Query: NC_008611:1015138 Mycobacterium ulcerans Agy99, complete genome Lineage: Mycobacterium ulcerans; Mycobacterium; Mycobacteriaceae; Actinomycetales; Actinobacteria; Bacteria General Information: This organism causes Buruli ulcer and is the third most common mycobacterial pathogen after Mycobacterium tuberculosis and Mycobacterium leprae. The disease has increased dramatically through central and West Africa since the late 1980s. Causative agent of Buruli and Bairnsdale ulcer. Infection by Mycobacterium ulcerans causes the formation of skin ulcers which, if left untreated, can lead to extensive scarring and/or amputation. Mycobacterium ulcerans produces a cytotoxin, mycolactone, which causes the destruction of skin tissue seen in this disease. This organism is resistant to antibiotics and treatment involves the surgical removal of infected tissues.

General Information: This genus comprises a number of Gram-positive, acid-fast, rod-shaped aerobic bacteria and is the only member of the family Mycobacteriaceae within the order Actinomycetales. Like other closely related Actinomycetales, such as Nocardia and Corynebacterium, mycobacteria have unusually high genomic DNA GC content and are capable of producing mycolic acids as major components of their cell wall. Mycobacterium marinum is commonly found in fresh and salt water in North America. This bacterium, a close relative of M. tuberculosis, causes a tuberculosis-like disease in frogs, fish and other cold-blooded animals, and a peripheral granulomatous disease in humans. Human infections can be persistent and may lead to systemic infection and arthritis. M. marinum is photochromogenic, i.e. it produces bright yellow pigmentation (mainly beta-carotene) upon exposure to visible light. Infection is followed by a 2-8 week incubation period resulting in suppuration (pus) and organized ulcerating granulomas (tumorous lesions), predominantly localized in lymphatic and tendon sheaths, and cooler body tissues in the extremities.
