SUMMARY:

The genus Staphylococcus consists of bacteria found on the skin of humans and animals. These commensal microorganisms are functionally categorized into Coagulase-Positive Staphylococci (CPS) and Coagulase-Negative Staphylococci (CNS), and can occasionally cause opportunistic infections. Staphylococcus pseudintermedius and other Methicillin-Resistant Staphylococcus species (MRSP, MRS) are commonly found in the microbiota of healthy dogs. The incidence of community-acquired and healthcare-associated infections caused by MRS, particularly Methicillin-Resistant Staphylococcus aureus (MRSA), is increasing annually. Adoption should be encouraged for families from all social strata when acquiring a pet dog. Living with rescued animals enriches family lives and contributes to the well-being of the dogs themselves. However, home environments can facilitate the exchange of bacterial species between dogs and their owners, along with antimicrobial resistance genes. Through the transfer of genetic elements, bacteria of public health concern may acquire resistance genes.

This study aimed to identify and characterize the beta-lactam resistance profile in 83 Staphylococcus isolates from various species obtained from swabs collected from the body surfaces of dogs available for adoption at the Animal Reception and Monitoring Sector (AMA) of UFRRJ. The goal was to enhance understanding of mecA gene distribution among staphylococcal strains in the canine population at AMA and to investigate the role of Staphylococcus species as reservoirs of this gene in canine microbiota. From a sample of 65 specimens, 83 Staphylococcus isolates were obtained, with 50.6% identified as CPS and 49.4% as CNS, representing 14 distinct species. A total of 21.7% of the isolates harbored the mecA gene. Data analysis revealed the presence of methicillin-resistant isolates among CNS and CPS in the shelter environment, underscoring the need for sanitary surveillance measures and highlighting the importance of a One Health perspective.
