Reports of antimicrobial resistance, including that against methicillin, have increased in strains of coagulase positive Staphylococcus (CPS) isolated from pets, however in Chile this information is limited. Objectives: To determine the antimicrobial susceptibility profiles and to detect the mecA gene in CPS strains isolated from cats in Chile. Materials and Methods: 134 samples were obtained from healthy cats and cats with skin lesions. These strains were characterized in their coagulase production and identified by BBL Crystal kit. The antimicrobial susceptibility was determined by Kirby Bauer method against 12 antimicrobials, including oxacillin. All strains were subjected to PCR to detect the mecA gene. Results: 72 CPS strains were isolated, including S. aureus and S. intermedius. Antimicrobial resistance against at least one drug was detected in s
