Query: NC_014219:25845 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.
Subject: NC_003103:266013 Rickettsia conorii str. Malish 7, complete genome
Lineage: Rickettsia conorii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain was isolated from a human in South Africa. Causative agent for Rocky Mountain spotted fever. This genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, is composed of obligate intracellular pathogens. The latter is composed of two organisms, Rickettsia prowazekii and Rickettsia typhi. 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. This organism causes Rocky Mountain spotted fever which can cause severe damage to the endothelial layer of major organs, including the lungs, heart, kidneys, and skeletal muscle which can result in death.
