Identification and characterization of staphylococci isolated from cats.

Staphylococcus simulans was found to be the most common staphylococcal species present on the healthy skin and in the nares of cats. S. aureus was the most frequent Staphylococcus species in lesions. Most of the S. aureus strains showed the characteristics of the human ecovar. Other strains isolated formed a heterogenic collection in which not less than 13 species were represented. One of these, S. epidermidis, was almost exclusively associated with lesions. It was concluded that coagulase-positive staphylococci are not endogenous to cats. Staphylococci from other sources, most frequently from man, are often associated with lesions in these animals.
