Moraxella has had a bunch of names over the last century. When it was first discovered it was named Micrococcus catarrhalis, then its name was changed into Neisseria catarrhalis. In fact, previous descriptions of bloody nose syndrome in non-human primates in 1991 [13] and 2002 [2] were attributed to M. (Branhamella) catarrhalis based on colony morphology, Gram stain, and 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 .

In typical Gram stains, M. catarrhalis presents itself as a gram-negative diplococcus with flattened abutting sides. The bacterium has a tendency to resist destaining. The bacterium has a tendency to resist destaining. 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.

1 Jul 2009 Moraxella catarrhalis is an exclusively human pathogen and is a common cause such that these characteristics do not allow one to predict etiology in an Gram-stained smears of sputum samples that contain M. catarrhal

The gender Moraxella on Gram stain they can be seen as Gram negative diplobacilli, coccobacilli or diplococci, depending on the species. In the particular case of Moraxella catarrhalis, it is the only species that has a Gram negative diplococcal morphology.

Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae. It is named after the Swiss ophthalmologist Victor Morax. The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase -positive, and catalase -positive properties.

M. catarrhalis is also known as Branhamella catarrhalis .

Moraxella (Branhamella) catarrhalis, formerly called Neisse-ria catarrhalis or Micrococcus catarrhalis, is a gram-negative, aerobic diplococcus frequently found as a commensal of the upper respiratory tract (124, 126; G. Ninane, J. Joly, P. Piot, and M. Kraytman, Letter, Lancet ii:149, 1997). Over the last 20

The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase -positive, and catalase -positive properties. 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.

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. 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.
