Gram-positive cocci, non-motile, non-spore-forming.
Rounded, opaque colonies, surrounded by double zone hemolysis. Facultatively
anaerobic, 28-37 ºC. Media: Trypticase Soy Yeast extract Agar ± 5% sheep blood,
Trypticase Soy Yeast extract Broth.

Isolated from cat (lungs), dog, horse and parrot specimens. Sensible to novobiocin and polymyxin B. Resistant to deferoxamine.
Uncertain pathogenicity (although coagulase, DN-ase and haemolysins are positive). One report of canine pyoderma in Brasil.
Another S. pseudintermedius strain was isolated from canine purulent skin infection in Romania (admin note).
