Staphylococcus pseudintermedius is a commensal and opportunistic pathogen of cats and dogs, mostly causing skin and soft tissue infections and post-operative complications. Since its emergence in 1999, the proportions of methicillin-resistant S. pseudintermedius (MRSP) are on an increasing trend in Europe, ranging from 2.0% in Finland, 16.9% in France and up to 33% in Italy , . In addition to being resistant to β-lactams, MRSP also present numerous additional resistances that are impairing antibiotic treatments. Specific lineages of MRSP are disseminating worldwide, with ST71 being the dominant lineage in Europe . In parallel to MRSP, the population structure of methicillin-susceptible S. pseudintermedius (MSSP) isolates is poorly known and only a few studies reported a large genetic diversity , , . This is an obvious knowledge gap since the majority of infections caused by S. pseudintermedius that are still susceptible to methicillin.
