Prevalence of staphylococcal enterotoxins in Staphylococcus pseudintermedius isolates from dogs with pyoderma and healthy dogs.

Abstract

To investigate the role of staphylococcal enterotoxins (SEs) produced by Staphylococcus pseudintermedius in the pathogenesis of pyoderma, isolates from dogs with pyoderma and healthy dogs were analyzed. According to reverse passive latex agglutination, 14/184 isolates (7.6%) from dogs with pyoderma and 9/87 (10.3%) from healthy dogs produced SEs (SEA, SEC or SED). According to multiplex PCR, 99 isolates (53.7%) from dogs with pyoderma and 97 (90.8%) from healthy dogs possessed one or more se genes. There was no significant difference regarding ses between dogs with pyoderma and healthy dogs. Therefore, SEs may not be a direct virulence factor in pyoderma.
