AB  - The formation of biofilms by foodborne pathogens
is a constant challenge in the food industry,
leading to an increased risk of contamination and
compromising food safety. Many of the chemicals
commonly used for sanitation in the food industry
are unable to remove biofilms, are harmful
to surfaces and can be toxic. The effectiveness
of disinfectants can be improved using enzymes
that specifically target biofilm components such
as exopolysaccharides, extracellular DNA, or proteins.
In this study we investigated the potential
of glycoside hydrolases originating from the
gill microbiota of freshwater fish to control biofilm
formation in the most common foodborne
pathogens. We demonstrated that β-glucosidase
from Microbacterium sp. BG28 (BglB-BG28) effectively
inhibits cellulose-rich biofilms formed by
Salmonella enteritidis, S. typhimurium, S. infantis,
and Escherichia coli. When these bacteria were cultivated overnight with 200 μL/mL enzyme, up
to 80% less biofilm was formed. By fluorescence
microscopy, we visualised the inhibition of biofilms
on plastic, glass and aluminium, materials
commonly used in the food industry. When used
as a pre-treatment, BglB-BG28 increased the
bactericidal efficacy of Oxicid®S, a commercially
available surface disinfectant. Its effectiveness at
temperatures up to 50 °C and in a pH range from
4 to 8 together with compatibility with non-ionic
detergents and high tolerance to sodium chloride
and glucose give BglB-BG28 advantages in
harsh and diverse industrial environments. Importantly,
no toxicity to Caenorhabditis elegans
was observed at enzyme concentrations of up
to 1 mg/ml. Overall, these results demonstrate
the suitability of the β-glucosidase BglB-BG28 for
the formulation of a novel enzyme-based disinfectant
to be used in food processing facilities.

AB  - Here, an artificial intelligence (AI)-based approach was employed to optimize the production of electrospun scaffolds for in vivo wound healing applications. By combining polycaprolactone (PCL) and poly(ethylene glycol) (PEG) in various concentration ratios, dissolved in chloroform (CHCl3) and dimethylformamide (DMF), 125 different polymer combinations were created. From these polymer combinations, electrospun nanofiber meshes were produced and characterized structurally and mechanically via microscopic techniques, including chemical composition and fiber diameter determination. Subsequently, these data were used to train a neural network, creating an AI model to predict the optimal scaffold production solution. Guided by the predictions and experimental outcomes of the AI model, the most promising scaffold for further in vitro analyses was identified. Moreover, we enriched this selected polymer combination by incorporating antibiotics, aiming to develop electrospun nanofiber scaffolds tailored for in vivo wound healing applications. Our study underscores three noteworthy conclusions: (i) the application of AI is pivotal in the fields of material and biomedical sciences, (ii) our methodology provides an effective blueprint for the initial screening of biomedical materials, and (iii) electrospun PCL/PEG antibiotic-bearing scaffolds exhibit outstanding results in promoting neoangiogenesis and facilitating in vivo wound treatment.

AB  - SalmonellaEnteritidis is the most commonly reported pathogen for foodborne illness outbreaks in both underdeveloped and developed regions. S. Enteritidis biofilms, which form on various food contact surfaces, are resistant to conventional physical and chemical cleaning and disinfection procedures routinely used in food processing. The aim of this study was to identify novel, industrially applicable enzymes that are active against S. Enteritidis biofilms. We describe the properties and anti-biofilm activity of heterologously expressed β-glucosidase B derived from the environmental strain Microbacterium sp. BG28 (BglB-BG28) collected from gills of bream fish. The enzyme inhibited adhesion and the early stages of biofilm formation in clinical isolates of S. Enteritidis. At a concentration of 200 μg/mL, BglB-BG28 effectively reduced biofilm formation, by decreasing biofilm biomass by 50% and metabolic activity within biofilms by 80%. The enzyme reduced the formation of air-liquid biofilms on various surfaces, including plastic, glass and metal, as observed by fluorescence microscopy. BglB-BG28 inhibited biofilm formation in Escherichia coli, another important food pathogen that also forms cellulose-rich biofilms. Using o-NPG as substrate, the enzyme showed activity at temperatures up to 50 °C and in a pH range between 4 and 8, high tolerance to sodium chloride and glucose, and compatibility with nonionic detergents. Importantly, no toxicity was observed in the model system Caenorhabditis elegans even at an enzyme concentration of 1 mg/mL. These results suggest that the β-glucosidase BglB-BG28 is a promising candidate for the development of a new enzyme-based disinfection protocol that can be used in food processing facilities.

