Query: NC_008787:437786 Campylobacter jejuni subsp. jejuni 81-176, complete genome

Lineage: Campylobacter jejuni; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria

General Information: This strain (81-176; Penner serotype 23/36) was isolated during an outbreak of campylobacteriosis in Minnesota, USA, due to the consumption of contaminated milk. This organism is the leading cause of bacterial food poisoning (campylobacteriosis) in the world, and is more prevalent than Salmonella enteritis (salmonellosis). Found throughout nature, it can colonize the intestines of both mammals and birds, and transmission to humans occurs via contaminated food products. This organism can invade the epithelial layer by first attaching to epithelial cells, then penetrating through them. Systemic infections can also occur causing more severe illnesses.

Subject: NC_011896:2240990 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.
