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.
20 Apr 2018 Background: · fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus. · Can cause infections of the respiratory system (
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 .
Gram stains of expectorated sputum and of transtracheal aspirate revealed gram-negative intracellular and extracellular diplococci. Cultures of these specimens yielded Neisseria catarrhalis.

The bacterium has a tendency to resist destaining. Colonies on blood agar are nonhemolytic, round, opaque, convex, and greyish white. The colony remains intact when pushed across the surface of the agar. Moraxella catarrhalis micrograph. Smear made from a colony (blood agar).
