Catarrhalis forms round opaque colonies on blood and chocolate agar, and the colonies can be slid around agar surfaces without being disrupted; this is called the "hockey puck sign". One interesting feature of the cellular structure of M. catarrhalis is the presence of trimeric autotransporter adhesins, which are essentially a type of virulence factor.
