Mycobacterium Mycobacteria are aerobic and nonmotile bacteria (except for the species Mycobacterium marinum, which has been shown to be motile within macrophages) that are characteristically acid fast. Mycobacteria have an outer membrane. They do not have capsules, and most do not form endospores.ycobacterium marinum and perhaps M. bovis have been shown to sporulate; however, this has been contested by further research. The distinguishing characteristic of all Mycobacterium species is that the cell wall is thicker than in many other bacteria, which is hydrophobic, waxy, and rich in mycolic acids /mycolates.

FrequentlyAsked Questions Q: What is MAC? A: “Mycobacterium avium intracellulare” (MAI) or “Mycobacterium avium Complex” (MAC) is an atypical NON-TB germ (micro-organism). MAC is related to the tuberculosis germ, but is not contagious and the MAC microbes live in the environment. It comprises more than one type of microorganism (both M. avium and M. intracellulare). It causes two types of lung disease. One type results in multiple nodules in the lungs and is referred to as “nodular disease”. The second type is associated with cavities in the upper parts of the lung that mimic tuberculosis.

Mycoplasma Mycoplasma is a genus of bacteria that lack a cell wall around their cell membrane.hey can be parasitic or saprotrophic. Several species are pathogenic in humans, including M. pneumoniae, which is an important cause of atypical pneumonia and other respiratory disorders, and M. genitalium, which is believed to be involved in pelvic inflammatory diseases.

Mycobacterium the only genus in the family Mycobacteriaceae of bacteria; slender acid-fast rods which may be straight or slightly curved. They may produce filaments or cocci. The most serious disease caused by members of this genus is tuberculosis. M. fortuitum, M. chelonea, M. marinum are listed as causes of piscine tuberculosis. Other species, including M. aquae, M. kansasii and M. scrofulaceum, may occasionally cause disease in a number of different species. Mycobacterium avium. found mostly in birds but occasionally also in other animals and in humans.

Mycobacterium tuberculosis in Gram Stain (All photos 1000X Magnification). If one examines the cell wall of a Mycobacterium under an electron microscope, it resembles the gram positive cell wall structure. Mycobacteria, however, have a high content of mycolic acid associated with the cell wall which resists staining by the traditional gram stain method.

- Over 60% of the mycobacterial cell wall is lipid. The lipid fraction of MTB's cell wall consists of three major components, mycolic acids, cord factor, and wax-D. Mycolic acids are unique alpha-branched lipids found in cell walls of Mycobacterium and Corynebacterium. They make up 50% of the dry weight of the mycobacterial cell envelope.

Neisseria gonorrhoeae Neisseria gonorrhoeae, also known as gonococcus, or gonococci is a species of gram-negative diplococci bacteria isolated by Albert Neisser in 1879. It causes the sexually transmitted genitourinary infection gonorrhea as well as other forms of gonococcal disease including disseminated gonococcemia, septic arthritis, and gonococcal ophthalmia neonatorum. It is oxidase positive, aerobic, and it survives within neutrophils. To culture, it requires carbon dioxide supplementation and enriched agar wit

Mycobacterium leprae Mycobacterium leprae, also known as Hansen’s bacillus spirilly, mostly found in warm tropical countries, is a bacterium that causes leprosy. It is an intracellular, pleomorphic, acid-fast, pathogenic bacterium. M. leprae is an aerobic bacillus surrounded by the characteristic waxy coating unique to mycobacteria. In size and shape, it closely resembles Mycobacterium tuberculosis. Due to its thick waxy coating, M. leprae stains with a carbol fuchsin rather than with the traditional Gram ...
