M. ulcerans is a mycobacterium, closely related to Mycobacterium marinum which infects aquatic animals and, rarely, humans. [9] It is more distantly related to other slow-growing mycobacteria that infect humans, such as Mycobacterium tuberculosis , which causes tuberculosis , and Mycobacterium leprae , which causes leprosy .

Mayo Clinic researchers found a three-fold increased incidence of cutaneous NTM infection between 1980 and 2009 in a population-based study of residents of Olmsted County, Minnesota. The most common species were M. marinum, accounting for 45% of cases and M. chelonae and M. abscessus, together accounting for 32% of patients. [11]
Mycobacterium ulcerans is a species of bacteria found in various aquatic environments. The bacteria can infect humans and some other animals, causing persistent open wounds called Buruli ulcer . M. ulcerans is closely related to Mycobacterium marinum , from which it evolved around one million years ago, and more distantly to the mycobacteria ...
There is now considerable evidence to suggest that this disease is an infection. Mycobacterium ulcerans has recently been isolated from lesions and is unique to tropical ulcers. [ 5 ] Early lesions may be colonized or infected by, Bacillus fusiformis (Vincent's organism), anaerobes and spirochaetes .
Mycobacterium avium complex (MAC), also called Mycobacterium avium-intracellulare complex, is a microbial complex of three Mycobacterium species (i.e. M. avium, M. intracellulare, and M. chimaera). [6] It causes Mycobacterium avium-intracellulare infection. [7] [8] Some sources also include Mycobacterium avium subspecies paratuberculosis (MAP). [9]
The mission of the CDC expanded beyond its original focus on malaria to include sexually transmitted diseases when the Venereal Disease Division of the U.S. Public Health Service (PHS) was transferred to the CDC in 1957. Shortly thereafter, Tuberculosis Control was transferred (in 1960) to the CDC from PHS, and then in 1963 the Immunization ...
Scabies (also sometimes known as the seven-year itch) is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, variety hominis. The word is from Latin: scabere, lit. 'to scratch'. The most common symptoms are severe itchiness and a pimple -like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually ...
It was formerly known as Mycobacterium balnei. [2] The strain marinum was first identified by Joseph D. Aronson in 1926 and it is observed as a pathogenic mycobacterium [3] causing tuberculosis-like infections in fish (mycobacteriosis) and skin lesions in humans. [3] [4] The bacteria grows optimal at a temperature around 30 °C. [4]
