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_006831:250074 Ehrlichia ruminantium str. Gardel, complete genome
Lineage: Ehrlichia ruminantium; Ehrlichia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain was isolated from the Caribbean island of Guadeloupe. Obligate intracellular bacterium and causative agent of heartwater. This organism causes heartwater, a disease with a high mortality rate that affects both wild and domesticated ruminants in sub-Saharan Africa and parts of the Caribbean. The name heartwater refers to the hydropericardium (excessive fluid in the sac surrounding the heart) commonly found associated with infection. This organism is found in membrane-bound vacuoles in endothelial cells and neutrophils and is an obligate intracellular parasite.
