Colonies of M. catarrhalis may have a rough surface and be friable in consistency, pinkish-brown in color, and opaque. Whereas Neisseria spp. have an optimal growth temperature of 35C-37C, M. catarrhalis strains tolerate lower temperatures and grow well at 28C. moraxella colony morphology on blood agar. Appearance of Moraxella catarrhalis colonies cultivated on sheep blood agar.

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.

av F Jalalvand — pathogens such as H. influenzae, Moraxella catarrhalis, Pseudomonas long been recognized that individual strains differ from one another in morphology and virulence, in the appearance of the colonies which they form, in their ability to

Over the years, the following criteria have been used to unambiguously distinguish M. catarrhalis from other bacterial species: Gram stain; colony morphology; lack of pigmentation of the colony on blood agar; oxidase production; DNase production; failure to produce acid from glucose, maltose, sucrose, lactose, and fructose; growth at 22°C on nutrient agar; failure to grow on modified Thayer-Martin medium; and, finally, reduction of nitrate and nitrite (76, 214).

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. Clinically, these bacteria are known to cause otitis media, bronchitis, sinusitis, and laryngitis.Elderly patients and long-term heavy smokers with chronic pulmonary disease should be aware that M. catarrhalis is associated with bronchopneumonia, as well as exacerbations of existing chronic obstructive pulmonary disease (COPD).

They are strictly aerobic, oxidase-positive, catalase-positive, DNAse-positive and asaccharolytic. Moraxella catarrhalis is now recognized as an important cause of upper and lower respiratory tract infections in children and adults. 2016-09-01 2016-08-25 unambiguously distinguish M. catarrhalis from other bacterial species: Gram stain; colony morphology; lack of pigmentation of the colony on blood agar; oxidase production; DNase pro-duction; failure to produce acid from glucose, maltose, su-crose, lactose, and fructose; growth at 22°C on nutrient agar; It is named after the Swiss ophthalmologist Victor Morax. The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase -positive, and catalase -positive properties.

Moraxella catarrhalis is now recognized as an important cause of upper and lower respiratory tract infections in children and adults. 4. Examine plate for typical colony morphology.

Moraxella spp. are Gram-negative diplococci that morphologically and phenotypically resemble Neisseria spp. They are strictly aerobic, oxidase-positive, catalase-positive, DNAse-positive and asaccharolytic. Moraxella catarrhalis is now recognized as an important cause of upper and lower respiratory tract infections in children and adults.

M. catarrhalis is an exclusively human pathogen, which emphasizes the importance of using human samples to elucidate the immune response to the bacterium. Several surface antigens of M. catarrhalis have been identified as targets of the human immune response, including UspA1, UspA2, CopB, TbpB (OMP B1), LbpB, OMP E, and lipooligosaccharide ( 2 - 5 , 7 , 8 , 16 , 34 , 42 ).
