AB  - Pseudomonas aeruginosa is a Gram-negative
pathogen responsible for frequent hospital-acquired
infections of the bloodstream, the respiratory
tract, and the urinary tract. Quorum
quenching enzymes are recognized as an alternative
antivirulence approach targeting pathogenic
bacteria. The efficacy of YtnP lactonase in
reducing the virulence of P. aeruginosa MMA83
in vivo using Caenorhabditis elegans as a model
system was investigated. The recombinant YtnP
lactonase exhibits no cytotoxicity, demonstrated
by its lack of harmful effects on both the
immortalized human HaCaT cell line and two
strains of C. elegans (AU37 and N2 wild-type). In
a toxin-mediated killing liquid assay, the survival
rates of C. elegans AU37 mutant and N2 wildtype
strains infected with the clinical isolate P.
aeruginosa MMA83 significantly increased when
pre-treated with YtnP lactonase, compared to
untreated controls. Considering that virulence
factors expression is regulated by quorum sensing
(QS) signaling it is hypothesized that YtnP
lactonase prolongs the life span of C. elegans
by downregulating the QS and expression of
virulence factors of MMA83. The protective effects
of YtnP lactonase against MMA83-induced
pathogenicity in C. elegans, coupled with its absence
of cytotoxicity, position YtnP lactonase as
a promising prophylactic agent with antivirulence
properties.

AB  - Biofilm-associated infections are the main cause of biomaterial implant failure today. The increasing prevalence of antibiotic-resistant pathogens often results in the only solution of implant movement, with serious consequences for patients. Recently, various antimicrobial agents have been recognized as a promising strategy to prevent biofilm formation on implant surfaces. Quorum sensing (QS) plays a central role in the control of bacterial virulence and biofilm formation. The use of quorum quenching (QQ) enzymes to target QS is therefore a promising innovative approach for the development of enzyme-based antivirulence therapeutics, which represent a potential solution to combat infections caused by multidrug-resistant pathogens. This study aimed to characterize the novel YtnP lactonase from the clinical isolate Stenotrophomonas maltophilia 6960 and to investigate its potential to combat the virulence of multidrug-resistant (MDR) Pseudomonas aeruginosa MMA83.

AB  - Infections caused by multidrug-resistant pathogens are one of the biggest challenges facing the healthcare system today. Quorum quenching (QQ) enzymes have the potential to be used as innovative enzyme-based antivirulence therapeutics to combat infections caused by multidrug-resistant pathogens. The main objective of this research was to describe the novel YtnP lactonase derived from the clinical isolate Stenotrophomonas maltophilia and to investigate its antivirulence potential against multidrug-resistant Pseudomonas aeruginosa MMA83. YtnP lactonase, the QQ enzyme, belongs to the family of metallo-β-lactamases. The recombinant enzyme has several advantageous biotechnological properties, such as high thermostability, activity in a wide pH range, and no cytotoxic effect. High-performance liquid chromatography analysis revealed the activity of recombinant YtnP lactonase toward a wide range of N-acyl-homoserine lactones (AHLs), quorum sensing signaling molecules, with a higher preference for long-chain AHLs. Recombinant YtnP lactonase was shown to inhibit P. aeruginosa MMA83 biofilm formation, induce biofilm decomposition, and reduce extracellular virulence factors production. Moreover, the lifespan of MMA83-infected Caenorhabditis elegans was prolonged with YtnP lactonase treatment. YtnP lactonase showed synergistic inhibitory activity in combination with gentamicin and acted additively with meropenem against MMA83. The described properties make YtnP lactonase a promising therapeutic candidate for the development of next-generation antivirulence agents.

