    Moraxella catarrhalis is a human pathogen with an affinity for the human upper respiratory tract and the middle ear. Other primates, such as macaques, might become infected by this bacterium. [2] Rodents including rats, mice, and chinchillas have been used to study Moraxella catarrhalis with varying degrees of success. [3]

    An indole butyrate disc is used to differentiate between Neisseria gonorrhoeae (negative result) and Moraxella catarrhalis (positive result). This test involves a butyrate disk, which when smeared with a culture, will change color for a positive result after 5 minutes of incubation. A blue color is the result of a positive test.

    Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae. 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. [ 2 ]

    Tributyrin is also used in microbiological laboratories to identify the bacterium Moraxella catarrhalis. [2] Tributyrin is a stable and rapidly absorbed prodrug of butyric acid which enhances antiproliferative effects of dihydroxycholecalciferol in human colon cancer cells. [3]

    Examples of gram-negative diplococci are Neisseria spp. and Moraxella catarrhalis. Examples of gram-positive diplococci are Streptococcus pneumoniae and Enterococcus spp. [10] [11] Presumably, diplococcus has been implicated in encephalitis lethargica. [12] The genus Neisseria belongs to the family Neisseriaceae.

    Chocolate agar showing Francisella tularensis colonies Comparison of two culture media types used to grow Neisseria gonorrhoeae bacteria. Known as overgrowth, the nonselective chocolate agar medium on the left, due to its composition, allowed for the growth of organismal colonies other than those of N. gonorrhoeae, while the selective Thayer–Martin medium on the right, containing ...