AB  - The rapid emergence and spread of multidrug-
resistant pathogens present a global
healthcare challenge. One common cause of
resistance and/or tolerance to antibiotics is
biofilms, a complex communities of bacteria
embedded in a self-produced matrix. Biofilm
formation and maturation are regulated by
quorum sensing, a cell density-dependent communication
system that relies on the synthesis,
diffusion, and detection of small signaling molecules
- autoinducers (AIs). Quorum quenching
(QQ) enzymes that cut Ais emerged as a promising
strategy for persistent bacterial infections.
However, a significant drawback for the use of
QQ enzymes as therapeutics is their poor stability
and efficacy in vivo. Since one of the major
health issues linked to biofilm development is
persistent wound infections, our goal was to
improve enzyme properties by immobilizing it
on a natural biopolymer to make it suitable for
use as a wound dressing. The best candidate for immobilization was YtnP lactonase from Bacillus
paralicheniformis ZP1, as in concentrations
higher than 25 μg/mL it improved the survival of
Pseudomonas aeruginosa PAO1-infected zebrafish,
rescuing 80% of embryos. When combined
with tobramycin or gentamicin, the survival
rate of zebrafish embryos increased to 100%.
Purified YtnP lactonase at a concentration of 1
mg was immobilized on 10 mg of polymer disks
by crosslinking with glutaraldehyde. Specific
modifications of the polymer were also made to
eliminate the use of glutaraldehyde, which is a
skin irritant. In in vivo experiments on a murine
chronic wound model, immobilized enzyme
inhibited biofilm development, cleared already
formed biofilms, and overall improved wound
healing. These results provide a foundation for
the development of advanced wound dressings
that will prevent infection development in
wounds and enable proper therapy for infected
chronic wounds.

AB  - Biofilms are ubiquitous in nature, and the food industry is vulnerable to the risks posed by
biofilm formation. Not only do they interfere with the food production process, but they also
pose a public health threat. However, complete elimination of biofilms on food and food
contact surfaces cannot be achieved by conventional methods (cleaning and disinfection)
alone. New biofilm control strategies must be developed to prevent its formation and/or
persistence. Novel approaches may be based on enzymes that depolymerize components
of the biofilm matrix, making bacterial cells accessible to antimicrobial agents.
Environmental microorganisms are an inexhaustible source of new enzymes. In
Salmonella Enteritidis and Escherichia coli, known foodborne pathogens, cellulose is an
important component of the biofilm matrix, so our isolates from untapped environments
were tested for cellulolytic activity. Of the more than 70 isolates examined, isolate BG28
was selected as the most promising. Its genome was sequenced, annotated, and it was
identified as Gram-positive Microbacterium sp. Genome mining revealed the presence of
four complete genes for different β-glucosidases, one of three enzyme types of cellulase
complexes. To select the best candidate for heterologous expression DeepTMHMM,
ProtParam, and SoluProt were used to predict the presence/absence of signal peptide
and transmembrane domains, instability index, aliphatic index, hydrophilicity, and soluble
expression in E. coli. Based on the prediction results, the gene annotated as β-glucosidase
B was selected for recombinant expression. In addition, I-TASSER was used to model the
tertiary structure of the selected enzyme.
The β-glucosidase B was recombinantly expressed, purified, and tested for its anti-biofilm
activity. It was active and showed a 50% inhibitory effect on S. Enteritidis and E. coli biofilm
formation at a concentration of 100 μg/ml. To further evaluate this in silico approach in
the preselection of candidate enzymes for recombinant expression and purification, we
will use it to identify other enzymes of the cellulase complex.

