As the tools for defining bacterial genus and species relatedness become more refined, bacterial nomenclature necessarily becomes more complex. 1996-06-01 These 3 letters follow up an editorial on Branhamella catarrhalis (Lancet 1982, i, 1056). The first letter (i) raises the question that treatment of otherwise susceptible pathogens with some β-lactam antibiotics might be compromised by the simultaneous presence of β-lactamase-producing B. catarrhalis. The letter from WARDLE et al. (ii) substantiates this by citing 3 cases in which failure of 2020-05-07 1995-03-01 Branhamella catarrhalis MATERIAL SAFETY DATA SHEET - INFECTIOUS SUBSTANCES SECTION I - INFECTIOUS AGENT NAME: Branhamella catarrhalis SYNONYM OR CROSS REFERENCE: Neisseria catarrhalis, Moraxella catarrhalis CHARACTERISTICS: Gram … Outer membrane protein (OMP) CopB, an iron-repressible 81-kDa major OMP of Moraxella (Branhamella) catarrhalis has been a major focus of investigation.

Moraxella catarrhalis is a bacterium that causes infection by sticking to a host cell. It does this using special proteins called adhesins that are on its outer membrane. Doctors usually treat M

Thepresence of more than 25 squamous epithelial cells indicates that a specimenis unsatisfactory sincethese cells arederivedfrom oropharyngeal mucous membranes (73, 127, 241). Moraxella catarrhalis is a gram-negative unencapsulated diplococcus similar in morphology to the Neisseria. The bacterium was first described by Ghon and Pfeiffer as Micrococcus catarrhalis in 1902 and has since undergone several reclassifications. In 1970 it was placed into the genus Branhamella based on fatty acid content and DNA homology.

Branhamella catarrhalis causes infections ranging from acute, localized infections such as otitis media, sinusitis, and bronchopneumonia to life threatening, systemic diseases including endocarditis and meningitis. B. catarrhalis causes 10-15% of cases of otitis media and a similar proportion of sinusitis. In addition, this organism causes a large proportion of cases of lower respiratory tract infections in elderly patients with chronic obstructive pulmonary disease.

1990-05-14 · Branhamella catarrhalis: Phenotypic Characteristics GARY V. DOERN, PH.D. Worcester, Massachusetts : This review provides a comprehensive description and discussion of recognized phenotypic characteristics of Branhamella catarrhalis: An emphasis is placed on attributes of this organism that are relevant to its recovery and identification in the clinical microbiology laboratory.

1–4 The morphologic and phenotypical To assess the pathogenic significance of Branhamella catarrhalisisolates in patients with respiratory infections and to define the clinical characteristics of such patients. Design and setting Respiratory specimens were assessed in a three‐year prospective study performed in a Brisbane metropolitan hospital. The prevalence of M. catarrhalis colonization depends on age. 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.
