M. catarrhalis was identified on the basis of gram staining, oxidase testing, cefinase and DNAse production, and API NH (bioMérieux). Real-time DNA and RNA polymerase chain reaction (PCR). DNA was extracted using the QIAamp DNA Mini Kit (Qiagen).

2021-02-03 · Mycobacterium smegmatis is a non-motile bacillus, a rod-shaped bacteria 3-5 micrometers long with no means of locomotion. They grow rapidly into a colony called a biofilm, doubling in population through cell division every three to five days. Objective Moraxella catarrhalis is a non-motile Gram-negative diplococcus bacterium that contributed to several human infections including conjunctivitis. This study aimed to reveal the prevalence of M. catarrhalis in patients who suffered from conjunctivitis in Ahvaz city, southwest of Iran. Results Out of 100 conjunctiva swab specimens, M. catarrhalis was isolated only from one (1% Silver-stained SDS-PAGE patterns of LOS and dLOS from M. catarrhalis strain 26397. Lanes 1 and 2 contain 200 ng each of Salmonella enterica serovar Minnesota LPSs Ra and Rc. Lanes 3 through 6 contain 200, 100, 50, and 25 ng, respectively, of LOS; and lane 7 contains 20 μg of dLOS from M. catarrhalis strain 26397.

Branhamella catarrhalis has been implicated previously as a cause of bronchopulmonary infections. Sputum Gram's stain and culture results suggesting significant infection with beta-lactamase-producing strains of B. catarrhalis were correlated with a retrospective chart review of eight pediatric and ten adult patients. Moraxella catarrhalis is an important bacterial cause of otitis media in children and respiratory tract infections in the elderly. Lipooligosaccharide (LOS), a major surface antigen of this bacterium, is a potential vaccine component against the organism. There are three major LOS serotypes (serotypes A, B, and C) in clinical isolates of M. catarrhalis . Our previous studies demonstrated that 2019-01-24 · Moraxella Catarrhalis mainly infect the infants and the young children and ear infections are the most common infections caused by these bacteria.

Moraxella catarrhalis is a gram-negative, catalase and oxidase positive diplococcus. While it causes otitis media, sinusitis, bronchitis and conjunctivitis in children and adults, it has a tendency to cause lower respiratory tract infections in older ages.

M. catarrhalis are Gram-negative diplococci (not diplobacilli) closely resembling Neisseria but are oxidase-positive, fast SUMMARY In recent years, Moraxella catarrhalis has established its position as an important human mucosal pathogen, no longer being regarded as just a commensal bacterium. Further, current research in the field has led to a better understanding of the molecular mechanisms involved in M. catarrhalis pathogenesis, including mechanisms associated with cellular adherence, target cell invasion 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. Branhamella catarrhalis has been implicated previously as a cause of bronchopulmonary infections. Sputum Gram's stain and culture results suggesting significant infection with beta-lactamase-producing strains of B. catarrhalis were correlated with a retrospective chart review of eight pediatric and ten adult patients. Moraxella catarrhalis is an important bacterial cause of otitis media in children and respiratory tract infections in the elderly.

Respiratory tract carrier rates of Moraxella (Branhamella) catarrhalis in adults and children and interpretation of the isolation of M. catarrhalis from sputum. J Clin Microbiol 1990; 28:2674. 2013-12-10 2019-01-29 Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae.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. M. catarrhalis is the clinically most important species under this genus. M. catarrhalis can utilize human transferrin, human lactoferrin, and to some extent human hemoglobin as iron sources, which is mediated by many cell surface iron-binding proteins.
