Query: NC_017048:452000 Rickettsia prowazekii str. GvV257 chromosome, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This species is the causal agent of typhus. The bacteria are transmitted via an insect, usually a tick, to a host organism, in this case humans, where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Transovarial transmission (from mother to offspring) occurs in the invertebrate host.
Subject: NC_007794:2839239 Novosphingobium aromaticivorans DSM 12444, complete genome
Lineage: Novosphingobium aromaticivorans; Novosphingobium; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: This strain, also known as F199, was isolated from a sample obtained at a depth of 410 m from a borehole sample that was drilled at the Savannah River Site in South Carolina, USA. Aromatic hydrocarbon-degrading bacterium. This organism is unusual in that it has glycosphingolipid in the cell envelope instead of the lipopolysaccharide found in most other gram negative organisms. It is typically isolated from a wide range of environmental sites.