abstract = "Biofilms are ubiquitous in nature, and the food industry is vulnerable to the risks posed by
biofilm formation. Not only do they interfere with the food production process, but they also
pose a public health threat. However, complete elimination of biofilms on food and food
contact surfaces cannot be achieved by conventional methods (cleaning and disinfection)
alone. New biofilm control strategies must be developed to prevent its formation and/or
persistence. Novel approaches may be based on enzymes that depolymerize components
of the biofilm matrix, making bacterial cells accessible to antimicrobial agents.
Environmental microorganisms are an inexhaustible source of new enzymes. In
Salmonella Enteritidis and Escherichia coli, known foodborne pathogens, cellulose is an
important component of the biofilm matrix, so our isolates from untapped environments
were tested for cellulolytic activity. Of the more than 70 isolates examined, isolate BG28
was selected as the most promising. Its genome was sequenced, annotated, and it was
identified as Gram-positive Microbacterium sp. Genome mining revealed the presence of
four complete genes for different β-glucosidases, one of three enzyme types of cellulase
complexes. To select the best candidate for heterologous expression DeepTMHMM,
ProtParam, and SoluProt were used to predict the presence/absence of signal peptide
and transmembrane domains, instability index, aliphatic index, hydrophilicity, and soluble
expression in E. coli. Based on the prediction results, the gene annotated as β-glucosidase
B was selected for recombinant expression. In addition, I-TASSER was used to model the
tertiary structure of the selected enzyme.
The β-glucosidase B was recombinantly expressed, purified, and tested for its anti-biofilm
activity. It was active and showed a 50% inhibitory effect on S. Enteritidis and E. coli biofilm
formation at a concentration of 100 μg/ml. To further evaluate this in silico approach in
the preselection of candidate enzymes for recombinant expression and purification, we
will use it to identify other enzymes of the cellulase complex.",

AB  - Pseudomonas aeruginosa is an opportunistic pathogen that can cause severe chronic
infections due to its exceptional ability to form a biofilm. Regulation of biofilm formation
is very sophisticated and involves multiple bacterial systems and regulatory pathways.
We found an enzyme MhqO dioxygenase from Bacillus paralicheniformis ZP1, which
was effective in the inhibition of biofilm formation and disruption of mature biofilm
of P. aeruginosa. Our results suggest that MhqO exerts its effect at the adhesion level,
preventing cells from attaching to the surface. We have also shown that the enzyme
stimulates the rhamnolipids synthesis.
To elucidate the mechanism of enzyme action, we analyzed the transcriptome of the P.
aeruginosa PAO1 strain treated with MhqO. Since cell adhesion occurs at the beginning
of the stationary phase growth, the PAO1 strain was treated with MhqO for four hours,
followed by total RNA isolation and cDNA synthesis. Transcriptome sequencing was
performed by Illumina NovaSeq 6000 and data were analyzed by Novogene Bioinformatics
Technology Co., Ltd. (Beijing, China).
Obtained data showed that 122 genes were up-regulated, 41 genes were down-regulated,
and the expression of 5947 genes was not changed. Five genes whose expression was
altered are directly related to biofilm formation. MhqO increased the expression of the
RsmA post-transcriptional regulator in P. aeruginosa. Transcriptome data revealed that pili
IV biosynthesis genes were up-regulated, which is in accordance with literature data that
RsmA positively regulates these genes. The inhibition of cells’ attachment to the surface
could be explained by these results. In addition, RsmA positively regulates rhamnolipid
production but negatively regulates biofilm matrix synthesis, which was supported by
expression levels in the sequenced transcriptome.
Data obtained from transcriptome analysis suggest that P. aeruginosa treated with MhqO
dioxygenase should be more sensitive to oxidative and osmotic stress, as well as to
beta-lactam antibiotics. Our further investigations should confirm these effects at the
phenotypic level as well.

AB  - Candidiasis caused by Candida albicans is one of the most common fungal infections in modern society. The limited arsenal of clinical drugs, their side effects and emerging resistance, largely contribute to the low efficacy of current antifungal therapies. The morphogenetic yeast-to-hyphae transition is the key virulence feature for the establishment of local and systemic C. albicans infections. We show that a delfinidin-rich fruit extract from Aristotelia chilensis ([Molina], Stuntz) (maqui berry) inhibits filamentation of C. albicans, in both laboratory and clinical strains. The extract acts synergistically with nystatin, with filament formation completely prevented by the combination of ¼×MIC of nystatin and 0.125 mg/ml of the extract. The combination treatment results in increased survival of C. albicans-infected zebrafish embryos compared to treatment with nystatin. Neither the extract nor its combination with nystatin was toxic at effective doses. These results warrant further investigation of maqui berry extract as adjuvant antifungal treatment.

