(128) showed that colony morphology, Gram stain, and oxidase production were an insufficient group of characteristics to permit correct and final identification of M. catarrhalis in cultures derived from sputum samples. The prevalence of M. catarrhalis colonization depends on age.

Moraxella catarrhalis. [ 1 ] It is a common commensal organism of the upper respiratory tract, particularly in children; however, it is increasingly being recognised as a pathological organism causing otitis media, sinusitis, ocular infection and occasionally laryngitis. Background. Cultural characteristics. Moraxella catarrhalis is an exclusively human commensal and mucosal pathogen. INTRODUCTION.

Moraxella (Branhamella) catarrhalis, formerly called Neisseria catarrhalis or Micrococcus catarrhalis, is a gram-negative, aerobic diplococcus frequently found as a commensal of the upper respiratory tract (124, 126; G.

Summary Since its discovery at the end of the nineteenth century, Moraxella (Branhamella) catarrhalis has undergone several changes of nomenclature and periodic changes in its perceived status as either a commensal or a pathogen. Moraxella catarrhalis (formerly Branhamella catarrhalis) is a diplococcus [30] found as normal flora in the nasopharynx of NHPs and humans, but it has been implicated in outbreaks of epistaxis (bloody nose syndrome) in both immunocompetent and immunosuppressed macaques [148, 149]. catarrhalis, N. ovis and N. caviae to ibfordxella, or, alternatively, creation of a new genus for these species. Ecology. Introduction.
Moraxella catarrhalis is specifically a human pathogen and it can cause infection in immunocompromised hosts, such as HIV/AIDS patients.

[ 1 ] It is a common commensal organism of the upper respiratory tract, particularly in children; however, it is increasingly being recognised as a pathological organism causing otitis media, sinusitis, ocular infection and occasionally laryngitis.

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. It is a leading cause of otitis media in children, acute exacerbations of chronic obstructive pulmonary disease (COPD), and acute bacterial rhinosinusitis. 8.1 Pregnancy. Abstract.
