Query: NC_013943:382807 Denitrovibrio acetiphilus DSM 12809 chromosome, complete genome
Lineage: Denitrovibrio acetiphilus; Denitrovibrio; Deferribacteraceae; Deferribacterales; Deferribacteres; Bacteria
General Information: Isolation: Oil reservoir model column; Country: Norway; Temp: Mesophile; Habitat: Fresh water, Marine. This organism was first isolated from an oil reservoir modeling column under nitrate enrichment and reduces nitrate to ammonia. Stimulating the growth of nitrate-reducing bacterium in an oil well may prevent the growth of sulfate-reducing bacterium which cause reservoir souring by the production of H2S.
Subject: NC_009879:141000 Rickettsia canadensis str. McKiel, complete genome
Lineage: Rickettsia canadensis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was originally isolated from ticks in a field study on tick-transmitted diseases of small mammals in Canada. Member of the typhus group of Rickettsiales. 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. Rickettsia canadensis was originally thought to be a member of the typhus group of Rickettsiales, however, it is now thought to represent a distict group with the rickettsia.
