Transcriptional reprogramming of respiratory tract epithelial cells upon contact with M. catarrhalis is considered to be central to the host defense. The upper airway epithelial cells play a key role together with macrophages, dendritic cells, neutrophils, and mast cells in steering the host inflammatory response against M. catarrhalis .

M. catarrhalis was previously placed in a separate genus named Branhamella. An assessment of the pathogenic significance of M. catarrhalis isolated from a patient in a community practice should take into consideration factors such as the patient'sage, clinical illness, and underlying conditions; the presence of other organisms; and the source of the isolate. Moraxella (Branhamella) catarrhalis was once considered In clinical significance , M.(B.) catarrhalis is characterized in Bergey’s manual as not being of high pathogenicity to man, and usually considered to be a harmless parasite of the mucous membranes of human beings and /or other animals, although most species may be opportunistic pathogens. M. catarrhalis has been shown to synthesize at least three proteins (i.e., UspA1, UspA2, and Hag) that have been classified as trimeric autotransporters and one additional protein that is considered a conventional autotransporter (i.e., McaP) (for reviews, see references 11, 19, and 35). Moraxella catarrhalis is an exclusively human pathogen and is a common cause of otitis media in infants and children, causing 15%-20% of acute otitis media episodes.M. catarrhalis causes an estimated 2-4 million exacerbations of chronic obstructive pulmonary disease in adults annually in the United States.M.

catarrhalis" was recognized as a gram-negative diplococcus, capable of growth at 22°C, whichdisplays certain well-described colonycharacteristics Multibacterial etiology was seen in 34 (38%) samples, and M. catarrhalis was detected in most (85%) of those cases. Fifteen signals for M. catarrhalis were strong, suggesting a highly probable etiological role of the pathogen. [ncbi.nlm.nih.gov] To our knowledge, Moraxella species have been reported as the etiologic agent in three cases Ceftobiprole MIC 50 and MIC 90 values for β-lactamase-positive M. catarrhalis strains (n = 40) were 0.12 μg/ml and 0.5 μg/ml, respectively, whereas the ceftobiprole MIC range for β-lactamase-negative M. catarrhalis strains (n = 9) was ≤0.004 to 0.03 μg/ml. Ceftriaxone MICs usually were generally at least twofold lower than those of ceftobiprole, whereas amoxicillin-clavulanate MICs Moraxella catarrhalis frequently colonises the oropharynges of healthy individuals. Disease is usually limited to the oropharynx, upper airways and lower airways in patients with predisposing conditions. The pathogen rarely causes more invasive disease.

Moraxella catarrhalis is a Gram-negative commensal and pathogenic bacterium found in the human respiratory tract. It is associated with otitis media and

2021-03-22 · Moraxella catarrhalis is a gram-negative, aerobic, oxidase-positive diplococcus that was first described in 1896. The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella.

Of these species the most clinically important are Moraxella catarrhalis, M. lacunata, M. nonliquefaciens, M. osloensis, M. atlantae, and M. phenylpyruvica.. Some strains are unique to animals such asM. bovis, M. canis, M. caprae.In the past these strains were very susceptible to penicillin, however currently there have been cases of Moraxella species producing beta-lactamases.
