Moraxella (Branhamella) catarrhalis bacteremia in an immunocompetent children
Moraxella catarrhalis is an aerobic, Gram-negative diplococcus that commonly inhabits the upper respiratory tract (1). M. catarrhalis is now considered as an important cause of respiratory tract infections in children and adults with chronic obstructive pulmonary disease (COPD) (2, 3, 4). M. catarrhalis is now considered a common cause of otitis media in children and sinusitis in both children ...
متن کاملBranhamella catarrhalis
A modified oxidation-fermentation medium was developed as a practical medium for highly sensitive and specific detection of acid production from carbohydrates by Neisseria spp. and Branhamella catarrhalis. A total of 756 strains representing 17 Neisseria spp. and Branhamella catarrhalis were tested in this medium, in which the protein concentration was reduced relative to the carbohydrate conce...
متن کاملAntigenic heterogeneity and molecular analysis of CopB of Moraxella (Branhamella) catarrhalis.
Outer membrane protein (OMP) CopB, an iron-repressible 81-kDa major OMP of Moraxella (Branhamella) catarrhalis has been a major focus of investigation. To assess CopB as a potential vaccine antigen, we elucidated the degree of antigenic and sequence heterogeneity in this protein among strains of M. catarrhalis. Two monoclonal antibodies, 1F5 and 2.9F, which bind to surface-exposed epitopes on C...
متن کاملComparison of restriction enzymes for pulsed-field gel electrophoresis typing of Moraxella catarrhalis.
NotI, the most prevalent restriction enzyme used for typing Moraxella catarrhalis, failed to digest genomic DNA from respiratory samples. An improved pulsed-field gel electrophoresis (PFGE) methodology determined SpeI as the best choice for typing this bacterial species, with a good restriction of clinical samples and a good clustering correlation with NotI.
متن کاملBranhamella catarrhalis respiratory infections.
Branhamella catarrhalis is an aerobic Gram-negative diplococcus. It has been traditionally regarded as an oropharyngeal commensal and until recently was only identified as a pathogen in cases of bronchopulmonary infections. The aim of this study was to analyse the characteristics of the respiratory infections caused by B. catarrhalis and to know the antibiotic susceptibility of this microorgani...