AB  - During the past decades several quorum sensing
inhibitors (QSI) of plant origin have been isolated
and chemically characterized. QSI agents
of plant origin represent potential alternative
or complementary approach to antibiotic treatment
of multidrug-resistant bacteria and infections
caused by bacterial biofilms. The aim of
the current study was to screen QSI activities
of horseradish root extracts obtained using
different organic solvents and different root
processing methods (drying at 40°C, 60°C or extraction
of fresh material). Common opportunistic
pathogen Pseudomonas aeruginosa MMA83
was used for QSI screen. RT-qPCR was used to
analyze the effect of the extract on the relative
mRNA levels of the genes QS (lasR, lasI, rhlR, rhlI,
mvfR, pqsH) and the genes involved in P. aeruginosa
MMA83 virulence (lasB, phzM, rhlC, algK,
pvdS). Chemical composition of extracts was
determined by UHPLC Q-ToF MS analysis. The
most active extract obtained using fresh roots
and hexane/ethyl acetate (1:1) solvent mixture
was able to significantly reduce content all examined
mRNA. Qualitative chemical analysis
reviled presence of 15 phenolic acids and their
derivatives, 9 flavonoids and 10 glucosinolates
in majority of examined extracts. It is significant
to emphasize that the most active QSI extract
did not contain a single one, out of ten dominant
glucosinolates, which have undergone to
hydrolysis yielding isothiocyanates and other
sulphur-containing compounds responsible for
QSI effects. Our results strongly indicate that
even mild thermal treatment (40°C) of horseradish
roots prior to extraction could lead to severe
reduction or loss of QSI activity.

AB  - Pseudomonas aeruginosa has been recognized as
a priority pathogen by World Health Organization,
due to the emergence of multidrug-resistant
(MDR) strains. Thus, new treatment options
such as antivirulence strategy is urgently needed.
This strategy is based on the disruption of quorum
sensing (QS) activity of this pathogen. The
focus of this research was to explore the anti-QS
activity of four selected medicinal mushrooms
(Lentinula edodes, Cantharellus cibarius, Trametes
versicolor and Pleurotus ostreatus) extracts on
MDR clinical isolate P. aeruginosa MMA83. Another
aim was to check their cytotoxicity on Caenorhabditis
elegans AU37 (glp-4(bn2) I; sec-1(km4).
Among three types of mushroom extracts - hot
water polysaccharide extracts (WPE), hot alkali
polysaccharide extracts (APE) and methanol
extracts (Met), APE extracts downregulated all
tested QS and virulence factors genes of P. aeruginosa
MMA83. The most prominent effect was
observed for C. cibarius APE extract, lowering
expression from 2-fold (for lasI gene) to 20-fold
for lasB gene. Extracts didn’t show cytotoxic effect
on C. elegans. The efficacy of APE extracts
in lowering the expression of QS and virulence
factors genes of P. aeruginosa MMA83 indicate
that these extracts can reduce pathogenicity of
P. aeruginosa. Also, they possess one of the desirable
biotechnology features – the absence of
cytotoxicity. Anti-QS and antivirulence effect of
APE extracts on P. aeruginosa envisages these extracts
as the promising therapeutic candidates
for the development of next-generation antivirulence
agents.

AB  - Introduction: Quorum quenching (QQ) isthe enzymatic degradation of cell-to-cellsignaling molecules.In this study, the potential of the novel YtnP lactonase, the quorum quenching enzyme derived from S.maltophilia, to reduce P. aeruginosa quorum sensing and virulence factor gene expression was investigated.Methods: MMA83 culture (adjusted to 1.5x105 CFU/ml) was treated with recombinant YtnP lactonase(final concentration 50 μg/ml) at 37°C for 12 hours under aeration. RNA isolation of the treated and untreated MMA83 culture was performed using the RNeasy Mini Kit (Qiagen, Germany) according to theprotocol. Quantitative reverse transcription-polymerase chain reaction (RT-qPCR), was used to analyzethe effect ofYtnP lactonase on the relative mRNA levels of the LasI/LasR, RhiI/RhiR, and PQS signaling network genes of P. aeruginosa MMA83 and virulence factor genes. The rpsL was used as an endogenouscontrol to normalize obtained data following the 2-ΔΔCt method.Results: The QS genes belonging to three QS networks – LasI/LasR, RhiI/RhiR, and PQS of P. aeruginosaMMA83 treated with YtnP lactonase were significantly downregulated. The RT -qPCR results show thattreatment with YtnP-lactonase decreased the relative mRNA levels of genes involved in the productionof elastase (lasB approximately 2-fold), alginate (algK approximately 2.2-fold), pyocyanin (phzM approximately 3.5-fold), pyoverdin (pvdS approximately 2-fold), and rhamnolipid (rhlC approximately 4-fold).These results suggest that YtnP lactonase exerts an antivirulence effect at the transcription level.Conclusion: YtnP lactonase, a quorum quenching (QQ) enzyme, has the potential to be used as an innovative enzyme-based antivirulence therapeutic to combat infections caused by P. aeruginosa.

