Moraxella catarrhalis is one of the main causes of middle ear infections in babies and small children. It is also the cause of upper respiratory tract infections, and sometimes pneumonia. Moraxella is common in the winter months and puts babies and children at increased risk for frequent ear infections.

M. catarrhalis AOM is usually considered a relatively less virulent pathogen [10], but the clinical features of AOM caused by M. catarrhalis have not been described in detail. Animal models of M. catarrhalis AOM and human studies have suggested a weaker local immune response and fewer structural changes compared with

Animal models of M. catarrhalis AOM and human studies have suggested a weaker local immune response and fewer structural changes compared with AOM caused by S. pneumoniae or H. influenzae [ 11-13 ]. The prevalence of M. catarrhalis colonization depends on age. About 1 to 5% of healthy adults have upper respiratory tract colonization.

Moraxella catarrhalis, a common inhabitant of the upper respiratory tract, has historically been considered a relatively harmless commensal.Over time, however, this gram-negative coccobacillus has become recognized as the third most common upper respiratory tract pathogen in children and in adults with chronic obstructive pulmonary disease (3, 7, 14, 16). However, M. catarrhalis has emerged as a human pathogen in the last decade [7, 9]. Recently, M. catarrhalis is considered to be the third most common and most important cause of bronchopulmonary infections after Haemophilus influenzae and Streptococcus pneumoniae [10, 11]. Studies have shown that M catarrhalis colonizes the upper respiratory tract in 28-100% of humans in the first year of life.

Some sources recommend that therapy should continue for at least 7 days beyond the resolution of symptoms. 4,8 It would seem prudent to treat the patient for 5 to 7 days after resolution of symptoms. 9 In acute sinusitis, symptoms are present for less than 3-4 weeks and may include the following 13 Jun 2011 catarrhalis should be considered significant in adult patients with lower respiratory tract infections and associated underlying risk factors.

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.

Moraxella catarrhalis frequently colonises the oropharynges of healthy individuals. Disease is usually limited to the oropharynx, upper airways and lower airways in patients with predisposing conditions. The pathogen rarely causes more invasive disease. We present the case of a 65-year-old woman with Crohn’s disease on azathioprine, who was diagnosed with native valve M. catarrhalis

catarrhalis" was recognized as a gram-negative diplococcus, capable of growth at 22°C, whichdisplays certain well-described colonycharacteristics 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 Ceftobiprole MIC 50 and MIC 90 values for β-lactamase-positive M. catarrhalis strains (n = 40) were 0.12 μg/ml and 0.5 μg/ml, respectively, whereas the ceftobiprole MIC range for β-lactamase-negative M. catarrhalis strains (n = 9) was ≤0.004 to 0.03 μg/ml. Ceftriaxone MICs usually were generally at least twofold lower than those of ceftobiprole, whereas amoxicillin-clavulanate MICs Moraxella catarrhalis frequently colonises the oropharynges of healthy individuals. Disease is usually limited to the oropharynx, upper airways and lower airways in patients with predisposing conditions. The pathogen rarely causes more invasive disease.
