Query: NC_017048:452000 Rickettsia prowazekii str. GvV257 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_008358:2808299 Hyphomonas neptunium ATCC 15444, complete genome
Lineage: Hyphomonas neptunium; Hyphomonas; Hyphomonadaceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: Marine member of dimorphic prosthecate bacteria. This organism is also known as Hyphomicrobium neptunium. It has a biphasic life style, which consists of a motile phase of flagellated swarmer cells, and a cessile phase in which a long prosthecate is produced at one end of the bacteria through which budding cells emerge. Newly budded cells in turn produce flagella and go through a motile phase and the cycle continues. These organisms can colonize the surfaces of marine environments which enables additional species to colonize at later stages. This organism may be of use in treatment of water as they attach to a solid surface and are capable of degradation of a number of pollutants including aromatic hydrocarbons, dimethyl sulfoxide and methyl chloride.
