Query: NC_016639:274157 Rickettsia slovaca 13-B chromosome, complete genome
Lineage: Rickettsia slovaca; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism 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.
Subject: NC_014654:1 Halanaerobium sp. 'sapolanicus' chromosome, complete genome
Lineage: Halanaerobium hydrogeniformans; Halanaerobium; Halanaerobiaceae; Halanaerobiales; Firmicutes; Bacteria
General Information: Environment: Fresh water, Sediment; Temp: Mesophile; Temp: 34 - 42C. Organisms identified in the genus Halanaerobium (also known as Haloanaerobium) were first isolated from the Great Salt Lake in Utah, USA and have since been isolated from diverse saline environments such as oil reserviors, brine-seawater interfaces and hypersaline sediments. These bacteria are extremely salt-tolerant and are able to grow in concentrations of salt as high as 25%.
