Query: NC_009655:866281 Actinobacillus succinogenes 130Z chromosome, complete genome
Lineage: Actinobacillus succinogenes; Actinobacillus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: Succinate-producing bacterium. Originally isolated from bovine rumen, this species is one of the most promising succinate producers known. It can utilize a variety of sugars and produce a very high volume of succinate, which is used by the pharmaceutical industry. This organism has been improved over time by growth on fermentable carbon and sodium monofluoroacetate and selection of fluoroacetate-resistant mutants which have a higher succinate yield. The succinate yield has also been improved via a metabolic engineering approach, by cloning and overproducing the PEP-carboxykinase gene which catalyzes the addition of carbon dioxide to PEP to form oxalacetate and can work physiologically in both directions
Subject: NC_009648:2699739 Klebsiella pneumoniae subsp. pneumoniae MGH 78578, complete genome
Lineage: Klebsiella pneumoniae; Klebsiella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain was isolated from a patient in 1994. Opportunistic pathogen that causes multiple hospital-acquired infections. This organism is the most medically important organism within the genus Klebsiella. It is an environmental organism found in water, soil, and on the surface of plants. Several strains have been isolated from plant tissues and are nitrogen-fixing endophytes that may be a source of nitrogen for the plant. Other strains can become opportunistic pathogens which infect humans, and typically causes hospital-acquired infections in immunocompromised patients. Major sites of infection include the lungs, where it causes a type of pneumonia, and urinary tract infections. Klebsiella can also enter the bloodstream (bacterimia) and cause sepsis. The pathogen can also infect animals and cause inflammation of the uterus in horses as well as more generalized infections in other mammals. This organism expresses numerous pathogenicity factors, including multiple adhesins, capsular polysaccharide, siderophores, and lipopolysaccharide for the evasion of host defenses. The multiple antibiotic resistance genes carried on the chromosome inhibit efforts to clear the organism from infected patients via antibiotic use.
