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.

15 Mar 2021 The nomenclature of bacteria is complex. Human pathogenic bacteria can be classified according to their characteristics: morphology (cocci,

Micrococcus catarrhalis is a Gram-negative, aerobic diplococcus frequently found Table 1: Laboratory characteristics used in the identification of M .catarrhalis.

Thus, after the decolorizer is used, its thin cell wall won't retain the primary stain. The stain is washed away, and Moraxella catarrhalis is Moraxella genus Description –Gram-negative short rods, coccobacilli –Moraxella catarrhalis is diplococci Clinical manifestation Laboratory diagnosis –Gram-negative, diplococci –On blood agar and chocolate agar –Oxidase test –Catalase test –DNAse test –Does it ferment sugar INTRODUCTION. Moraxella catarrhalis is a gram-negative diplococcus that commonly colonizes the upper respiratory tract. It is a leading cause of otitis media in children, acute exacerbations of chronic obstructive pulmonary disease (COPD), and acute bacterial rhinosinusitis. Incubate and take the growth from the edge of inhibition zone to gram-stain N. gonorrhoeae and M. catarrhalis will retain coccal morphology Moraxella sp. will develop long filamentous or spindle-shaped forms Studies have shown that M catarrhalis colonizes the upper respiratory tract in 28-100% of humans in the first year of life.

M. catarrhalis is the clinically most important species under this genus. Moraxella catarrhalis is a gram-negative cocci that causes ear and upper and lower respiratory infections.

Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. It causes the infection of the host cell by sticking to the host cell using trimeric autotransporter adhesins
