Query: NC_015730:3853065 Roseobacter litoralis Och 149 chromosome, complete genome
Lineage: Roseobacter litoralis; Roseobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This type strain for the species was collected from seaweed and isolated by direct plating. Capable of performing aerobic anoxygenic photosynthesis. Photosynthesis genes are located on a plasmid, which is unusual for aerobic anoxygenic phototrophs.
Subject: NC_009879:260000 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.
