Antimicrobial susceptibility profiles of Staphylococcus spp. from domestic and wild animals

The aim of this study was to determine the prevalence and diversity of veterinary clinical isolates of Staphylococcus and analyze their antimicrobial susceptibility. One hundred Staphylococcus spp. clinical isolates from domestic and wild animals were subjected to partial sequencing of the 16S rRNA gene to species determination. Antimicrobial susceptibility was obtained by a disk diffusion test against six antibiotics: amoxicillin (AMX), cephalexin (LEX), ciprofloxacin (CIP), erythromycin (ERY), gentamicin (GEN) and trimethoprim-sulfamethoxazole (SXT). The most common specie was S. pseudintermedius (61%, 61/100) and resistance to ERY (57%, 57/100), SXT (50%, 50/100) and AMX (46%, 46/100) was detected most frequently. In total, 40% (40/100) of Staphylococcus spp. exhibited a multidrug-resistant (MDR) phenotype. Results of this study emphasize that animals are reservoir of MDR Staphylococcus spp.
