Query: NC_016931:38350 Rickettsia massiliae str. AZT80 chromosome, complete genome Lineage: Rickettsia massiliae; 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. This bacterium is a member of the spotted fever group of the Rickettsiales and has been isolated from ticks in Europe and Africa. Rickettsia massiliae does not appear to cause disease in humans.

General Information: This organism was one of the first bacteria studied, and was named Vibrio subtilis in 1835 and renamed Bacillus subtilis in 1872. It is one of the most well characterized bacterial organisms, and is a model system for cell differentiation and development. This soil bacterium can divide asymmetrically, producing an endospore that is resistant to environmental factors such as heat, acid, and salt, and which can persist in the environment for long periods of time. The endospore is formed at times of nutritional stress, allowing the organism to persist in the environment until conditions become favorable. Prior to the decision to produce the spore the bacterium might become motile, through the production of flagella, and also take up DNA from the environment through the competence system. The sporulation process is complex and involves the coordinated regulation of hundreds of genes in the genome. This initial step results in the coordinated asymmetric cellular division and endospore formation through multiple stages that produces a single spore from the mother cell.
