Abstract

Bovine mastitis is caused by a variety of pathogens, and treatment of bovine mastitis accounts for the greatest usage of antimicrobials on dairy farms. The possibility of increased resistance caused by usage of antimicrobials for treatment of bovine mastitis is a potential concern for veterinarians. The objective was to describe antimicrobial resistance of gram-positive mastitis pathogens isolated from cases of bovine mastitis.
