About 1 to 5% of healthy adults have upper respiratory tract colonization. Nasopharyngeal colonization with M. catarrhalis is common throughout infancy, may be increased during winter months, and is a risk factor for acute otitis media; early colonization is a risk factor for recurrent otitis media.

M catarrhalis gram stain

It 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. 2015-08-02 · Gram Stain. The members of the genus Neisseria discussed in this chapter and M. catarrhalis appear as gram-negative diplococci (Figure 40-2) with adjacent sides flattened. They are often referred to as “kidney bean”–shaped diplococci. Se hela listan på hindawi.com Moraxella catarrhalis is a gram-negative diplococcus that colonizes the upper respiratory tract of children.

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.

BSCI 424 — PATHOGENIC MICROBIOLOGY — Fall 2000 Corynebacterium Summary. Gram stain of Corynebacterium spp. demonstrating "Chinese letters" formations. General Overview:. C. diphtheriae and related organisms are collectively termed coryneforms or diphtheroids. Corynebacteria possess capsular (K) and somatic antigens (O)

A Gram smear of sputum and the oxidase test are both used in identifying M. catarrhalis. M. catarrhalis is oxidase positive, indicating that it uses cytochrome c as an electron acceptor. It can be readily grown on either chocolate or blood agar.

M. catarrhalis is a large, kidney-shaped, Gram-negative diplococcus. It can be cultured on blood and chocolate agar plates after an aerobic incubation at 37 °C for 24 hours. Cultures revealed gray-white hemispheric colonies about 1 mm in diameter. These colonies were fragile and easy to crumble, and appeared to have a waxy surface.

Äldre kvinnor med flytning har ofta en gramnegativ flora.

The size of the organism varies; it is often larger than the meningococcus or gonococcus. The flat sides of the organism abut against each other. M. catarrhalis is easily overlooked in culture because it is phenotypically identical to Neisseria in Gram stain and on culture plates. 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.
