Query: NC_017056:804416 Rickettsia prowazekii str. BuV67-CWPP 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_002678:7004370 Mesorhizobium loti MAFF303099, complete genome
Lineage: Mesorhizobium loti; Mesorhizobium; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Plant symbiont bacterium. This organism contains a symbiosis island that is responsible for symbiotic relationships with plants (lotus) which is similar to what is observed with other Rhizobia that form similar relationships with legumes. The bacterium enters root nodules and performs nitrogen-fixation for the plant cell while being provided with a protective environment to grow in. Nitrogen fixation and root nodule formation genes are carried on a symbiosis island.
