Abstract

Antimicrobial resistance patterns and gene coding for methicillin resistance (mecA) were determined in 25S. aureusand 75 Coagulase Negative Staphylococci (CNS) strains isolates from half-udder milk samples collected from goats with subclinical mastitis. Fourteen (56.0%)S. aureusand thirty-one (41.3%) CNS isolates were resistant to one or more antimicrobial agents.S. aureusshowed the highest resistance rate against kanamycin (28.0%), oxytetracycline (16.0%), and ampicillin (12.0%). The CNS tested were more frequently resistant to ampicillin (36.0%) and kanamycin (6.7%). Multiple antimicrobial resistance was observed in eight isolates, and oneStaphylococcus epidermidiswas found to be resistant to six antibiotics. ThemecAgene was not found in any of the tested isolates. Single resistance against β-lactamics or aminoglicosides is the most common trait observed while multiresistance is less frequent.
