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_010981:594197 Wolbachia pipientis, complete genome
Lineage: Wolbachia endosymbiont of Culex quinquefasciatus; Wolbachia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This bacterial endosymbiont was isolated from the preblastoderm embryos of the Pel strain of Culex quinquefasciatus mosquitoes. This group of bacteria are associated with a variety of invertebrate species, some as pathogens, some in a symbiotic or other type of relationship. Typically these organisms are transmitted maternally from mother to daughter transovarially (through the egg) although these bacteria can affect their hosts reproductive capabilities in order to enhance transmission. The net outcome is the increase of hosts carrying the bacteria in the next generation, thereby increasing transmission.
