Occurrence of Resistant Staphylococcus Spp. Strains in Animal Rearing
The aim of study was the prevalence of Staphylococcus spp. and their methicillin-resistant strains in livestock
rearing. We have investigated 1,982 samples from dairy cows farms, 94 from suckler cows, 68 from goat, 354 from sheep
and 81 samples from pig rearing. All strains identified as Staphylococcus spp. were analysed by PCR method for detection
of the mecA gene. S. aureus was the most frequent species in each type of farming (28.3% in total), then S. epidermidis
(4.8%), S. chromogenes (3.5%), S. warneri (3.2%), S. haemolyticus (2.6%), S. xylosus (2.3%). The incidence of MRSA was
confirmed in dairy cows and goat´s farms (4.9% and 18.3% respectively), methicilin resistant S. hyicus in dairy cows (50%).
Among CNS, there were isolated S. epidermidis in dairy cow´s, goat´s and sheep farms (41.2%, 35% and 60%, respectively),
then S. haemolyticus (20%), S. chromogenes (13.7%) and S. equorum (21.9%) in dairy cows.
