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]
Aquarium granuloma (also known as fish tank granuloma and swimming pool granuloma) is a rare skin condition caused by a non-tubercular mycobacterium known as Mycobacterium marinum. [2] Skin infections with M. marinum in humans are relatively uncommon, and are usually acquired from contact with contaminated swimming pools, aquariums or infected ...
The problem seems minor, but the scratch fails to heal and becomes several lesions, which also spread to her eyeballs. The infection appears to be caused by methicillin-resistant Staphylococcus aureus, but it turns out that she has been infected by Mycobacterium marinum, that she contracted from her aquarium. A middle-aged man suddenly feels as ...
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]
MAC causes disseminated disease in up to 40% of people with HIV in the United States, producing fever, sweats, weight loss, and anemia. [11] [12] [13] Disseminated MAC (DMAC) characteristically affects people with advanced HIV disease and peripheral CD4 cell counts less than 50 cells/uL. Effective prevention and therapy of MAC has the potential ...
Runyon III organisms (nonchromogens) are slow-growing and never produce pigment, regardless of culture conditions. The group includes Mycobacterium avium and Mycobacterium intracellulare (together known as the MAC complex), Mycobacterium ulcerans and numerous other organisms. Mycobacterium xenopi is also a nonchromogen.
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. [10]
The acid-fast staining method, in conjunction with auramine phenol staining, serves as the standard diagnostic tool and is widely accessible for rapidly diagnosing tuberculosis (caused by Mycobacterium tuberculosis) and other diseases caused by atypical mycobacteria, such as leprosy (caused by Mycobacterium leprae) and Mycobacterium avium ...
