Query: NC_006351:3159630 Burkholderia pseudomallei K96243 chromosome 2, complete sequence
Lineage: Burkholderia pseudomallei; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This strain was a clinical isolate from Thailand. The genome of this organism carries many genomic islands as compared to the related organism B. mallei, suggesting extensive horizontal transfer. Opportunistic pathogen. This species is an opportunistic pathogen and can cause pneumonia, bacteremia, and melioidosis. It is normally found in terrestrial environments and has been recovered from rice paddies and moist tropical soil. It is endemic in Asia and Australia, but can be found in other parts of the world. The organism can exist intracellularly and can spread through the bloodstream (bacteremia).
Subject: NC_004547:164000 Erwinia carotovora subsp. atroseptica SCRI1043, complete genome
Lineage: Pectobacterium atrosepticum; Pectobacterium; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain (ATCC BAA-672) is a virulent blackleg isolated from the stem of a potato plant. Causative agent for blackleg and soft rot disease in potatoes. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Both Pectobacterium chrysanthemia and Pectobacterium carotovora cause soft-rot diseases of various plant hosts through degradation of the plant cell walls. 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. Pectobacterium atrosepticum is an environmentally widespread organism that causes blackleg and soft rot disease in potatoes. This organism produces pectolytic enzymes that destroy plant tissue and allow the bacteria to spread.
