Abstract
OBJECTIVE: spp. causing acute clinical mastitis and their pattern of antibiotic resistance in dairy cows. MATERIALS AND METHODS: spp. isolates. RESULTS: genes). Age, parity number, cleaning of bedding materials, cleaning of milking facilities, and utensils and udder cleaning practice were significant risk factors for multidrug-resistant streptococcal mastitis in dairy cows. CONCLUSION: antibiotic-resistant genes were identified in streptococci isolates from dairy cows' milk with acute clinical mastitis, indicating a public health hazard. Thus, veterinary clinical breakpoints are needed to improve surveillance data, improve the hygiene regimen on the farms, and promote the wise use of antimicrobials.
