Finding bacteria that produce metabolites with antifungal properties may turn out to be invaluable in the fight against this devastating disease. The entomopathogenic bacteria, Xenorhabdus szentirmaii and X. budapestensis produce secondary metabolites that are effective against a wide range of fungal plant pathogens. To assess whether they may also be effective against Bd, we extracted cell-free culture media (CFCM) from liquid cultures of X. szentirmaii and X. budapestensis and tested their ability to inhibit Bd growth in vitro. As a second step, using juvenile common toads ( Bufo bufo ) experimentally infected with Bd we also tested the in vivo antifungal efficacy of X. szentirmaii CFCM diluted to 2 and 10% (v/v), while also assessing possible malign side effects on amphibians. Results of the in vitro experiment documented highly effective growth inhibition by CFCMs of both Xenorhabdus species. The in vivo experiment showed that treatment with CFCM of X. szentirmaii applied at a dilution of 10% resulted in infection intensities reduced by ca. 73% compared to controls and to juvenile toads treated with CFCM applied at a dilution of 2%. At the same time, we detected no negative side effects of treatment with CFCM on toad survival and development. Our results clearly support the idea that metabolites of X. szentirmaii , and perhaps of several other Xenorhabdus species as well, may prove highly useful for the treatment of Bd infected amphibians.}, year = {2023}, eissn = {2191-0855}, orcid-numbers = {Vajna, Balázs/0000-0002-5604-7997} } @article{MTMT:34102891, title = {Exploring the relationship between metal(loid) contamination rate, physicochemical conditions, and microbial community dynamics in industrially contaminated urban soils}, url = {https://m2.mtmt.hu/api/publication/34102891}, author = {Abbaszade, Gorkhmaz and Toumi, Marwene and Farkas, Rózsa and Vajna, Balázs and Krett, Gergely and Dobosy, Péter and Szabó, Csaba and M Tóth, Erika}, doi = {10.1016/j.scitotenv.2023.166094}, journal-iso = {SCI TOTAL ENVIRON}, journal = {SCIENCE OF THE TOTAL ENVIRONMENT}, volume = {897}, unique-id = {34102891}, issn = {0048-9697}, year = {2023}, eissn = {1879-1026}, orcid-numbers = {Vajna, Balázs/0000-0002-5604-7997; Krett, Gergely/0000-0003-1145-4852; Szabó, Csaba/0000-0002-1580-6344; M Tóth, Erika/0000-0001-9048-5758} } @CONFERENCE{MTMT:33127824, title = {Sötét szeptált endofiton gombák szimbionta baktériumai}, url = {https://m2.mtmt.hu/api/publication/33127824}, author = {Vajna, Balázs}, booktitle = {Intézményi ÚNKP Konferencia 2022}, unique-id = {33127824}, year = {2022}, pages = {327}, orcid-numbers = {Vajna, Balázs/0000-0002-5604-7997} } @article{MTMT:32582392, title = {Distribution of bacterial single cell parameters and their estimation from turbidity detection times}, url = {https://m2.mtmt.hu/api/publication/32582392}, author = {Jánosity, Anna and Vajna, Balázs and Kiskó, Gabriella and Baranyi, József}, doi = {10.1016/j.fm.2021.103972}, journal-iso = {FOOD MICROBIOL}, journal = {FOOD MICROBIOLOGY}, volume = {104}, unique-id = {32582392}, issn = {0740-0020}, abstract = {The stochastic growth of homogeneous bacterial populations in the wells of a microtiter plate was studied as a function of the random initial cell number and their random individual lag times. These significantly affected the population growth in the well, while the maximum specific growth rate of the population was constant (or its variance was negligible) for each well. We showed the advantages of the mathematical assumption that a transformation of the single cell lag time, called the single cell physiological state (or, more accurately, that of the sub-population generated by the single cell) follow the Beta distribution. Simulations demonstrated what patterns would such assumption generate for the distribution of the detection times observed in the wells. An estimation procedure was developed, based on the beta-assumption, that resulted in an explicit expression for the expected value of the single cell physiological state as a function of measured "time to detection" values using turbidity experiments. The method was illustrated using laboratory data with Escherichia coli, Salmonella enterica subsp. enterica strains. The results gave a basis to quantify the difference between the studied organisms in terms of their single-cell kinetics.}, year = {2022}, eissn = {1095-9998}, orcid-numbers = {Vajna, Balázs/0000-0002-5604-7997; Baranyi, József/0000-0001-8360-6021} } @CONFERENCE{MTMT:33116623, title = {Endophytic prokaryotes of Dark Septate Endophytic Fungi revealed by NGS metabarcoding}, url = {https://m2.mtmt.hu/api/publication/33116623}, author = {Vajna, Balázs and Knapp, Dániel and Kovács, M.
