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.

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.

hämmas av klavulansyra, liksom enzym av TEM-typ (hos Haemophilus influenzae, gonokocker, Escherichia coli m fl) och SHV-typ (Klebsiella pneumoniae). 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. Moraxella catarrhalis is an emerging human-restricted respiratory tract pathogen that is a common cause of childhood otitis media and exacerbations of chronic obstructive pulmonary disease in adults.

In adults with chronic obstructive pulmonary disease (COPD), M. catarrhalis is now a well-established trigger of approximately 10% of acute inflammatory exacerbations.Although the so-called cold shock response is a well-described bacterial stress response in species such as Escherichia coli, Bacillus subtilis or - more recently - Staphylococcus aureus, M. catarrhalis is the only typical nasopharyngeal pathogen in which this response has been investigated.

Moraxella catarrhalis is an exclusively human commensal and mucosal pathogen. Its role as a disease-causing organism has long been questioned. Today, it is recognized as one of the major causes of acute otitis media in children, and its relative frequency of isolation from both the nasopharynx and t …

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 .
Thermo Scientific Remel Catarrhalis Test Disc is used for rapid detection of butyrate esterase for presumptive identification of Moraxella catarrhalis.
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.
M. catarrhalis är hos barn den vanligaste orsaken till otitis media samt orsakar ihärdig hosta, sinuit och andra luftvägsinflammationer.
