| Popis: | In this study, the susceptibility to cephalosporins of 74 Salmonella isolates, including 16 isolates from farm animals and 58 isolates from poultry was assessed by the disc diffusion method. ESBL production was evaluated by combined disc diffusion method (CDDM) and double disc synergy test (DDST). The genetic relatedness of isolates was investigated by the Rep-PCR method. The highest prevalence of resistance was observed against cefotaxime (27%) and the least – against cefixime (4%). None of the isolates was ESBL positive. The Rep-PCR generated 54 reproducible fingerprint patterns for all isolates and grouped them in four clusters and six singletons. Due to public health risk of cross contamination, it is important to have sufficient information on the occurrence of these resis-tant isolates. |