AB  - About one in ten people contract a foodborne illness within a year. Children under the age of five are
the most affected, with 125,000 deaths each year. Many of the foodborne illness outbreaks can be
linked to the presence of biofilms in the food industry, and Salmonella enteritidis is an extremely
important foodborne pathogen that thrives in these conditions. It has been shown that biofilms can be
resistant to physical and chemical treatments used in cleaning and disinfection procedures in food
processing. The problem with using more aggressive disinfectants is that they often violate food safety
regulations. The use of enzymes which degrade biofilm matrix structural components should facilitate
current disinfection procedures and not compromise food safety. In this study, the anti-biofilm activity
of recombinantly expressed β-glucosidase B and its potential use as a protective agent to control
Salmonella biofilm formation is investigated. The putative target of this enzyme is cellulose, the
structural component of the Salmonella biofilm matrix. β-Glucosidase B deriving from the
environmental strain Microbacterium sp. BG28 was heterologously expressed in Escherichia coli and
successfully purified by affinity chromatography. The anti-biofilm activity of the enzyme was
evaluated in in vitro assays using various clinical isolates of S. enteritidis. The toxicity of the enzyme
was studied in Caenorhabditis elegans. β-glucosidase B effectively inhibited the formation of
Salmonella biofilms grown in a temperature range of 8°C to 37°C, achieving 50% inhibition at
concentrations of 100μg/ml. Biochemical characterization showed that the optimal pH activity of the
enzyme is between 6 and 7, with the highest activity observed at temperatures between 37°C and 47°C.
The absence of toxicity and other presented results indicate that beta-glucosidase B can be used in
biofilm control in the food industry.

AB  - Novel bacterial topoisomerase inhibitors (NBTIs) are new promising antimicrobials for the treatment of multidrug-resistant bacterial infections. In recent years, many new NBTIs have been discovered, however most of them struggle with the same issue - the balance between antibacterial activity and hERG-related toxicity. We started a new campaign by optimizing the previous series of NBTIs, followed by the design and synthesis of a new, amide-containing focused NBTI library to reduce hERG inhibition and maintain antibacterial activity against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). This optimization strategy yielded the lead compound 12 that exhibits potent antibacterial activity against Gram-positive bacteria, reduced hERG inhibition, no cardiotoxicity in zebrafish model, and a favorable in vivo efficacy in a neutropenic murine thigh infection model of MRSA infection.

AB  - Bacterial infections have become increasingly difficult to treat due to the occurrence of antibiotic-resistant strains. A promising strategy to increase the efficacy of therapy is to combine antibacterials with agents that decrease pathogen virulence via the modulation of the quorum sensing (QS). Lactonases inhibit acylated homoserine lactone (AHL)-mediated QS in Gram-negative bacteria, including the leading nosocomial pathogen Pseudomonas aeruginosa. Here we describe the characteristics of heterologously expressed YtnP lactonase from Bacillus paralicheniformis ZP1 (YtnP-ZP1) isolated from agricultural soil using the culture enrichment method. Purified YtnP-ZP1 hydrolyzed different AHLs with preference to substrates with long acyl residues as evaluated in assays with biosensors and HPLC. The enzyme showed good thermostability and activity in a wide temperature range. YtnP-ZP1 in 50 mu g mL(-1) concentration reduced the amount of P. aeruginosa-produced long-chain AHLs by 85%, while it hydrolyzed 50% of short-chain AHLs. Incubation of P. aeruginosa PAO1 with YtnP-ZP1 reduced its swarming motility and elastolytic activity without bactericidal effect. YtnP-ZP1 caused the inhibition of biofilm formation and disintegration of mature biofilms in P. aeruginosa PAO1 and multiresistant clinical strain BR5H that was visualized by crystal violet staining. The treatment with YtnP-ZP1 in concentrations higher than 25 mu g mL(-1) improved the survival of P. aeruginosa PAO1-infected zebrafish (Danio rerio), rescuing 80% of embryos, while in combination with tobramycin or gentamicin survival rate increased to 100%. The treatment of P. aeruginosa PAO1 biofilms on infected zebrafish tail wounds with 50 mu g mL(-1) YtnP-ZP1 and 2 x MIC tobramycin led to infection clearing in 2 days. The extensive toxicity studies proved YtnP-ZP1 was non-toxic to human cells and zebrafish. In conclusion, novel YtnP-ZP1 lactonase with its effective anti-virulence activity could be used to increase the efficacy of clinically approved antibiotics in clearing both systemic and biofilm-associated P. aeruginosa infections.

