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

Perfil de suscetibilidade antimicrobiana e diversidade de Staphylococcus spp. de animais domésticos e silvestres

ABSTRACT:

The aim of this study was to determine the prevalence and diversity of veterinary clinical isolates ofStaphylococcus and analyze their antimicrobial susceptibility. One hundredStaphylococcus 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 wasS. 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 MDRStaphylococcus spp.

Key words:
Staphylococcus spp.; antimicrobial resistance; multidrug resistance.
