Query: NC_016931:171444 Rickettsia massiliae str. AZT80 chromosome, complete genome
Lineage: Rickettsia massiliae; 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 bacterium is a member of the spotted fever group of the Rickettsiales and has been isolated from ticks in Europe and Africa. Rickettsia massiliae does not appear to cause disease in humans.
Subject: NC_004603:3080614 Vibrio parahaemolyticus RIMD 2210633 chromosome I, complete
Lineage: Vibrio parahaemolyticus; Vibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: This is a clinical strain isolated in 1996 in Osaka, Japan. It contains a type III secretion system which may enable colonization and penetration of the host intestinal epithelial layer, and possibly lead to septicemia. The genome contains multipe chromosomal rearrangements as compared to Vibrio cholerae. The organism also produces a hemolysin (thermostable direct hemolysin - TDH) that is particular to Vibrio parahaemolyticus. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. This species causes food poisoning (gastroenteritis) in countries that have elevated levels of seafood consumption such as Japan.
