CHARACTERISTICS: Gram-negative diplococci, aerobic, oxidase +, clinically significant strains usually produce B-lactamase In 1984, B. catarrhalis was reassigned to the genus Moraxella as Moraxella (Branhamella) catarrhalis . This genus now contains both coccoid and rod-shaped bacteria, which are genetically related. This genus now contains both coccoid and rod-shaped bacteria, which are genetically related. Moraxella catarrhalis and Branhamella catarrhalis are homotypic synonyms and it has been suggested that the genus should be divided into two subgenera, Moraxella and Branhamella. The moraxellae are short, plump, Gram-negative rods (1.0–1.5 × 1.5–2.5 µm) that characteristically occur in pairs (particularly those of the subgenus Branhamella). Some strains approach a completely coccal shape. Discovered at the end of the 19th century, Moraxella catarrhalis (formerly Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis) has undergone several changes of nomenclature and changes in status as either a commensal of the upper respiratory tract or a true pathogenic organism of both the upper and lower respiratory Moraxella catarrhalis and Branhamella catarrhalis are homotypic synonyms and it has been suggested that the genus should be divided into two subgenera, Moraxella and Branhamella.

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.

We studied the clinical and laboratory data of four previously reported cases and six additional cases of B. catarrhalis keratitis. Over the past decade, Branhamella catarrhalis has emerged as an important human pathogen.

Catarrhalis forms round opaque colonies on blood and chocolate agar, and the colonies can be slid around agar surfaces without being disrupted; this is called the "hockey puck sign". One interesting feature of the cellular structure of M. catarrhalis is the presence of trimeric autotransporter adhesins, which are essentially a type of virulence factor. Budhani RK, Struthers JK.

Moraxella Symtom - Ludo Stor Gallery from 2021

Moraxella (Branhamella) catarrhalis is now a well-recognized pathogen in lower respiratory tract infections, particularly in the setting of chronic lung disease. The ability to produce beta-lactamase, which now characterizes most clinical strains, appears to be a recently acquired trait. Engelsk definition.
