic strain Lactobacillus paraplantarum BGCG11 (EPS CG11) to alleviate inflammatory pain in Wistar rats. The EPS CG11 was isolated from bacterial surface and was subjected to Fourier-transform infrared spectroscopy (FTIR) and thermal analysis. FTIR spectra confirmed the polysaccharide structure of isolated sample, while the thermal methods revealed good thermal properties of the polymer. The antihyperalgesic and antiedematous effects of the EPS CG11 were examined in the rat model of inflammation induced by carrageenan injection in hind paw. The results showed that the intraperitoneal administration of EPS CG11 produced a significant decrease in pain sensations (mechanical hyperalgesia) and a paw swelling in a dose-dependent manner as it was measured using Von Frey anesthesiometer and plethysmometer, respectively. These effects were followed by a decreased expression of IL-1 beta and iNOS mRNAs in rat's paw tissue suggesting that the antihyperalgesic and antiedematous effects of the EPS CG11 are related to the suppression of inflammatory response. Additionally, we demonstrated that EPS CG11 exhibits immunosuppressive properties in the peritonitis model induced by carrageenan. Expression levels of pro-inflammatory mediators IL-1 beta, TNF-alpha and iNOS were decreased, together with the enhanced secretion of anti-inflammatory IL-10 and IL-6 cytokines, while neutrophil infiltration was not changed. To the best of our knowledge, this is the first study which reports an antihyperalgesic effect as the novel property of bacterial EPSs. Given the high demands of pharmaceutical industry for the replacement of commonly used analgesics due to numerous side effects, this study describes a promising natural compound for the future pharmacological testing in the area.

AB  - The aim of this study was to investigate the potential of postbiotics originated from Lactobacillus fermentum BGHV110 strain (HV110) to counteract acetaminophen (APAP)-induced hepatotoxicity in HepG2 cells. This strain was selected according to its autophagy inducing potential, based on previous studies reporting protective role of autophagy in APAP caused cellular damage. Cell viability was assessed using MTT and LDH assays, while autophagy was monitored by qPCR analysis of BECN1, Atg5, p62/SQSTM1, and PINK1 mRNA expression and by Western blot analysis of p62/SQSTM1 and lipidated LC3 accumulation. Our results showed that detrimental effect of APAP on cell viability was suppressed in the presence of HV110 which was linked with increased conversion of LC3 protein and p62/SQSTM1 protein degradation. Additionally, higher p62/SQSTM1 and PINK1 mRNA transcription were noticed in cells co-treated with APAP/HV110, simultaneously. In conclusion, this study suggests that HV110 enhances activation of PINK1-dependent autophagy in HepG2 cells and its eventual co-supplementation with APAP could be potentially used for alleviation of hepatotoxic side effects caused by APAP overdose.

AB  - In the light of the increasing resistance of bacterial pathogens to antibiotics, one of the main global strategies in applied science is development of alternative treatments, which would be safe both for the host and from the environmental perspective. Accordingly, the aim of this study was to test whether two lactic acid bacteria (LAB) strains, Lactococcus lactis BGBU1-4 and Lactobacillus salivarius BGHO1, could be applied as safe supplements for Listeria infection. Two major research objectives were set: to compare the effects of BGBU1-4 and BGHO1 on early immune response in gut tissue of Wistar rats co-administered with Listeria monocytogenes ATCC19111 and next, to test how this applies to their usage as therapeutics in acute ATCC19111 infection. Intestinal villi (IV), Peyer's patches (PP) and mesenteric lymph nodes (MLN) were used for the analysis. The results showed that BGHO1 increased the mRNA expression of innate immune markers CD14, interleukin (IL)-1 beta and tumour necrosis factor (TNF)-alpha in PP and IV, and, in parallel, caused a decrease of listeriolysin O (LLO) mRNA expression in same tissues. In MLN of BGHO1 treated rats, LLO expression was increased, along with an increase of the expression of OX-62 mRNA and CD69, pointing to the activation of adaptive immunity. On the other hand, in BGBU1-4 treated rats, there was no reduction of LLO mRNA expression and no induction of innate immunity markers in intestinal tissue. Additionally, CD14 and IL-1 beta, as well as LLO, but not OX-62 mRNA and CD69 expression, were elevated in MLN of BGBU1-4 treated rats. However, when applied therapeutically, both, BGBU1-4 and BGHO1, lowered Listeria count in spleens of infected rats. Our results not only reveal the potential of LAB to ameliorate Listeria infections, but suggest different immunological effects of two different LAB strains, both of which could be effective in Listeria elimination.

AB  - Aim of this work was to assess the metabolic and physiological changes that occurred in the hind gut of rats after feeding with soybean carbohydrates alone and in combination with Lactobacillus helveticus BGRA43. Wistar rats were gavaged with soybean flour for 28 days. The parameters assessed included fecal volatile organic compounds, and L-lactate, reducing sugars, proteins, ammonia and water levels in the colonic lumen. The presence of lactic acid (LAB), sulfate reducing (SRB) and methanogenic bacteria was assessed by semi-quantitative PCR. Malondialdehyde levels as well as lymphoid tissue size in ileal and colonic mucosa were also evaluated. On the basics of the results obtained, correlation network was created, setting the parameters tested in research in two metabolic groups: saccharolytic and proteolytic fermentation group. The principal finding of the study is a negative correlation between oral administration of BGRA43 and increase of parameters related to carbohydrate fermentation in the gut, and a positive correlation to factors related to proteolytic fermentation. On the contrary, soybean carbohydrates were correlated with increased values of factors related to carbohydrate catabolism. Different effects of BGRA43 and soybean carbohydrates on metabolic processes in colonic lumen indicate the possibility of applying the BGRA43 in alleviating the gastrointestinal symptoms occurring after consuming hardly digestible carbohydrates.

