Query: NC_016931:269537 Rickettsia massiliae str. AZT80 chromosome, complete genome

Lineage: Rickettsia massiliae; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria

General Information: Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism 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. This bacterium is a member of the spotted fever group of the Rickettsiales and has been isolated from ticks in Europe and Africa. Rickettsia massiliae does not appear to cause disease in humans.

Subject: NC_003047:74986 Sinorhizobium meliloti 1021, complete genome

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

General Information: Streptomycin resistant derivative of strain 2011. Plant symbiotic bacterium. This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, in this case the alfalfa plant (Medicago sativa). 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.
