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_005955:1284500 Bartonella quintana str. Toulouse, complete genome
Lineage: Bartonella quintana; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Bartonella quintana str. Toulouse was isolated from human blood in Toulouse, France in 1993. Causative agent of trench fever. This group of alpha proteobacteria are unique among pathogens in that they cause angiogenic lesions. This organism was first identified as the causative agent of louse-born trench fever during World War I. Up to 800 000 were infected in the trenches because of the louse insect vector that was widespread due to poor sanitation. The disease is now found associated with immunocompromized patients, especially HIV patients and homeless alcoholics.
