Plain-English summary
A group of dogs in Argentina with skin infections called pyoderma were found to have a type of bacteria known as methicillin-resistant Staphylococcus pseudintermedius (MRSP). Researchers identified two specific strains of this bacteria that had not been reported in the country before. These strains can be particularly concerning because they are resistant to common antibiotics, making infections harder to treat. This study highlights the importance of monitoring these bacteria to protect the health of pets and prevent potential infections in humans.

Abstract
Staphylococcus pseudintermedius is an opportunistic pathogen commonly associated with skin infections in dogs. Twenty-three methicillin-resistant S. pseudintermedius (MRSP) isolated in Argentina from dogs with pyoderma were analyzed using whole genome sequencing (WGS) and classified into sequence types (ST) by multilocus sequence typing (MLST) and staphylococcal chromosome cassette mec (SCCmec) types.Based on the WGS analysis, MLST, and SCCmec type results, we report for the first time in Argentina two MRSP strains, one each, belonging to ST71-SCCmec III and ST45-ΨSCCmecfrom dogs with pyoderma. We also identified seven isolates with ST339, which had been previously reported in only two isolates in Argentina. Additionally, we identified ten MRSP isolates harboring variants of the SCCmec V found in S. aureus, seven SCCmec V (5C2&5) with two ccrC1 recombinases, and three SCCmec V (5C2) with one ccrC1 recombinase.Our findings provide important insights into the evolution and geographic spread of these hypervirulent dominant clones that threaten the health of our companion animals and represent a significant risk for zoonotic infections.
