In adults, the colonization rate is 1-10.4%. Colonization appears to be Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, m Moraxella Moraxella catarrhalis Another genus of coccobacillary, Gram-negative rods that are usually paired end to end. Some species require enriched media, such as blood or chocolate agar. 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 .

For much of the last century, the bacterium was regarded as a commensal.

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.
