Moraxella catarrhalis is a gram-negative pathogen of the middle ear and lower respiratory tract (29, 40, 51, 52, 69, 78).The organism is responsible for ∼15% of bacterial otitis media cases in children and up to 10% of infectious exacerbations in patients with chronic obstructive pulmonary disease (COPD).

Neisseria cinerea is a commensal species grouped with the Gram-negative, oxidase-positive, and catalase-positive diplococci. It was first classified as Micrococcus cinereus by Alexander von Lingelsheim in 1906.

CHARACTERISTICS: Gram-negative diplococci, aerobic, oxidase +, clinically significant strains usually produce B-lactamase 2021-03-22 · Moraxella catarrhalis is a gram-negative, aerobic, oxidase-positive diplococcus that was first described in 1896. The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella. 2020-12-21 · Moraxella catarrhalis (strain RH4) is an emerging human-restricted unencapsulated Gram-negative mucosal pathogen. Long considered to be a commensal of the upper respiratory tract, this bacterium has now firmly been established to be an etiological cause of otitis media (OM) and exacerbations of chronic obstructive pulmonary disease (COPD). Moraxella catarrhalis is the most commonly isolated species and is responsible for cases of acute otitis media (in children older than 3 months old), chronic and serious otitis media (fever, acute ear pain, irritability, and can escalate to sepsis and CNS infection), acute and chronic sinusitis (occasional fever, nasal or postnasal discharge, cough, fetid breath, sinus pain, and headache Isolates of M. catarrhalis were not of prime interest in this study because these isolates can be identified to genus and species using standard laboratory methods. 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.

M. catarrhalis is resistant to amoxicillin and 1st generation cephalosporins. Activity of 2nd generation cephalosporins is variable and may be more bacteriostatic than cidal. Resistance to TMP/SMX increasing. It is generally susceptible to amoxicillin-clavulanate, cefixime, ceftriaxone, tetracyclines, macrolides, and quinolones.
