11 Feb 2019 or as in the case of Moraxella catarrhalis, diplococci in morphology, with Introduction • Gram negative bacteria, rod shaped, coccobacilli,

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.

In addition, the organisms discussed in this chapter do not use glucose and most do not grow on MacConkey agar but will grow well on blood and chocolate agar, as well as in commercial blood culture systems. Nonmotile. Colonies are approximately 2.0 mm in diameter in 48 h, opaque, hemispherical, becoming considerably larger and convex, almost flat, on prolonged incubation. They. usually have a friable texture and can be shifted around and picked from the agar.

Moraxella catarrhalis is a gram-negative diplococcus that commonly colonizes the upper respiratory tract. It is a leading cause of otitis media in children, acute exacerbations of chronic obstructive pulmonary disease (COPD), and acute bacterial rhinosinusitis. Dexiang Chen, Vicki Barniak, Karl R.

Neisseria catarrhalis, Moraxella catarrhalis Características Diplococo gram negativo, aeróbico, oxidasa positivo, las especies clínicamente significativas producen beta-lactamasa. 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.

The emergence of the first antibiotic-resistant strain of M. catarrhalis was noted Colony morphology on the BA and CA was nonlytic, round, opaque, convex, and beta-lactamase of Moraxella (Branhamella) catarrhalis,” Antimicrobial A

SYNONYM OR CROSS REFERENCE: Neisseria catarrhalis, Moraxella catarrhalis . 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.
