AB  - Introduction: Lactolisterin BU (LBU) is a potent bacteriocin derived from Lactococcuslactis subsp. lactis
bv. diacetylactis BGBU1-4. It exhibits antimicrobial properties against Gram-positive food spoilage and
foodborne pathogens. This research aimed to explore the impact of amino acid substitution in LBU on
its antimicrobial activity by utilizing in silico prediction of LBU’ssecondary structure and amino acid substitutions.
Methods: The secondary structure of LBU was predicted using Phyre2 software. Five variants of LBU
were selected and chemically synthesized, along with unaltered LBU and BHT-B,serving as controls. Peptides were twofold diluted in distilled water, resulting in final concentrations ranging from 1000 µg/ml
to 0.5 µg/ml. An agarspot test, employing 5 µl of the dilution, was conducted on three indicatorstrains:
Lactococcus lactis BGMN1-596, Listeria monocytogenes ATCC19111, and Staphylococcus aureus
ATCC25923. The presence of inhibition zones was analyzed after overnight incubation at 37°C (S. aureus)
and 30°C (L. lactis and L. monocytogenes).
Results: Phyre2 analysis unveiled the presence of two α-helices in LBU’s structure. The majority of LBU
variants displayed altered antimicrobial activity, with some changes being genusspecific, potentially attributable to variances in cell wall composition. Some variants completely lost their activity, underscoring the significance of native amino acids or their physicochemical properties in the corresponding
positions within LBU’s structure. Furthermore, it was confirmed that chemically synthesized LBU effectively retains its antimicrobial activity.
Conclusion: Changesin amino acid composition give insight on structure-function relationship of LBU.

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 the
protocol. Quantitative reverse transcription-polymerase chain reaction (RT-qPCR), was used to analyze
the 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 endogenous
control 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. aeruginosa
MMA83 treated with YtnP lactonase were significantly downregulated. The RT -qPCR results show that
treatment with YtnP-lactonase decreased the relative mRNA levels of genes involved in the production
of 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  - Trimethoprim-sulfamethoxazole (SXT) is the preferable treatment option of the infections caused by Achromobacter spp. Our study aimed to analyze the SXT resistance of 98 Achromobacter spp. isolates from pediatric patients, among which 33 isolates were SXT-resistant. The presence of intI1 was screened by PCR and genome sequence analyses. The intI1 gene was detected in 10 of SXT-resistant isolates that had shorter intI1 PCR fragments named intI1S. Structural changes in intI1S were confirmed by genome sequencing and analyses which revealed 86 amino acids deletion in IntI1S protein compared to canonical IntI1 protein. All IntI1S isolates were of non-CF origin. Pan-genome analysis of intI1S bearing A. xylosoxidans isolates comprised 9052 genes, with the core genome consisting of 5455 protein-coding genes. Results in this study indicate that IntI1S isolates were derived from clinical settings and that cystic fibrosis (CF) patients were potential reservoirs for healthcare-associated infections that occurred in non-CF patients.

AB  - Acinetobacter baumanniiis a leading cause of healthcare-associated infections worldwide. Its various intrinsic and acquired mechanisms of antibiotic resistance make the therapeutic challenge even more serious. One of the promising alternative treatments that is increasingly highlighted is phage therapy, the therapeutic use of bacteriophages to treat bacterial infections. Two phages active against nosocomial carbapenem-resistantA. baumanniistrain 6077/12, vB_AbaM_ISTD, and vB_AbaM_NOVI, were isolated from Belgrade wastewaters, purified, and concentrated using CsCl gradient ultracentrifugation. The phages were screened against 103 clinical isolates ofA. baumanniifrom a laboratory collection and characterized based on plaque and virion morphology, host range, adsorption rate, and one-step growth curve. Given that phage ISTD showed a broader host range, better adsorption rate, shorter latent period, and larger burst size, its ability to lyse planktonic and biofilm-embedded cells was tested in detail. Phage ISTD yielded a 3.5- and 2-log reduction in planktonic and biofilm-associated viable bacterial cell count, respectively, but the effect was time-dependent. Both phages produced growing turbid halos around plaques indicating the synthesis of depolymerases, enzymes capable of degrading bacterial exopolysaccharides. Halos tested positive for presence of phages in the proximity of the plaque, but not further from the plaque, which indicates that the observed halo enlargement is a consequence of enzyme diffusion through the agar, independently of the phages. This notion was also supported by the growing halos induced by phage preparations applied on pregrown bacterial lawns, indicating that depolymerizing effect was achieved also on non-dividing sensitive cells. Overall, good rates of growth, fast adsorption rate, broad host range, and high depolymerizing activity, as well as antibacterial effectiveness against planktonic and biofilm-associated bacteria, make these phages good candidates for potential application in combatingA. baumanniiinfections.
