Query: NC_008344:950241 Nitrosomonas eutropha C91, complete genome
Lineage: Nitrosomonas eutropha; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria
General Information: Nitrosomonas eutropha C91 was isolated from a sewage disposal plant in Chicago. Ammonia-oxidizing bacterium. This species consists of ammonia-oxidizing bacteria that catalyze the oxidation of ammonia to nitrite and contribute to the global cycling of nitrogen (a process called nitrification). This obligate chemolithoautotroph is studied for that reason.
Subject: NC_000963:995500 Rickettsia prowazekii str. Madrid E, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain is an egg-passaged attentuated avirulent strain that has been used as a live vaccine and was originally isolated from a typhus patient in Madrid. 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.