The treatment with YtnP-ZP1 in concentrations higher than 25 mu g mL(-1) improved the survival of P. aeruginosa PAO1-infected zebrafish (Danio rerio), rescuing 80% of embryos, while in combination with tobramycin or gentamicin survival rate increased to 100%. The treatment of P. aeruginosa PAO1 biofilms on infected zebrafish tail wounds with 50 mu g mL(-1) YtnP-ZP1 and 2 x MIC tobramycin led to infection clearing in 2 days. The extensive toxicity studies proved YtnP-ZP1 was non-toxic to human cells and zebrafish. In conclusion, novel YtnP-ZP1 lactonase with its effective anti-virulence activity could be used to increase the efficacy of clinically approved antibiotics in clearing both systemic and biofilm-associated P. aeruginosa infections.",

AB  - Soils contain microorganisms capable of causing diseases in humans, either
as opportunistic or as obligate pathogens. The application of herbicides
increases the prevalence of antibiotic resistance genes and mobile genetic
elements, which expands the competitive niche of pathogenic microbes. This
implies that herbicides could impose selective pressure driving the spread of
antibiotic resistance and therefore making heavily herbicide treated agricultural
soil a possible reservoir of multiresistant opportunistic human pathogens.
From the soil exposed to chlorinated aromatic herbicides S-metolachlor
and isoxaflutole, semi-persistent selective herbicides widely used in
European Union and Serbia we isolated bacteria able to grow on herbicide as
the sole carbon source. Bacterial isolates were assessed for various virulence
traits and resistance to antibiotics in order to identify the strains with high
pathogenic potential.

AB  - This study investigates the modification of commercial cellulose acetate microfiltration membranes by supercritical solvent impregnation with thymol to provide them with antibacterial properties. The impregnation process was conducted in a batch mode, and the effect of pressure and processing time on thymol loading was followed. The impact of the modification on the membrane's microstructure was analyzed using scanning electron and ion-beam microscopy, and membranes' functionality was tested in a cross-flow filtration system. The antibiofilm properties of the obtained materials were studied against Staphyloccocus aureus and Pseudomonas aeruginosa, while membranes' blocking in contact with bacteria was examined for S. aureus and Escherichia coli. The results revealed a fast impregnation process with high thymol loadings achievable after just 0.5 h at 15 MPa and 20 MPa. The presence of 20% of thymol provided strong antibiofilm properties against the tested strains without affecting the membrane's functionality. The study showed that these strong antibacterial properties could be implemented to the commercial membranes' defined polymeric structure in a short and environmentally friendly process.

AB  - The study reports the application of supercritical solvent impregnation to deliver antibacterial substance thymol to the defined polymeric structure of commercial polyamide microfiltration membranes. The process performed at a temperature of 40 degrees C and pressures of 10, 15, and 20 MPa was characterized by the fast impregnation in the first 30 min with thymol loadings up to 29 wt%. The maximal achieved thymol loading in the process was around 42 wt%, regardless the pressure. The scanning electron and ion microscopy analyses revealed that the membranes' microstructure was preserved with a thymol content of 20 wt%, while a more prominent swelling effect was observed in samples with 35 wt% of thymol. The cross-flow filtration tests showed that the impregnation process did not harm the membranes' functionality in samples with 20 wt% of thymol. These membranes exhibited strong anti-biofilm activity, and were less prone to the blockage with bacteria in comparison to neat membranes.

