Query: NC_009637:602079 Methanococcus maripaludis C7 chromosome, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: Anaerobic methane-producing archeon. This strain was isolated from intertidal salt-marsh sediments. Methanococcus maripaludis is an obligately anaerobic, mesophilic, methane-producing archaeon. Growth on hydrogen and carbon dioxide results in the production of methane as a waste product. M. maripaludis stands out among methanogenic archaea as an ideal model species because of fast reproducible growth and effective genetic tools.
Subject: NC_008601:1658454 Francisella tularensis subsp. novicida U112, complete genome
Lineage: Francisella tularensis; Francisella; Francisellaceae; Thiotrichales; Proteobacteria; Bacteria
General Information: Avirulent species. Francisella novicida is closely related to Francisella tularensis, the causative agent for tularemia but is nonvirulent. This organism, however may cause disease in immunocompromised individuals. They do however cause a disease in mice that is very similar to tularemia. This strain was isolated from water in Utah, USA in 1950. Francisella tularensis is a non-motile, aerobic, rod-shaped Gram-negative bacterium and is the causative agent of tularemia.
