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. Gram-negative aerobic cocci of low virulence that colonize the nasopharynx and occasionally cause MENINGITIS; BACTEREMIA; EMPYEMA; PERICARDITIS; and PNEUMONIA. Svenska synonymer. Engelska synonymer.

Moraxella catarrhalis (M. catarrhalis) is a type of bacteria that’s also known as Neisseria catarrhalis and Branhamella catarrhalis. Se hela listan på cdc.gov Descrita por primera vez por Ghon y Pfeiffer. Gram: diplococos gram negativo. Catalasa(+).

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. The position of M. catarrhalis in the prokaryotic kingdom is shown in Fig. 1 .

Direct Gram staining of urethral discharge from symptomatic males with urethritis is an important test for gonococcal disease. Moraxella catarrhalis is recognized as a significant pathogen whose isolation from routine sputum cultures is associated with clinical infection. The rapid identification of this organism is important, since most strains produce beta-lactamase and are resistant to penicillin and ampicillin.

Since its discovery at the end of the nineteenth century, Moraxella (Branhamella) catarrhalis has undergone several changes of nomenclature and periodic changes in its perceived status as either a

B. catarrhalis has been most commonly associated with Branhamella catarrhalis (formerly Neisseria catarrhalis) has also been regarded as a normal respiratory commensal, but reports indicate that it can be pathogenic. The role of Neisseria spp was studied in 160 patients with chest infections and symptoms and signs of obstructive respiratory disease. Se hela listan på antimicrobe.org "Branhamella catarrhalis: a Microbiological and Clinical Update," illustrates the rising interest in this organism. Originally described in Germanas Mikrokokkus catarrha-lis byR. Pfeiffer (cited by Frosch and Kolle [125]) and then in English as Micrococcus catarrhalis (e.g., see reference 108), the species was subsequently classified in the genus In 1984, B. catarrhalis was reassigned to the genus Moraxella as Moraxella (Branhamella) catarrhalis .

The rationale for this was that other members of the genus Moraxella are rod-shaped and rarely caused infections in humans. In contrast, true cocci, such as most Neisseria spp. and Moraxella (Branhamella) catarrhalis, with which these organisms may be confused, maintain their original cocci shape in the presence of penicillin. 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.
