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_014932:985882 Bartonella clarridgeiae 73, complete genome
Lineage: Bartonella clarridgeiae; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Bartonella clarridgeiae was first identified from a case of cat scratch fever in a veterinarian who had been bitten by a cat. This organism has subsequently been identified in both cats and dogs. Cats, which are infected by fleas carrying the bacteria, in turn infect humans when scratching or biting them, hence the name. A small red bump forms at the site of infection, followed 2-3 weeks later by a painful swelling of the lymph node. In immunocompromized patients, more severe progress may be observed, including encephalitis, swelling of the spleen, and heart valve infection. Approximately 24 000 cases are reported in the US each year.
