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_014219:2931796 Bacillus selenitireducens MLS10 chromosome, complete genome
Lineage: Bacillus selenitireducens; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Isolation: Anoxic muds of Mono Lake California; Country: USA; Temp: Mesophile; Habitat: Fresh water. Bacillus selenitireducens MLS-10 was isolated from alkaline, hypersaline, arsenic-rich mud from Mono Lake, California. This organism can reduce arsenate, selenate, and selenite, making it a potential bioremediation agent. Bacillus selenitireducens produces intracellular and extracellular granules of elemental selenium when grown on selenite. The respiratory arsenate reductase has been purified, and is able to function at high pH and alkalinity.
