Analysis of results of pulsed-field gel electrophoresis revealed 120 episodes of carriage of M. catarrhalis in 50 patients during which a patient acquired a strain and subsequently cleared Confirmation of the diagnosis of M catarrhalis infection is based on culture. Any of a number of antimicrobial drugs may be used to treat M catarrhalis infection, depending on the need for use of oral or parenteral medication, the age of the patient, any underlying conditions present, the sensitivity of the organism, and the desired spectrum of coverage.

catarrhalis resembles commensal Neisseria species in culture and, thus. M. catarrhalis specifically binds the respiratory epithelium and the extracellular matrix of the human upper respiratory tract, and it has been recovered from the biofilms of children with chronic otitis media. 17,18 Although M. catarrhalis does not possess a polysaccharide capsule, it does have a number of surface adhesins. M. catarrhalis is the third leading cause of otitis media after Streptococcus pneumoniae and nontypeable Haemophilus influenzae (21, 34). M. catarrhalis is associated with up to 25% of acute otitis media cases by culture and 46.4% of chronic middle ear effusion cases by PCR . Interestingly, a distant relationship was found between Psychrobacter phenylpyruvicus strain ATCC 23333T (formerly classified as [M.] phenylpyruvica) and [M.] phenylpyruvica strain 752/52, exhibiting less than 96% nucleotide similarity between their 16S rRNA sequences.
In healthy adults the carriage rate is much lower at 1-10%. Carriage rates among those with underlying lung disease and the elderly are higher [ 8 ] . M. catarrhalis-related immunology is a rather confusing area of the literature. M. catarrhalis infections are restricted to mucosal surfaces and are not systemic. Therefore, the correlation between systemic antibody responses and protection against this type of infections is not as straightforward as with systemic infections caused by other
Iron sequestration by the human host is a first line defence against respiratory pathogens like Moraxella catarrhalis, which consequently experiences a period of iron starvation during colonization. We determined the genetic requirements for M. catarrhalis BBH18 growth during iron starvation using t …
M. catarrhalis strains have a high level of homogeneity of outer-membrane proteins. Antibodies to these proteins are usually present in the serum of humans by 4 years of age.

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. SUMMARY Moraxella catarrhalis (formerly known as Branhamella catarrhalis) has emerged as a significant bacterial pathogen of humans over the past two decades. During this period, microbiological and molecular diagnostic techniques have been developed and improved for M. catarrhalis, allowing the adequate determination and taxonomic positioning of this pathogen. M. catarrhalis usually resides in respiratory tract, but can gain access to the lower respiratory tract in patients with chronic chest disease or compromised host defenses, thus causing tracheobronchitis and pneumonia.

Infection is believed to result from contiguous spread of the organism from sites of colonization, possibly as a result of the introduction of new, more virulent strains to which the host lacks immunity. M. catarrhalis can often be found in respiratory secretions together with H 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 Moraxella Catarrhalis for the USMLE Step 1. Remember everything about it, forever.In this video we cover the laboratory and clinical features of Moraxella ca Moraxella catarrhalis is an exclusively human pathogen and is a common cause of otitis media in infants and children, causing 15%-20% of acute otitis media episodes.M. catarrhalis causes an estimated 2-4 million exacerbations of chronic obstructive pulmonary disease in adults annually in the United States.M. catarrhalis resembles commensal Neisseria species in culture and, thus.
