Antimicrob Agents Chemother 1998; 42:2521. Brook I. Direct and indirect pathogenicity of Branhamella catarrhalis. M. catarrhalis is the third most common bacterial agent in pediatric acute otitis media and maxillary sinusitis – surpassed only by Streptococcus pneumoniae and Haemophilus influenzae . In adult patients, M. catarrhalis is responsible for acute exacerbations of chronic bronchitis and bronchopneumonia in the elderly and immune compromised ( 41 ). SUMMARY Moraxella catarrhalis (formerly known as Branhamella catarrhalis) has emerged as a significant bacterial pathogen of humans over the past two decades.

M catarrhalis is the third most common cause of otitis media and sinusitis in children (after Streptococcus pneumoniae and Haemophilus influenzae). M catarrhalis is estimated to be responsible for 3-4 million cases of otitis media annually, with an associated health care cost (direct and indirect) of $2 billion each year. 8. Moraxella Catarrhalis is a gram-negative, unencapsulated bacterium that frequently colonizes the human nasopharynx (29, 59).This organism is the third-most-common cause of acute otitis media in infants and very young children and can also cause more serious disease in the respiratory tract of adults, likely being responsible for 2 to 4 million exacerbations of chronic obstructive pulmonary Se hela listan på patient.info Moraxella catarrhalis is a gram negative, diplococcus, aerobic infectious pathogen that is a common cause of upper respiratory, middle ear, and eye infections.

Abstract. Moraxella (Branhamella) catarrhalis is a gram-negative diplococcus that causes upper and lower respiratory tract infections. It is an important cause of otitis media and sinusitis in the young, and of purulent tracheobronchitis and pneumonia in elderly patients who have underlying respiratory pathology. Common antibiotics used to treat M. catarrhalis infections include: amoxicillin-clavulanate ( Augmentin) trimethoprim-sulfamethoxazole (Bactrim) extended-spectrum cephalosporins, such as cefixime (Suprax) macrolides, such as azithromycin (Zithromax) Today, however, B. catarrhalis is recognized as an im- portant human pathogen capable of causing a wide variety of human infec- tions. These include acute otitis media, acute maxillary sinusitis, and bronchopulmonary infections, particu- larly in patients with obstructive pul- monary disease. 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.
