摘要:Experiment we carried out on the herd of 115 Slovak Pied dairy cows. Were realized three collections of individual milk samples for isolation and identification of coagulase-negative staphylococci (CNS). We collected 341 milk samples. Coagulase - negative staphylococci were isolated in 18.8 % (64). Highest number of CNS we isolated from acute, subclinical, subacute and latent forms of mastitis, respectively. S. warneri (2.88 %), S. chromogenes (17.19 %), S. cohnii (15.63 %) and S. xylosus (14.06 %) was isolated in highest percentage. Was detected presence of 7 virulence factors, include production of staphylococcal enterotoxins, and resistance for antibiotics. S. chromogenes, S. warneri and S. xylosus were detected as most virulent species carrying most virulence factors, and were resistant for most species of tested antibiotics (S. xylosus resistant for N, NV, L, P, E; S. chromogenes, S. sciuri for 4 species of antibiotics). There pathogens were isolated from acute forms of mastitis.