AB  - Thermal springs represent a habitat with extreme conditions that harbor a unique
microbial community adapted to thrive in this environment. In addition to the geothermal
springs in Iceland, the thermal springs of Vranjska Banja are considered the hottest in
Europe with a water temperature of 63-95°C. Due to global warming and climate change,
there is a growing need for knowledge about the biodiversity of extreme natural habitats.
Besides the exceptional importance of studying extremophilic microorganisms, the
difficulty in their cultivation limits the expanding necessity of research in this field. This
study provides information about the microbial community structure and physicochemical
characteristics of the thermal spring of Vranjska Banja. To determine and monitor the
microbiota diversity of the Vranjska Banja hot spring, for the first time, comprehensive
culture-independent metagenomic analysis in parallel with a culture-dependent
approach was applied. The culture-independent composition of bacterial communities of
the thermal water was investigated using MiSeq-Illumina technology and analyzed by
the computing environment QIIME2 v2021. The applied cultivation approach resulted
in the isolation of 17 strains belonging to genera Bacillus, Anoxybacillus, Hydrogenophilus,
and Geobacillus, based on 16S rRNA sequencing and whole genome sequencing of five
representative strains has been performed. The complete DNA was sequenced using
Illumina HiSeq from the MicrobesNG service. Genomic characterization and OrthoANI
analysis have shown that two of them are candidates for novel species. Products of
extremophilic microorganisms adapted to harsh conditions have great potential to be
used for biotechnological research and industrial application. Results of BAGEL4 and
AntiSMASH showed that the sequenced strains from Vranjska Banja hot spring have
the potential to produce thermostable enzymes (proteases, lipases, amylases, phytase,
chitinase, and glucanase) and various antimicrobial molecules.

AB  - The hot spring Vranjska Banja is the hottest spring on the Balkan Peninsula with a water temperature of 63–95 °C and a pH value of 7.1, in situ. According to the physicochemical analysis, Vranjska Banja hot spring belongs to the bicarbonated and sulfated hyperthermal waters. The structures of microbial community of this geothermal spring are still largely unexplored. In order to determine and monitor the diversity of microbiota of the Vranjska Banja hot spring, a comprehensive culture-independent metagenomic analysis was conducted in parallel with a culture-dependent approach for the first time. Microbial profiling using amplicon sequencing analysis revealed the presence of phylogenetically novel taxa, ranging from species to phyla. Cultivation-based methods resulted in the isolation of 17 strains belonging to the genera Anoxybacillus, Bacillus, Geobacillus, and Hydrogenophillus. Whole-genome sequencing of five representative strains was then performed. The genomic characterization and OrthoANI analysis revealed that the Vranjska Banja hot spring harbors phylogenetically novel species of the genus Anoxybacillus, proving its uniqueness. Moreover, these isolates contain stress response genes that enable them to survive in the harsh conditions of the hot springs. The results of the in silico analysis show that most of the sequenced strains have the potential to produce thermostable enzymes (proteases, lipases, amylases, phytase, chitinase, and glucanase) and various antimicrobial molecules that can be of great importance for industrial, agricultural, and biotechnological applications. Finally, this study provides a basis for further research and understanding of the metabolic potential of these microorganisms.
