Therapy with erythromycin resulted in resolution of symptoms and eradication of the organism. Moraxella (Branhamella) catarrhalis is a gram-negative aerobic coccus commonly found in the nasal mucosa and occasionally associated with a variety ofinflammations (4). It grows readily on commonlaboratory mediaandhas been shown to grow in media containing vitamin-free casein hydrolysate (1). Aprevious study ofthe nutrition ofasingle Branhamella (Neisseria) catarrhalis was recovered from urethral exudates of three men with acute urethritis.

50588 Kuala Lumpur, Malaysia 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. TheB. catarrhalis LPSwerebiologically active, causinglethality in D-galactosamine-sensitized C57/BL6miceandinducingLimulus amoebocyte lysate gelation. Branhamella catarrhalis has long been regarded as an occasional nonpathogenic inhabitant ofthe respiratory tract (22).

Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. The gender Moraxella on Gram stain they can be seen as Gram negative diplobacilli, coccobacilli or diplococci, depending on the species. In the particular case of Moraxella catarrhalis, it is the only species that has a Gram negative diplococcal morphology.

The only species of Branhamella (Branhamella catarrhalis) is reclassified to Moraxella catarrhalis. References.

Gram Stain: Gram-negative with a tendency to resist discoloration. Morphology: Short and plump rods, frequently approaching a coccus shape. Occurring in pairs or short chains. Size: 1.0-1.5 micrometers by 1.5-2.5 micrometers. Motility: Swimming motility is absent but surface bound "twitching" motility may be present.

These colonies were fragile and easy to crumble, and appeared to have a waxy surface. The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc). This tributyrin spot test helped in differentiating M. catarrhalis from other nonpathogenic Neisseria species that are generally found in the respiratory tract. To determine the possible role of Branhamella (formerly Neisseria) catarrhalis as a respiratory pathogen, we screened quality sputa (defined by cellular criteria) that showed numerous gram-negative cocci on Gram's stain for the presence of B catarrhalis. Gram stain of transtracheal aspirate revealed intraleukocytic and extraleukocytic gram-negative diplococci, and a beta-lactamase producing strain of Branhamella catarrhalis was cultured. Therapy with erythromycin resulted in resolution of symptoms and eradication of the organism.

Discovered at the end of the 19th century, Moraxella catarrhalis (formerly Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis) aerobic, asaccharolytic, gram-negative coccobacilli or diplococci that tend to resist decolorization on Gram stain.
