The experiment was carried out in two herds of the breed of sheep, Improved Valaska, in the Slovakia region. Eleven species of the genus <em>Staphylococcus</em> spp. (n = 431) were isolated and taxonomically identified. From the coagulase-positive staphylococci (CPS), <em>S. aureus</em> was isolated during the reporting period, however, most often in the third year (50). The incidence of <em>S. intermedius</em> and <em>S. hyicus</em> were irregular. The incidence of <em>S. schleiferi</em> was highest at the end of the follow-up duration. From the coagulase-negative staphylococci (CNS) (n = 158), were isolated <br /><em>S. epidermidis</em> present in 20.4% (88) and <em>S. chromogenes</em> 11.4 % (49), <em>S. caprae, S. xylosus,</em> and other species rarely occurred. <em>S. aureus</em> (n = 133) showed maximum resistance to erythromycin 12.0%, novobiocin 10.5%, and neomycin 9.0%. The incidence of intermedial susceptibility was observed predominantly to a penicillin (16 strains), novobiocin (11 strains), erythromycin (14 strains), oxacillin, and cloxacillin (12 strains), neomycin (11 strains), and lincomycin (9 strains). Observantly, <em>S. schleiferi</em> (n = 101) showed the highest resistance to novobiocin (5.9%) and erythromycin (5.0%), however, a high incidence of intermediate susceptibility to erythromycin (9), amoxicillin, novobiocin (8), ampicillin, lincomycin (7), penicillin, methicilin and cefoperazone (5 strains) can be identified as adverse. The incidence of resistant and intermediate sensitive test strains <em>S. aureus</em> and <em>S. schleiferi</em>, especially for erythromycin, novobiocin, and neomycin, which are often used to treat udder inflammation in sheep, is relatively adverse.</p> ER -
