Samples were collected from secretion of their skin lesions and right nostril, cultured, and analyzed for phenotypic and genotypic characteristics of the bacteria studied. In 62 samples (91%) the microorganism was classified as S. pseudintermedius. The rate of resistance against antibiotics ranged from 7% (amikacin; 4/62) to 77% (sulfamethoxazole + trimethoprim; 48/62). Resistance against oxacillin was found in 34% of the samples (21/62). Twenty-five samples (37%) were strains that carried the mecA gene. A significant correlation (P<0.01) was found between presence of the mecA gene and oxacillin resistance. Seventeen dogs were mecA gene carriers, and 8 (47%) of them had the gene in the skin lesions and nostril. A significant correlation (P<0.01) was also observed between the presence of mecA gene in the skin lesions and nostrils. Oxacillin resistance in vitro can be safely used to indicate the presence of mecA gene in MRSP samples. The nostrils can be a reservoir of MRSP in dogs.Para acessar a prevalência de MRSP na pele e nas narinas de cães com piodermite superficial, determinar a suscetibilidade in vitro, e correlacionar estes dados com a presença do gene mecA, foram selecionados 43 cães. Amostras de lesões de pele e narinas foram coletadas, cultivadas, e analisadas fenotipica e genotipicamente. Em 62 amostras (91%), os microrganismos foram classificados como Staphylococcus pseudintermedius. A taxa de resistência a antibióticos variou entre 7% (amicacina; 4/62) e 77% (sulfamethoxazol + trimetoprim; 48/62). Resistência a oxacilina foi observada em 34% das amostras (21/62). Vinte e cinco amostras (37%), eram cepas portadoras do gene mecA. Correlação significativa (P<0,01) foi observada entre a presença do gene mecA e a resistência à oxacilina. Considerando os cães, 17 eram portadores de cepas com gene mecA e 8(47%) delas carreavam este gene nas amostras de lesão de pele e nas narinas. Correlação significativa (P>0,01) foi observada entre a presença do gene mecA nas lesões de pele e nas narinas. Sendo assim, resistência à oxacilina in vitro pode ser aferida com segurança para indicar a presença do gene mecA em amostras de MRSP, e as narinas podem constituir em um reservatório dos microorganismos em cães.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisengUniversidade Federal de Minas GeraisUFMGBrasilVET - DEPARTAMENTO DE CLÍNICA E CIRURGIAVET - DEPARTAMENTO DE MEDICINA VETERINÁRIA PREVENTIVAPesquisa Veterinária BrasileiraDermatopatiasStaphylococcusInfecções estafilocócicasAntibacterianosOxacilinaCãesSkin diseaseStaphylococcus pseudintermediusStaphylococcal infectionsAntibioticsOxacillinMecAMRSPDogsPrevalence and in vitro susceptibility of methicillin-resistant Staphylococcus pseudintermedius (MRSP) from skin and nostrils of dogs with superficial pyodermaPrevalência e suscetibilidade in vitro de Staphylococcus pseudintermedius resistente à meticilina (MRSP) oriundos de pele e narinas de cães com piodermite superficialinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/pvb/a/xcFsBst55VCQR6JcynFwnYt/?lang=en#Larissa Silveira BotoniCarolina Boesel SchererRodrigo Otavio SilvaFernanda M.
