Moraxella catarrhalis is a common inhabitant of the human upper respiratory tract and is an opportunistic pathogen associated with otitis media in infants and children and lower respiratory tract infection in adults with chronic obstructive pulmonary disease ( Murphy, 1996; Murphy and Parameswaran, 2009 ).
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. M. catarrhalis is an aerobic, gram-negative diplococcus that grows well on blood or chocolate agar. The organism is oxidase positive, nitrate negative, and demonstrates
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.

Moraxella catarrhalis is an exclusively human commensal and mucosal pathogen. Its role as a disease-causing organism has long been questioned.

Multibacterial etiology was seen in 34 (38%) samples, and M. catarrhalis was detected in most (85%) of those cases. Fifteen signals for M. catarrhalis were strong, suggesting a highly probable etiological role of the pathogen. [ncbi.nlm.nih.gov] To our knowledge, Moraxella species have been reported as the etiologic agent in three cases

Högt LPK, Högt CRP. Haemophilus influenzae, Moraxella catarrhalis In patients with chronic obstructive pulmonary disease (COPD), Moraxella catarrhalis infection of the lower airways is associated with chronic colonization and Moraxella catarrhalis is frequently colonizing the human respiratory tract, particularly in children.
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.
