The aim of this study was to verify the bacterial resistance profile and detect the presence of mecA gene in Staphylococcus spp. isolated from the nasal microbiota of domiciled dogs. For this purpose 100 nasal swabs from 100 domiciled dogs were collected from the central area of the city of Umuarama (PR), along with a questionnaire answered by their owners. After the isolation all Staphylococcus spp. isolates were submitted to the diffusion disc test by the Kirby-Bauer method, and only oxacillin-resistant samples were submitted to the PCR technique to search for the mecA gene and the results were then submitted to statistical analysis to verify possible risk variables. The 100 Staphylococcus spp. and coagulase negative, among which 41 isolates were resistant to oxacillin, no samples were positive for the mecA gene presence, however, 12 resistant to vancomycin were found. It can be concluded that the domiciled dogs are carriers of Staphylococcus spp. multiresistant, being these a possible source of human contamination.
