Query: NC_015690:8019859 Paenibacillus mucilaginosus KNP414 chromosome, complete genome
Lineage: Paenibacillus mucilaginosus; Paenibacillus; Paenibacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Paenibacillus mucilaginosus is critical silicate bacteria in the biogeochemical cycling of potassium, phosphorus, and other soil elements, and is widely used in agriculture, bioleaching, and wastewater treatment. P. mucilaginosus is able to degrade insoluble soil minerals with the release of nutritional ions and fix nitrogen, and thus it has been successfully used as a biofertilizer since the 1990s. The exocellular polysaccharides produced by P. mucilaginosus is also an effective bioflocculant, and thus plays a potential role in the treatment of wastewater and biohydrometallurgy.
Subject: NC_006142:243899 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.
