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. <em>S. warneri </em>(2.88 %), <em>S. chromogenes </em>(17.19 %)<em>, S. cohnii </em>(15.63 %) and <em>S. xylosus</em> (14.06 %) was isolated in highest percentage. Was detected presence of 7 virulence factors, include production of staphylococcal enterotoxins, and resistance for antibiotics. <em>S. chromogenes, S. warneri</em> and <em>S. xylosus </em>were detected as most virulent species carrying most virulence factors, and were resistant for most species of tested antibiotics (<em>S. xylosus</em> resistant for N, NV, L, P, E; <em>S. chromogenes, S. sciuri</em> for 4 species of antibiotics). There pathogens were isolated from acute forms of mastitis. </p>}, number={2}, journal={Potravinarstvo Slovak Journal of Food Sciences}, author={Vasiľ, Milan and Elečko, Juraj and Zigo, František and Farkašová, Zuzana}, year={2012}, month={Mar.}, pages={60–63} }
