Query: NC_017057:142000 Rickettsia prowazekii str. RpGvF24 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_012587:1203103 Rhizobium sp. NGR234, complete genome

Lineage: Sinorhizobium fredii; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, such as soybean, cowpea or pigeon pea. Expression of nodulation genes results in production of a nodulation signal which the plant cell recognizes inducing root nodule formation. The plant cell provides carbon compounds for the bacterium to grow on.
