Query: NC_015474:644552 Pyrococcus sp. NA2 chromosome, complete genome
Lineage: Pyrococcus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Pyrococcus has similar characteristics of other thermoautotrophican archaea such as Archaeoglobus, and Methanococcus in the respect that they are all thermophilic and anaerobic. Pyrococcus differs, however, because its optimal growth temperature is nearly 100 °C and dwells at a greater sea depth than the other archaea. Studying Pyrococcus helps give insight to possible mechanisms used to endure extreme environmental conditions like high temperatures and high pressure.
Subject: NC_013798:345339 Streptococcus gallolyticus UCN34, complete genome
Lineage: Streptococcus gallolyticus; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Isolated from a human case of endocarditis associated with colon cancer in Caen, France in 2001. Streptococci are non-motile, Gram-positive cocci with widely varying pathogenic potential that occur in pairs or chains. Streptococcus gallolyticus (strain UCN34, biotype I) is a commensal Gram-positive bacterium isolated from various habitats, including feces of many animals and from human clinical sources. S. gallolyticus is part of the rumen flora but also a cause of disease in ruminants as well as in birds (septicemia in pigeons, outbreaks in broiler flocks, or bovine mastitis). This is a tannin-degrading Streptococcus species. Strains have been isolated from various habitats, including feces of many animals and from human clinical sources. This organism can be a cause of infectious endocarditis.
