Query: NC_017056:804416 Rickettsia prowazekii str. BuV67-CWPP chromosome, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This species is the causal agent of typhus. 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.
Subject: NC_003869:2143892 Thermoanaerobacter tengcongensis MB4, complete genome
Lineage: Caldanaerobacter subterraneus; Caldanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: This organism was originally isolated from a hot spring in Tengcong, China, and is the type strain for the species. Genomic analysis indicates it is similar to Bacillus halodurans and that it has one of the most biased leading strand distribution of genes. Although the organism has not been observed to be motile or to sporulate, it does contain genes for both functions. The bacterium produces acetate and ethanol from glucose and cannot degrade xylan and cellulose.
