Introduction. Moraxella catarrhalis is classified with the genera Neisseria, Moraxella, Kingella, and Acinetobacter in the family Neisseriaceae.The taxonomic position of M. catarrhalis is currently being debated; it has been proposed that M. catarrhalis be assigned to the genus Moraxella (M. catarrhalis) in the family Moraxellaceae, or to its own genus, Branhamella, in the family Branhamaceae.

There are two specific lactoferrin-binding proteins, LbpA and LpbB, two specific transferrin-binding proteins, TbpA and TbpB, hemoglobin utilization protein, mHuA.

In typical Gram stains, M. catarrhalis presents itself as a gram-negative diplococcus with flattened abutting sides. The bacterium has a tendency to resist destaining. Colonies on blood agar are nonhemolytic, round, opaque, convex, and greyish white.

Direct Gram staining of urethral discharge from symptomatic males with urethritis is an important test Neisseria meningitidis often causes meningitis and meningococcemia; however, meningococcal pneumonia is quite rare. Herein, we report a case of non-invasive meningococcal pneumonia initially misdiagnosed as pneumonia due to Moraxella catarrhalis on the basis of a Gram stain in a 43-year-old woman with asthma, type 2 diabetes mellitus, and schizophrenia. When gram staining M. catarrhalis, the gram stain color would be pink, and the test would be considered gram-negative. Gram negative organisms will stain pink because they have both a cytoplasmic membrane and an outer membrane as well as a thin cell wall (Cowan 2020). Bacterial cell walls are made of a macromolecule called peptidoglycan. Moraxella catarrhalis is a gram negative, diplococcus, aerobic infectious pathogen that is a common cause of upper respiratory, middle ear, and eye infections.

Sputum Gram's stain and culture results suggesting significant infection with beta-lactamase-producing strains of B. catarrhalis were correlated with a retrospective chart review of eight pediatric and ten adult patients. Moraxella catarrhalis is an important bacterial cause of otitis media in children and respiratory tract infections in the elderly.

demonstrating "Chinese letters" formations. General Overview:. C. diphtheriae and related organisms are collectively termed coryneforms or diphtheroids Moraxella catarrhalis är en aerob gramnegativ diplokock som kan orsaka infektioner i luftvägarna, mellanörat, ögat, centrala nervsystemet och i leder hos människor. Bakterien sprids via utandningsluften. Moraxella catarrhalis kan vara resistent mot vissa antibiotika eftersom en del stammar av Moraxella catarrhalis producerar betalaktamas. Moraxella catarrhalis is a gram-negative, catalase and oxidase positive diplococcus.
