Query: NC_012917:2921932 Pectobacterium carotovorum subsp. carotovorum PC1, complete genome
Lineage: Pectobacterium carotovorum; Pectobacterium; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Temp: Mesophile; Habitat: Host. Pectobacterium carotovorum causes soft-rot diseases of various plant hosts through degradation of the plant cell walls. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Pectobacterium colonize the intercellular spaces of plant cells and deliver potent effector molecules (Avr - avirulence) through a type III secretion system (Hrp - hypersensitive response and pathogenicity). Avr proteins control host-bacterium interactions, including host range. Expression of the plant cell-wall-degrading enzymes is controlled through a quorum-sensing mechanism that quantifies the number of Pectobacterium bacteria through measurement of the concentration of small molecules (acyl homoserine lactones) produced by Pectobacterium.
Subject: NC_004603:1115134 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.