AB  - Cyclohexane, dichloromethane, and methanol extracts of the medicinal mushroom Laetiporus sulphureus were tested for their antimicrobial, cytotoxic, and radical scavenging activities. Total polyphenol content was also determined. Regarding the amount of the phenolic compounds in the methanol extract, there were 14.1 +/- 0.6 mg gallic acid/g dry extract and a concentration of 0.66 +/- 0.15 mg/mL resulted in the removal of 50% of the DPPH radicals (half-maximal inhibitory concentration [IC50]) . The average minimum inhibitory concentrations (MICs) against a select panel of microorganisms were between 125 and 250 mu g/mL, and the methanolic extract significantly inhibited the growth of Staphylococcus aureus (MIC, 31.25 mu g/mL). Also, cyclohexane and dichloromethane extracts inhibited the growth of Helicobacter pylori (MIC, 62.5 mu g/mL). Cyclohexane and dichloromethane extracts showed higher antiproliferative action compared with the methanol extract. The lowest IC50 was induced on HeLa cells by dichloromethane extract (IC50,67.20 +/- 5.49 mu g/mL), followed by cyclohexane extract (IC50 75.91 +/- 1.57 mu g/mL). The tested cyclohexane and dichloromethane extracts possessed moderate antibacterial and significant cytotoxic activity against both malignant (HeLa and N87) and healthy (MRC5) cell lines. Methanol extracts exhibited promising anti-Helicobacter activity without cytotoxicity against N87 and MRC5 cell lines.

AB  - The present study evaluated the anti-Helicobacter pylori activity of Alchemilla glabra Neygenf. (A. sect. Alchemilla), A. monticola Opiz (A. sect. Plicatae S.E. Frohner), A. fissa Gunther & Schummel (A. sect. Calycinae (Buser) Buser) and A. viridiflora Rothm. (A. sect. Calycinae), and identified ellagic acid and quercetin-3-O-beta-D-glucoside. Anti-H. pylori activity was tested against ten clinical isolates and one reference strain (ATCC 43504). The methanol extracts were more active than the dichloromethane and cyclohexane extracts. The ranges of concentrations were between 4 mu g/mL for methanol extracts of A. viridiflora, A. glabra and A. monticola, and 256 mu g/mL for cyclohexane extracts of A. viridiflora, A. glabra and A. fissa. The best overall activity was obtained with A. monticola extracts. No significant difference was found in the ellagic acid contents of the methanol extracts of the tested Alchemilla species (0.2-0.3 mg/mL), and anti-H. pylori activity was similar (4-32 mu g/mL). Ellagic acid exhibited strong activity at very low concentrations (0.125-0.5 mu g/mL), while the second identified compound, quercetin-3-O-beta-D-glucoside, was also very active in concentration of 2-16 mu g/mL.

AB  - Modern research in the area of probiotics is largely devoted to discovering factors that promote the adherence of probiotic candidates to host mucosal surfaces. The aim of the present study was to test the role of aggregation factor (AggL) and mucin-binding protein (MbpL) from Lactococcus sp. in adhesion to gastrointestinal mucosa. In vitro, ex vivo, and in vivo experiments in rats were used to assess the adhesive potential of these two proteins expressed in heterologous host Lactobacillus salivarius BGHO1. Although there was no influence of MbpL protein expression on BGHO1 adhesion to gut mucosa, expression of AggL had a negative effect on BGHO1 binding to ileal and colonic rat mucosa, as well as to human HT29-MTX cells and porcine gastric mucin in vitro. Because AggL did not decrease the adhesion of bacteria to intestinal fragments in ex vivo tests, where peristaltic simulation conditions were missing, we propose that intestinal motility could be a crucial force for eliminating aggregation-factor-bearing bacteria. Bacterial strains expressing aggregation factor could facilitate the removal of pathogens through the coaggregation mechanism, thus balancing gut microbial ecosystems in people affected by intestinal bacteria overgrowth.

AB  - The present study was carried out to test the colonic mucosal response of rats to oral supplementation with Lactobacillus fermentum BGHI14 and to correlate the tissue reaction to trinitrobenzenesulfonate (TNBS)-induced colitis with mucosal barrier alterations caused by bacterial ingestion. An immune cell-mediated reaction of healthy colonic tissue was noticed after bacterial feeding. After prolonged bacterial treatment, the observed reaction had retreated to normality, but the mRNA levels of proinflammatory cytokines interleukin-1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF-alpha) remained elevated. These data point to the chronic low-grade inflammation that could be caused by long-term probiotic consumption. Although no detrimental effects of bacterial pretreatment were noticed in colitic rats, at least in the acute state of disease, the results obtained in our study point to the necessity of reassessment of existing data on the safety of probiotic preparations. Additionally, probiotic effects in experimental colitis models might depend on time coordination of disease induction with treatment duration.
