Query: NC_011978:493800 Thermotoga neapolitana DSM 4359, complete genome
Lineage: Thermotoga neapolitana; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: This hyperthermophilic organism was first isolated from a black smoker in the bay near Naples, Italy in 1986. This organism, like other Thermotoga, produces a vast quantity of hydrogen in batch culture. It is being considered for use in projects to utilize waste carboydrates for the production of hydrogen gas for industrial purposes. A number of thermostable enzymes such as alkaline phosphatase are also produced by this bacterium and may be of use for industrial purposes.
Subject: NC_012633:276500 Rickettsia africae ESF-5, complete genome
Lineage: Rickettsia africae; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was isolated from a cattle tick, Amblyomma variegatum, collected in Ethiopia. This organism, a member of the spotted fever group of the Rickettsiales, is found in sub-Saharan Africa and the Caribbean. Rickettsia africae causes a flu-like illness, characterized by a mild fever and severe headache, without the skin rash common to other spotted fever group Rickettsia species. Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism 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.
