It is named after the Swiss ophthalmologist Victor Morax. The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase-positive, and catalase-positive properties Se hela listan på microbewiki.kenyon.edu Identification of Moraxella species and Morphologically Similar Organisms Bacteriology – Identification | ID 11 | Issue no: 3 | Issue date: 03.02.15 | Page: 2 of 28 UK Standards for Microbiology Investigations | Issued by the Standards Unit, Public Health England Occasionally, they give rise to opportunistic infections in vulnerable patients; in such cases, M. catarrhalis, M. lacunata, M. nonliquefaciens and M. osloensis are most commonly identified.3–5 Moraxella species are gram-negative bacteria and typically appear as short rods and rarely cocci.5 Being pleomorphic and oxidase-positive, the genus Moraxella share these common characteristics with •Gram negative diplococcus •Grows both on blood and chocolate agar media •The colonies are smooth, opaque, gray to white •Oxidase and catalase positive •Asaccharolytic •Produces DNase •Most clinical isolates are beta lactamase positive Moraxella catarrhalis Se hela listan på microbewiki.kenyon.edu Moraxella catarrhalis is a Gram negative bacterium. Thus, after the decolorizer is used, its thin cell wall won't retain the primary stain. The stain is washed away, and Moraxella catarrhalis is Moraxella genus Description –Gram-negative short rods, coccobacilli –Moraxella catarrhalis is diplococci Clinical manifestation Laboratory diagnosis –Gram-negative, diplococci –On blood agar and chocolate agar –Oxidase test –Catalase test –DNAse test –Does it ferment sugar INTRODUCTION. Moraxella catarrhalis is a gram-negative diplococcus that commonly colonizes the upper respiratory tract. It is a leading cause of otitis media in children, acute exacerbations of chronic obstructive pulmonary disease (COPD), and acute bacterial rhinosinusitis.

In the particular case of Moraxella catarrhalis, it is the only species that has a Gram negative diplococcal morphology. 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. The colony remains intact when pushed across the surface of the agar. Moraxella catarrhalis micrograph. Smear made from a colony (blood agar).

Moraxella catarrhalis is a gram negative, diplococcus, aerobic infectious pathogen that is a common cause of upper respiratory, middle ear, and eye infections. It is resistant to many ß-lactam drugs such as penicillin, amoxicillin, and ampicillin.

Moraxella catarrhalis gram stain morphology

Moraxella catarrhalis. Moraxella catarrhalis grows well on blood agar and chocolate agar, producing small, nonhemolytic, grayish-white colonies that slide across the agar surface, like a hockey puck, when pushed with a bacteriologic loop. From: Infectious Diseases (Third Edition), 2010.

Gram-negative diplococci. Morphology suggests pathogenic Neisseria or Moraxella spp. Routine bacterial culture isolated Moraxella catarrhalis.

Colonies of M. catarrhalis may have a rough surface and be friable in consistency, pinkish-brown in color, and opaque. Whereas Neisseria spp. have an optimal growth temperature of 35C-37C, M. catarrhalis strains tolerate lower temperatures and grow well at 28C. 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.

It is a leading cause of otitis media in children, acute exacerbations of chronic obstructive pulmonary disease (COPD), and acute bacterial rhinosinusitis. Incubate and take the growth from the edge of inhibition zone to gram-stain N. gonorrhoeae and M. catarrhalis will retain coccal morphology Moraxella sp.

bacterial isolates were classified according to colony morphology, Gram-stain Streptococcus pneumonia (n = 1) and Moraxella catarrhalis (n = 3) isolates.
