Query: NC_009077:4671417 Mycobacterium sp. JLS, complete genome

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

General Information: This organism was isolated from creosote-contaminated soil from the Champion International Superfund site in Libby, Montana, USA. This microbe, along with some others collected at this site, is able to rapidly mineralize 14C-labeled pyrene. Phylogenetic studies based on the rRNA 16S gene confirmed that strains collected at this site were distinct from one another and also from other known Mycobacterium isolates.

Subject: NC_011896:332939 Mycobacterium leprae Br4923, complete genome

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

General Information: This strain was isolated from a human skin biopsy in Brazil, and passaged in nude mice and armadillos. The bacterium is a close relative of M. tuberculosis. However, compared to the latter, the genome of M. leprae is smaller due to reductive genome evolution, with many important metabolic activities including siderophore production, part of the oxidative chain, most of the microaerophilic and anaerobic respiratory chains, and numerous catabolic systems and their regulatory circuits eliminated due to extensive recombination events between dispersed repetitive sequences. It is evident that this species has undergone massive genome reduction over time as a result of its parasitic nature, discarding more than half its genes and rendering it the most striking example of genome reduction in a microbial pathogen.
