It was initially known as Micrococcus or Neisseria catarrhalis and was considered to be a harmless upper respiratory tract commensalft, but subsequently gained 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 resembles commensal Neisseria species in culture and, thus. "Micrococcuscatarrhalis" in 33%ofnasal cultures (9), 18% ofnasopharyngealcultures(112), and46%ofnoseandthroat cultures fromhealthy persons and45%ofsubjects with the commoncold (130). "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.

Treatment is generally empirical and usually includes oral medications (which may be available in liquid formulation) for 10 days. Moraxella catarrhalis is one of the main causes of middle ear infections in babies and small children. It is also the cause of upper respiratory tract infections, and sometimes pneumonia. Moraxella is common in the winter months and puts babies and children at increased risk for frequent ear infections. In the past, M. catarrhalis was considered a nonpathogenic member of the resident flora of the nasopharynx.

2017-03-20 2002-01-01 M. catarrhalis represents a major diagnostic challenge in children with community-acquired pneumonia; the yield of diagnostic tests for M. catarrhalis is low and growth of the pathogen from upper respiratory tract secretions is weak evidence that the organism is the true cause of pneumonia. 32,33 M. catarrhalis bacteremia is reported to occur mainly in children <2 years old, mainly in immunocompetent hosts, … 2011-01-01 Significant hemoptysis is usually treated with bronchial artery embolization, but surgical resection may be considered if embolization is ineffective and pulmonary function is adequate. Superinfection with mycobacterial organisms such as M. avium complex almost always requires multiple drug regimens that include clarithromycin or azithromycin ; rifampin or rifabutin ; and ethambutol .
