Methicillin-resistant Staphylococcus pseudintermedius: an underestimated risk at pet clinic | Staphylococcus pseudintermedius meticilina-resistente: um risco subestimado na clínica de animais de companhia

Английский. The prevalence of methicillin-resistant Staphylococcus pseudintermedius (MRSP) as a cause of infectious disease in companion animals remains unknown. The emergence of MRSP is a challenge in veterinary medicine as multidrug-resistant strains began to emerge, resulting in treatment failures. This study provides an overview of the characterization of S. pseudintermedius strains from clinical pet samples and the prevalence of MRSP strains. A total of 123 S. pseudintermedius strains were characterized by phenotypic testing and the MALDI-TOF technique and evaluated for susceptibility to methicillin and the presence of the mecA gene. Of these, 49 (39.8%) were identified as MRSP. The results confirm the importance of monitoring resistant pathogens and the need for further studies to determine the prevalence of MRSP in companion animals.

португальский. A prevalência de Staphylococcus pseudintermedius (MRSP) resistente à meticilina como causadores de doenças infecciosas em animais de companhia permanece desconhecida. O surgimento de MRSP é um desafio na medicina veterinária, já que cepas resistentes a múltiplas drogas começaram a surgir, resultando em falhas no tratamento. Este estudo fornece uma visão geral sobre a caracterização de cepas de S. pseudintermedius oriundas de amostras clínicas de animais de companhia e a prevalência de cepas de MRSP. Um total de 123 cepas de S. pseudintermedius foram caracterizados através de provas fenotípicas e pela técnica de MALDI-TOF e avaliadas quanto à suscetibilidade à meticilina e à presença do gene mecA. Destas, 49 (39.8%) foram identificados como MRSP. Os resultados confirmam a importância do monitoramento de patógenos resistentes e a necessidade de mais estudos para determinar a prevalência de MRSP em animais de companhia.
