M. catarrhalis is a large, kidney-shaped, Gram-negative diplococcus. It can be cultured on blood and chocolate agar plates after an aerobic incubation at 37 °C for 24 hours. Cultures revealed gray-white hemispheric colonies about 1 mm in diameter. A heightened appreciation for Branhamella catarrhalis as a true pathogen occurred during the 1970s. Presently, Branhamella catarrhalis has been delegated to the genus Moraxella and has been renamed Moraxella catarrhalis. M. catarrhalis on gram stain is a gram-negative diplococcus with a tendency to resist decolorizing . The size of the organism varies; it is often larger than the meningococcus or gonococcus.

Commonly colonizes the URT, particularly in children. For much of the last century, the bacterium was regarded as a commensal. The sputum Gram stain revealed plenty of pus cells and Gram negative diplococci resembling the organism isolated from the thrombus, along with Gram-negative bacilli .