AB  - The rapid emergence of antibiotic-resistant pathogens presents a global healthcare challenge. Bacteria control their virulence, motility, and biofilm formation, all of them being required for establishing pathogenicity, through a cell density-dependent communication system known as quorum sensing (QS). QS comprises production of extracellular signaling molecules, their detection, and population-wide response involving regulation of the virulence genes expression. Inhibition of QS affects virulence and reduces harmful effects to the host and as such presents a promising strategy to fight antibiotic-resistant infections. Multiresistant Pseudomonas aeruginosa belogns to the group of most critical pathogens for which the introduction of new therapeutics is imperative. In the search for novel therapeutics nature continues to be inexhaustible source of bioactive scaffolds, which provide the bases for structure-based rational drug design enabling further exploitation of diverse natural structures. This review describes bacterial QS systems, highlights strategies for their manipulation, overviews nature-inspired antivirulence molecules primarily against P. aeruginosa, and discusses their perspectives.

AB  - Chokeberry (Aronia melanocarpa) fruit extracts (CE) are rich in polyphenols and usually exhibit immunomodulatory, anti-viral and anti-bacterial effects. We have previously shown that the CE used in this study activated macrophages and stimulated effector T cell differentiation in vitro. When applied orally to healthy mice, CE increased the proportion of CD11c+ dendritic cells in the gut-associated lymphoid tissue. CE-pretreated BALB/c mice readily eradicated orally ingested Listeria monocytogenes as evidenced by a slighter decrease in body weight and number of bacteria recovered from the spleen and reduced spleen size compared to the control infected mice. CE pretreatment in infected mice resulted in higher proportions of CD11b+ macrophages and CD8+ cytotoxic T cells both in the gut and the spleen. Phagocytosis, reactive oxygen species production and the proportions of activated CD86+ macrophages (CD11b+) and dendritic cells (CD11c+) was also enhanced in CE-pretreated infected mice. Further, the expression of inducible nitric oxide synthase and IL-6 was increased in CE-pretreated infected mice and the similar results were obtained in peritoneal macrophages in vitro. This effect of CE was associated with increased phosphorylation of IκB and Notch1 production. Finally, CE pretreatment elevated the proportion of perforin-producing cells in the spleen compared to control infected mice. This study demonstrates that prophylactic treatment with CE leads to more rapid eradication of bacterial infection with Listeria monocytogenes predominantly through increased activity of myeloid cells in the gut and in the spleen.

AB  - Many traditional remedies represent potential candidates for integration with modern medical practice, but credible data on their activities are often scarce. For the first time, the anti-virulence potential and the safety for human use of the ethanol extracts of two medicinal plants, Persicaria maculosa (PEM) and Bistorta officinalis (BIO), have been addressed. Ethanol extracts of both plants exhibited anti-virulence activity against the medically important opportunistic pathogen Pseudomonas aeruginosa. At the subinhibitory concentration of 50 mu g/mL, the extracts demonstrated a maximal inhibitory effect (approx. 50%) against biofilm formation, the highest reduction of pyocyanin production (47% for PEM and 59% for BIO) and completely halted the swarming motility of P. aeruginosa. Both extracts demonstrated better anti-quorum sensing and antibiofilm activities, and a better ability to interfere with LasR receptor, than the tested dominant extracts' constituents. The bioactive concentrations of the extracts were not toxic in the zebrafish model system. This study represents an initial step towards the integration of P. maculosa and B. officinalis for use in the treatment of Pseudomonas infections.

AB  - Infective diseases have become health threat of a global proportion due to appearance and spread of microorganisms resistant to majority of therapeutics currently used for their treatment. Therefore, there is a constant need for development of new antimicrobial agents, as well as novel therapeutic strategies. Quinolines and quinolones, isolated from plants, animals, and microorganisms, have demonstrated numerous biological activities such as antimicrobial, insecticidal, anti-inflammatory, antiplatelet, and antitumor. For more than two centuries quinoline/quinolone moiety has been used as a scaffold for drug development and even today it represents an inexhaustible inspiration for design and development of novel semi-synthetic or synthetic agents exhibiting broad spectrum of bioactivities. The structural diversity of synthetized compounds provides high and selective activity attained through different mechanisms of action, as well as low toxicity on human cells. This review describes quinoline and quinolone derivatives with antibacterial, antifungal, anti-virulent, antiviral, and anti-parasitic activities with the focus on the last 10 years literature.

