Antimicrobial resistance of bacterial isolates from sheep and goat cheeses in eastern Slovakia

Pol J Vet Sci. 2021 Mar;24(1):13-22. doi: 10.24425/pjvs.2020.135814.


The aim of this study was to determine prevalence of undesirable bacteria and their antimicrobial profile in samples obtained from a productive farm situated in border region Slanské vrchy (Slovakia), involved in keeping sheep and goats for the purpose of processing raw milk to special products (cheeses). Genus and species identification was carried out by PCR method and MALDI -TOF MS. Isolates thus identified were detected for antimicrobial resistance using the Agar Dilution Method. Bacteria of Staphylococcus spp. exhibited the highest resistance to penicillin (98% isolates). Isolates from the family Enterobacteriacae showed the highest resistance to azithromycin (90%). At the same time, in isolates of Enterococcus spp. we detected high resistance to linezolid (100%). Our investigation showed that all tested strains were resistant to more than one antibiotic used in this study.
