Gram-negative, oxidase-positive diplococci isolated on selective media that are negative Another genus with which they can be confused, especially the species M. catarrhalis, it's with Neisseria, both for its morphology and for the oxidase test.. In this case they are differentiated by the incapacity of the gender Moraxella to form acid from carbohydrates, while most of the Neisseria if they are able to ferment some carbohydrates. Only oxidase-POSITIVE, catalase-POSITIVE, and gram-NEGATIVE diplococci should be tested with Gonochek -II.
M. catarrhalis was isolated from five different blood culture specimens of the patient. The focus for bacteremia could not be detected. M. catarrhalis reduces both nitrate and nitrite and produces DNAase. A report on the identification of M. catarrhalis in the diagnostic laboratory [14] found that the tests listed above, with the addition of the superoxol test [15], were sufficient to differentiate between M. catarrhalis and morpho-
Moraxella catarrhalis is an important pathogen of humans. It is a common cause of respiratory infections, particularly otitis media in children and lower respiratory tract infections in the elderly.

Penicillinase detection.Thepenicillinase detectiontestwas performedbyusingthe Cefinase reagent (bioMerieux). APINH.TheAPINHsystemprovides13tests: 4fermen-tation tests (glucose, fructose, maltose, and sucrose), 8 In the cases when the bottom agar layer stabbed with the test strains was not treated with catalase, we have observed very extensive, often merging zones of M. catarrhalis strains growth inhibition. Six test strains stabbed uniformly across the agar surface of 9-mm Petri dish completely inhibited the growth of indicator strains.

From these 11 isolates (73.3%) were found positive for a bro-1 gene by RFLP technique whereas 4 isolates (23.7%) were found bro gene negative
M.catarrhalis 本來被歸類在 Neisseria 這一屬但後來科學家仔細研究其 DNAbase、fatty acid、genetic、 transformation之後，發現與 Neisseria 不同所以之後才又被從新命名。 1896年稱為 Mikrokokkus catarrhalis 而後再改為 Moraxella catarrhalis 最後定為 Branhamella catarrhalis 。
Moraxella catarrhalis is a gram-negative diplococcus, formerly known as Neisseria catarrhalis or Branhamella catarrhalis, that is found in the human upper respiratory tract as normal flora and was considered to occasionally cause infections. 1 Currently, M. catarrhalis is a recognized pathogen of upper and lower respiratory tract infections. 2 It has been found as the causative agent in
The catalase test is done by placing a drop of hydrogen peroxide on a microscope slide. An applicator stick is touched to the colony, and the tip is then smeared onto the hydrogen peroxide drop.

Only oxidase-POSITIVE, catalase-POSITIVE, and gram-NEGATIVE diplococci should be tested with Gonochek -II. (See NOTE below.) Note: Kingella species may grow on Modified Thayer-Martin and other selective media. Kingella species are, catalase-negative and can be differentiated from catalase-positive M. catarrhalis and Neisseria species by a Moraxella catarrhalis Performance of the "factor requirement test" for haemophilus involves the inoculation of unsupplemented media with a light suspension of the organism and the placement of X and V factor disks on the agar surface Catalase and oxidase tests were positive, while beta-lactamase activity was negative. The isolate was identified as M. catarrhalis by using API NH (bioMérieux, France) identification strips.
