Query: NC_017048:452000 Rickettsia prowazekii str. GvV257 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_008314:1465643 Ralstonia eutropha H16 chromosome 2, complete sequence
Lineage: Cupriavidus necator; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This strain (ATCC 17699; H16), formerly Alcaligenes eutrophus was originally isolated from sludge. Cupriavidus necator also known as Ralstonia eutropha is a soil bacterium with diverse metabolic abilities. Strains of this organism are resistant to high levels of copper or are able to degrade chloroaromatic compounds such as halobenzoates and nitrophenols making them useful for bioremediation. Other strains have been studied for their ability to produce polyhydroxybutyrates which have industrial application. Another strain is able to attack other bacteria and fungi when nutrients in the soil are low.
