Branhamella catarrhalis has been implicated previously as a cause of bronchopulmonary 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 a human pathogen causing otitis media in infants and respiratory infections in adults, particularly patients with chronic obstructive pulmonary disease. The surface protein Hag (also designated MID) has previously been shown to be a key adherence factor for several epithelial cell lines relevant to pathogenesis by M. catarrhalis, including NCIH292 lung cells, middle gram stain from penicillin disk test-gram negative rods Moraxella species-not M. catarrhalis penicillin disk test performed by evenly streaking a BAP, dropping a 10-unit penicillin disk, incubate, take growth from edge of inhibition zone, gram stain, N. gonorrhoeae and M. catarrhalis will retain coccal morphology while Moraxella species will develop long filamentous or spindle-shaped forms 2020-12-21 Misleading gram stain from a patient with Moraxella (Branhamella) catarrhalis bacteremia. / Das, Kasturi; Shah, Sanjiv; Levi, Michael H. In: Clinical Microbiology 2021-03-22 When M. catarrhalis is grown in the presence of hemin, HumA expression is clearly increased as shown by Western blotting with polyclonal antiserum developed against a HumA peptide. In addition, growth analyses revealed that a HumA-deficient mutant of M. catarrhalis (7169::humA) is restricted for growth in the presence of hemin as the sole iron source compared to the wild-type strain. 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 Study Neisseria and Moraxella Catarrhalis Flashcards at ProProfs - Neisseria and Moraxella Catarrhalis epidemiology, morphology, culture characteristics, diagnostic biochemical tests, and serology. 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 2009-09-01 1987-04-01 2016-08-25 Gram stain: Gram-positive: Microscopic appearance: cocci in grape-like clusters: Oxygen relationship: facultatively anaerobic bacteria: Motility: nonmotile: Catalase test: catalase-positive: Oxidase test: negative* Spores: non-spore forming * Some species (non-human isolates) are positive 2007-06-01 Moraxella catarrhalis is a non-motile Gram-negative diplococcus bacterium that contributed to several human infections including conjunctivitis.

View M. catarrhalis.docx from BIOSCI 383 at University of Wisconsin, Milwaukee. To start the process of determining what my morphological unknown slant #51 was, I prepared a smear to do a Gram stain.

This study aimed to reveal the prevalence of M. catarrhalis in patients who suffered from conjunctivitis in Ahvaz city, southwest of Iran. Results Out of 100 conjunctiva swab specimens, M. catarrhalis was isolated only from one (1% Silver-stained SDS-PAGE patterns of LOS and dLOS from M. catarrhalis strain 26397. Lanes 1 and 2 contain 200 ng each of Salmonella enterica serovar Minnesota LPSs Ra and Rc. Lanes 3 through 6 contain 200, 100, 50, and 25 ng, respectively, of LOS; and lane 7 contains 20 μg of dLOS from M. catarrhalis strain 26397.

They are often referred to as “kidney bean”–shaped diplococci. 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.

cat… M. catarrhalis is easily overlooked in culture because it is phenotypically identical to Neisseria in Gram stain and on culture plates.

Diagnosis • 2015-02-08 2002-01-01 View M. catarrhalis.docx from BIOSCI 383 at University of Wisconsin, Milwaukee. To start the process of determining what my morphological unknown slant #51 was, I prepared a smear to do a Gram stain. Moraxella catarrhalis is a gram-negative, catalase and oxidase positive diplococcus. While it causes otitis media, sinusitis, bronchitis and conjunctivitis in children and adults, it has a tendency to cause lower respiratory tract infections in older ages.

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.
