Staphylococci form part of the normal flora of humans and a wide variety of animals. Some staphylococcal species also cause infections for human and household pets. The aim of this study was to investigate the prevalence of coagulase-positive staphylococci in humans and dogs within a common household. Coagulase-positive staphylococci could not be identified phenotypically in all cases. Molecular methods were used for the correct identification of pathogenic staphylococci. The prevalence of Staphylococcus aureus was identified in 26/72 (36.1%) dog owners and in 4/61 (6.6%) dogs. Staphylococcus pseudintermedius was isolated from three (4.2%) humans, and from 28 dogs (45.9%). Other coagulase-positive staphylococci species were not isolated in this study. Colonization of S. aureus in humans was significantly higher than in dogs (P < 0.001). Staphylococcus pseudintermedius was more common in dogs compared to humans (P < 0.001). Staphylococcus pseudintermedius strains were isolated from dogs with clinical symptoms more frequently compared to healthy dogs (P = 0.02). Colonization of S. aureus in female dogs was significantly higher compared to male dogs (P = 0.045). The same staphylococci species were isolated from the dog and its owner in six households (12%, 6/50).
