Abstract
Bovine mastitis is the main cause of economic losses in dairy industry. The aim of this study was to determine the prevalence and antibiotic-resistance profile of Staphylococcus aureus and coagulase-negative Staphylococcus spp. isolated from bovine mastitis cases in the municipality of Altonia, northwest region of Parana State, Brazil. Two hundred and forty-eight dairy cows were examined for the presence of mastitis. Milk samples from mastitis cases were collected and analyzed for the presence of Staphylococcus spp. according to the National Mastitis Council (NMC). The antimicrobial susceptibility of the isolates was also evaluated. The results suggest the presence of methicillin-resistant strains in high frequency (20.40%). Hence, the determination of antimicrobial resistance profile is essential to control mastitis in dairy cows. The use of antibiogram may also help to reduce the emergence of multidrug-resistant strains, since the choice of antibiotics will not be based on empirical methodology. Key words: Staphylococcus aureus, coagulase-negative staphylococci, multidrug resistance, methicillin-resistance Staphylococcus aureus.