AB  - Chokeberry (Aronia melanocarpa) fruit extracts (CE) are rich in polyphenols and usually exhibit immunomodulatory, anti-viral and anti-bacterial effects. We have previously shown that the CE used in this study activated macrophages and stimulated effector T cell differentiationin vitro. When applied orally to healthy mice, CE increased the proportion of CD11c(+)dendritic cells in the gut-associated lymphoid tissue. CE-pretreated BALB/c mice readily eradicated orally ingestedListeria monocytogenesas evidenced by a slighter decrease in body weight and number of bacteria recovered from the spleen and reduced spleen size compared to the control infected mice. CE pretreatment in infected mice resulted in higher proportions of CD11b(+)macrophages and CD8(+)cytotoxic T cells both in the gut and the spleen. Phagocytosis, reactive oxygen species production and the proportions of activated CD86(+)macrophages (CD11b(+)) and dendritic cells (CD11c(+)) were also enhanced in CE-pretreated infected mice. Furthermore, the expression of inducible nitric oxide synthase and IL-6 was increased in CE-pretreated infected mice and similar results were obtained in peritoneal macrophagesin vitro. This effect of CE was associated with increased phosphorylation of I kappa B and Notch1 production. Finally, CE pretreatment elevated the proportion of perforin-producing cells in the spleen compared to control infected mice. This study demonstrates that prophylactic treatment with CE leads to more rapid eradication of bacterial infection withL. monocytogenespredominantly through increased activity of myeloid cells in the gut and in the spleen.

AB  - Pseudomonas aeruginosa is one of the most common opportunistic pathogens that use quorum sensing (QS) system to regulate virulence factors expression and biofilm development. Delftia sp. 11304 was selected among 663 Gram-negative clinical isolates based on its QS inhibitory activity against P. aeruginosa MMA83 clinical isolate. Whole genome sequencing identified this isolate as D. tsuruhatensis and revealed genetic armamentarium of virulence factors and antibiotic resistance determinants. Ethyl acetate extract of D. tsuruhatensis 11304 culture supernatant (QSI extract) prevented biofilm formation of P. aeruginosa MMA83, but was unable to cause biofilm decomposition. QSI extract showed a synergistic effect in combination with meropenem and gentamycin, against P. aeruginosa MMA83. A dose-dependent reduction of the virulence factors: elastase, rhamnolipid and pyocyanin production by P. aeruginosa MMA83 and significant downregulation of lasI, lasR, rhlI, rhlR, pqs and mvfR expression were observed. Matrix-assisted Laser Desorption Ionization (MALDI) mass spectrometry of D. tsuruhatensis 11304 QSI extract revealed the presence of N-acyl homoserine lactones (AHL) with chain lengths of C12 to C18. The main ion peak was identified as N-octadecanoylhomoserine lactone (C-18-HSL). Commercial C-18-HSL (20 mu M) reduced pyocyanin production as well as mRNA level of the lasI gene. A novel AHL species, dihydroxy-N-octadecanoylhomoserine lactone, was also described.

AB  - Pseudomonas aeruginosa is a leading cause of nosocomial infections that are becoming increasingly difficult to treat due to the occurrence of antibiotic resistant strains. Since P. aeruginosa virulence is controlled through quorum sensing, small molecule treatments inhibiting quorum sensing signaling pathways provide a promising therapeutic option. Consequently, we synthesized a series of N-octaneamino-4-aminoquinoline derivatives to optimize this chemotype's antivirulence activity against P. aeruginosa via inhibition of pyocyanin production. The most potent derivative, which possesses a benzofuran substituent, provided effective inhibition of pyocyanin production (IC50 = 12 mu M), biofilm formation (BFIC50 = 50 mu M), and motility. Experimentally, the compound's activity is achieved through competitive inhibition of PqsR, and structure-activity data were rationalized using molecular docking studies.

