Query: NC_014551:157418 Bacillus amyloliquefaciens DSM 7, complete genome
Lineage: Bacillus amyloliquefaciens; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Originally isolated from infested soil in Germany. Bacillus amyloliquefaciens is a member of a group of free-living soil bacteria known to promote plant growth and suppress plant pathogens. Bacillus amyloliquefaciens is able to degrade myo-inositol hexakisphosphate (phytate), making phosphorus more available to plants. This organism also produces antifungal and antibacterial substances, such as bacillomycin D, surfactin, and bacillaene, which protect the plant from pathogenic organisms. In addition, proteases and amylases produced by Bacillus amyloliquefaciens are used in industrial applications.
Subject: NC_006142:683000 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.
