Query: NC_014976:1174430 Bacillus subtilis BSn5 chromosome, complete genome

Lineage: Bacillus subtilis; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria

General Information: Bacillus subtilis BSn5 was isolated from Amorphophallus konjac calli tissue culture. Bacilllus subtilis BSn5 could inhibit Erwinia carotovora subsp. carotovora strain SCG1, which causes Amorphophallus soft rot disease and affects Amorphophallus industry development 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.

Subject: NC_006142:33268 Rickettsia typhi str. Wilmington, complete genome

Lineage: Rickettsia typhi; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria

General Information: 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. Rickettsia typhi causes murine typhus and is an obligate intracellular pathogen that infects both the flea vector and hosts such as human, rat, and mouse. In the flea vector, the bacterium penetrates the gut epithelial barrier and is found in the feces which become infective.
