Query: NC_016948:3724390 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_010556:26567 Exiguobacterium sibiricum 255-15, complete genome

Lineage: Exiguobacterium sibiricum; Exiguobacterium; Bacillales Family XII; Bacillales; Firmicutes; Bacteria

General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