AB  - Ethnopharmacological relevance: Trapa natans L. (water chestnut or water caltrop) is a widespread aquatic plant, which has been cultivated for food and traditional medicine since ancient times. Pharmacological studies showed that water chestnut exhibits the wide range of biological activities, such as antimicrobial, antioxidative, analgesic, anti-inflammatory, as well as antiulcer. Aim of the study: Evaluation of anti-virulence potential and toxicity of T. natans methanol (TnM), acetone (TnA) and ethyl acetate (TnEA) leaf extracts. Materials and methods: The anti-quorum sensing activity of Tn extracts was addressed by measuring their effects on biofilm formation, swarming motility and pyocyanin and elastase production in Pseudomonas aeruginosa. Specific P. aeruginosa biosensors were used to identify which of the signaling pathways were affected. The lethal and developmental toxicity of extracts were addressed in vivo using the zebrafish (Danio rerio) model system. The phenolic composition of T. natans leafs extracts was analyzed by a linear ion trap-OrbiTrap hybrid mass spectrometer (LTQ OrbiTrapMS) and UHPLC system configured with a diode array detector (DAD) hyphenated with the triple quadrupole mass spectrometer. Results: Subinhibitory concentrations of Tn leaf extracts (0.2 MIC) inhibited pyocyanin and elastase production up to 50% and 60%, respectively, and reduced swarming zones, comparing to non-treated P. aeruginosa. TnA inhibited biofilm formation by 15%, TnM showed a stimulatory effect on biofilm formation up to 20%, while TnEA showed no effect. The bioactive concentrations of TnM and TnA were not toxic in the zebrafish model system. Twenty-two phenolic compounds were tentatively identified in TnM, where thirteen of them were identified in T. natans for the first time. Tn extracts, as well as their major components, ellagic and ferulic acids, demonstrated the ability to interfere with P. aeruginosa Las and PQS signaling pathways. Conclusions: This study demonstrates anti-virulence potential of Tn leaf extracts against medically important pathogen P. aeruginosa and confirms the ethnopharmacological application of this plant against microbial infections.

AB  - This study discusses utilization of supercritical carbon dioxide for impregnation of cellulose acetate films with thymol in order to produce material with anti-biofilm activity against Pseudomonas aeruginosa and Staphylococcus aureus. Analysis of anti-biofilm activity of cellulose acetate beads impregnated with thymol suggested that optimal thymol loading was in the range from 26% to 30% for efficient reduction of biofilm formation and eradication of pre-formed biofilms. Polymer films were fabricated by the solvent casting method from polymer solutions of different contents, and loaded with thymol using supercritical carbon dioxide at 15.5 MPa and 35 degrees C. The film containing 30% of thymol (F1 30%) exhibited substantial anti-adhesion properties inhibiting biofilm formation on its surface and considerably reduced formation of biofilms on the surrounding surfaces (up to 80%) by all tested strains including antibiotic resistant P. aeruginosa DM50 and methicillin-resistant S. aureus.

AB  - Pseudomonas aeruginosa has been amongst the top 10 'superbugs' worldwide and is causing infections with poor outcomes in both humans and animals. From 202 P. aeruginosa isolates (n = 121 animal and n = 81 human), 40 were selected on the basis of biofilm-forming ability and were comparatively characterized in terms of virulence determinants to the type strain P. aeruginosa PAO1. Biofilm formation, pyocyanin and hemolysin production, and bacterial motility patterns were compared with the ability to kill human cell line A549 in vitro. On average, there was no significant difference between levels of animal and human cytotoxicity, while human isolates produced higher amounts of pyocyanin, hemolysins and showed increased swimming ability. Non-parametric statistical analysis identified the highest positive correlation between hemolysis and the swarming ability. For the first time an ensemble machine learning approach used on the in vitro virulence data determined the highest relative predictive importance of the submerged biofilm formation for the cytotoxicity, as an indicator of the infection ability. The findings from the in vitro study were validated in vivo using zebrafish (Danio rerio) embryos. This study highlighted no major differences between P. aeruginosa species isolated from animal and human infections and the importance of pyocyanin production in cytotoxicity and infection ability.
