Query: NC_013508:3593000 Edwardsiella tarda EIB202, complete genome
Lineage: Edwardsiella tarda; Edwardsiella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Edwardsiella tarda is a Gram-negative member of the normal gut microflora of fish, humans, chickens and other animals. This organism is also a serious pathogen of marine and freshwater fish and has been isolated from channel catfish, Japanese eels, flounder, tilapia, and other economically important fish. Infection by this organism is characterized by septicemia, internal abscesses, and skin lesions. This disease is often associated with poor water quality and mortality in aquaculture can be high. Edwardsiella tarda also causes opportunistic infections in humans, most commonly gastroenteritis and wound infections. However, this organism has been isolated from cases of septicemia and meningitis, primarily in immunocompromised patients.
Subject: NC_007951:2233676 Burkholderia xenovorans LB400 chromosome 1, complete sequence
Lineage: Burkholderia xenovorans; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Originally identified as Pseudomonas sp. LB400 that was found in contaminated soil in upstate New York, USA, this organism is now classified in the genus Burkholderia. Polychlorinated biphenyl-degrading bacterium. Member of the genus Burkholderia are versatile organisms that occupy a surprisingly wide range of ecological niches. These bacteria are exploited for biocontrol, bioremediation, and plant growth promotion purposes. Burkholderia xenovorans has been found on fungi, animals, and from human clinical isolates such as from cystic fibrosis (CF) patients. It may be tightly associated with white-rot fungus, as the degadation of lignin by the fungus results in aromatic compounds the bacterium can then degrade. This organism is exceptionally capable of degradation of polychlorinated biphenyls (PCBs), which are environmental pollutants, and thus it may play a role in bioremediation of polluted and toxic sites and is studied as a model bioremediator. PCBs can be utilized as the sole carbon and energy source by this organism. The pathways for degradation of PCBs have been extensively characterized at both the genetic and the molecular level and have become a model system for the bacterial breakdown of these very persistent environmental contaminants.
