“…Two of these isolates were susceptible and one was resistant to penicillin; all were susceptible to amoxicillin-clavulanic acid, chloramphenicol, clindamycin, cephalothin, ceftriaxone, cefotaxime, erythromycin, gentamicin, oxacillin, ampicillinsulbactam, and vancomycin. DISCUSSION Coagulase-positive staphylococci have been recognized as nasal-oral floras in 3 to 72% of various animals (1,4,8,23,34,35). In 1976, Hajek described S. intermedius, a coagulase-positive staphylococcus, previously classified as S. aureus biotypes E and F, which differed from other S. aureus in biochemical reactions and in cell wall composition (20,30).…”

Staphylococcus intermedius in canine gingiva and canine-inflicted human wound infections: laboratory characterization of a newly recognized zoonotic pathogen

Staphylococcal gingival flora was characterized in cultures from 135 dogs. Staphylococcus intermedius was isolated in 39% of the cultures, S. aureus was isolated in 10%, and both were isolated in 2.0%. S. aureus was isolated more often from dogs of working breeds with weights of >40 lb (ca. 18 kg) and with outdoor habitats than was S. intermedius, which was associated with dogs of nonworking breeds with weights of <40 lb and indoor habitats. S. intermedius was distinguished from S. aureus by the following characteristics: coagulation of rabbit plasma at 4 h (26 versus 100%, respectively), hemolysis of sheep blood at 24 h (30 versus 79%, respectively), and mannitol fermentation at 24 h (4 versus 93%, respectively). A clear separation of the two species was apparent only with the acetoin (modified Voges-Proskauer) reaction (100% of the S. aureus isolates versus 0% of the S. intermedius isolates) and P-galactosidase activity on the API Staph-Ident strip (0% of the S. aureus isolates and 100% of the S. intermedius isolates). Susceptibilities of S. intermedius and S. aureus were 72 and 7%, respectively, to penicillin G, and 100% of both species to oxacillin. Fourteen previously collected strains of coagulase-positive staphylococci from infected canine-inflicted human wounds were reanalyzed; 3 of 14 (21 %) isolates were S. intermedius. We conclude that S. intermedius is a common canine gingival flora and is responsible for some canine-inflicted human wound infections, thus representing a newly recognized zoonotic pathogen.
