Query: NC_011728:376375 Borrelia burgdorferi ZS7, complete genome
Lineage: Borrelia burgdorferi; Borrelia; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This organism is the causative agent of Lyme disease, a multisystemic disease that is considered to be the most prevalent tick-born disease in North America and Europe. This organism was isolated from Ixodes scapularis in 1982. The bacterium is a microaerophilic spirochete that contains seven periplasmic flagella per cell end.
Subject: NC_009900:180970 Rickettsia massiliae MTU5, complete genome
Lineage: Rickettsia massiliae; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Rickettsia massiliae MTU5 was isolated from the tick Rhipicephalus turanicus collected from horses in Le Sambuc, Bouches-du Rhone, France. 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. Rickettsia massiliae 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.
