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 (SCC mec ) types. Based on the WGS analysis, MLST, and SCC mec type results, we report for the first time in Argentina two MRSP strains, one each, belonging to ST71-SCC mec III and ST45-ΨSCC mec ₅₇₃₉₅ from 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 SCC mec V found in S. aureus , seven SCC mec V (5C2&5) with two ccr C1 recombinases, and three SCC mec V (5C2) with one ccr C1 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.
