Query: NC_016948:3023940 Mycobacterium intracellulare MOTT-64 chromosome, complete genome

Lineage: Mycobacterium intracellulare; Mycobacterium; Mycobacteriaceae; Actinomycetales; Actinobacteria; Bacteria

General Information: 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 intracellulare is a member of the Mycobacterium avium complex (MAC). These organisms cause tuberculosis in birds, and pulmonary and disseminated infections in immunocompromized humans. Mycobacterium intracellulare is also an important contributor to MAC-associated pulmonary infections in immunocompetent patients. Infection results in a characteristic pulmonary disease which requires expensive drug therapy for successful treatment. Mycobacterium intracellulare can also be isolated from the environment and, like other environmental organisms, is able to form and survive in biofilms.

Subject: 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.
