Query: NC_016929:141972 Rickettsia canadensis str. CA410 chromosome, complete genome
Lineage: Rickettsia canadensis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: 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. This organism 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.
Subject: NC_015164:2305415 Bacteroides salanitronis DSM 18170 chromosome, complete genome
Lineage: Bacteroides salanitronis; Bacteroides; Bacteroidaceae; Bacteroidales; Bacteroidetes; Bacteria
General Information: Country: Japan; Environment: Host; Isolation: caecum of chicken; Temp: Mesophile; Temp: 37C. This group of microbes constitute the most abundant members of the intestinal microflora of mammals. Typically they are symbionts, but they can become opportunistic pathogens in the peritoneal (intra-abdominal) cavity. This organism produces many extracellular enzymes which assist in the breakdown of complex plant polysaccharides such as cellulose and hemicellulose and host-derived polysaccharides such as mucopolysaccharides. Bacteroides salanitronis is a species of strictly anaerobic, non-spore-forming, non-motile, Gram-negative rods. It was isolated from caecum of a healthy chicken.
