M. morganii cells are straight rods, about 0.6–0.7 μm in diameter and 1.0–1.7 μm in length. This organism moves by way of peritrichous flagella, but some strains do not form flagella at 30 °C. M. morganii can produce the enzyme catalase, so is able to convert hydrogen peroxide to water and oxygen.
M. Catarrhalis is an aerobic bacterium that infects the upper respiratory tract and is known to cause pneumonia and bronchitis. This bacterium is also known to be involved in nosocomial infections. M. catarrhalis can be transmitted via infected respiratory droplets and once inhaled, attach to the epithelial cells of the respiratory tract via pili.
Another genus with which they can be confused, especially the species M. catarrhalis, it's with Neisseria, both for its morphology and for the oxidase test.. In this case they are differentiated by the incapacity of the gender Moraxella to form acid from carbohydrates, while most of the Neisseria if they are able to ferment some carbohydrates. Moraxella catarrhalis is an exclusively human commensal and mucosal pathogen. Its role as a disease-causing organism has long been questioned.

Moraxella catarrhalis is an exclusively human commensal and mucosal pathogen. Its role as a disease-causing organism has long been questioned. Today, it is recognized as one of the major causes of acute otitis media in children, and its relative frequency of isolation from both the nasopharynx and t … Vaneechoutte M, Verschraegen G, Claeys G, et al. Respiratory tract carrier rates of Moraxella (Branhamella) catarrhalis in adults and children and interpretation of the isolation of M. catarrhalis from sputum.
M. catarrhalis adheres to mucosal cells with the aid of pili. Infection is believed to result from contiguous spread of the organism from sites of colonization, possibly as a result of the introduction of new, more virulent strains to which the host lacks immunity. M. catarrhalis can often be found in respiratory secretions together with H
Also, the cells express specific proteins that allow uptake for iron which act as receptors. M. catarrhalis causes acute, localized infections such as otitis media, sinusitis, and bronchopneumonia as well as life-threatening, systemic diseases including endocarditis and meningitis. M. catarrhalis also causes a large proportion of cases of lower respiratory tract infections in elderly patients with chronic obstructive pulmonary diseases and chronic bronchitis and frank pneumonia.

A prevalência da colonização por M. catarrhalis depende da idade. Cerca de 1 a 5% dos adultos sadios possuem colonização do trato respiratório superior. A colonização nasofaríngea por M. catarrhalis é comum na infância, pode ser maior nos meses de inverno e é um fator de risco de a otite média aguda; a colonização prévia é um fator de risco de otite média recorrente.

About 1 to 5% of healthy adults have upper respiratory tract colonization. Nasopharyngeal colonization with M. catarrhalis is common throughout infancy, may be increased during winter months, and is a risk factor for acute otitis media; early colonization is a risk factor for recurrent otitis media. モラクセラ・カタラーリス（Moraxella catarrhalis）は、モラクセラ属の細菌の一種で、ヒトの上気道に親和性があり、病原性を示すことの多い菌である。ブランハメラ・カタラーリス(Branhamella catarrhalis)と呼ばれることもある。グラム陰性球菌である。 特徴 M. catarrha lis Nama binomial M or axella catarr h alis M or axella catarrh alis yang sebelum ini disebut Br anha m ella catarr ha lis dan sebelumnya lagi Ne isseria catarrhalis adalah anggota normal flora pada 40 -50% anak -anak sekolah yang sehat.

Young children who are bottle fed are more at-risk due to the possibility of fluid entering the ear. 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. M. catarrhalis is the second most common bacterial cause of worsening COPD.
