Very small white, opaque and glistening colonies (0.2-0.5 and 0,2-1,0 mm in diameter after 24 and 48 h, respectively) with β-hemolysis (clear hemolysis) on e.g. bovine, equine and sheep blood agar.

Pyolysin, which lyse cells (cytolytic activity) of the host by forming transmembrane pores. Neuraminidases, adhesion factors like fimbriae, and ability to form biofilm, which all contribute to the colonization of the host tissues.
