Query: NC_008800:2806827 Yersinia enterocolitica subsp. enterocolitica 8081 chromosome,
Lineage: Yersinia enterocolitica; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This isolate (strain 8081; NCTC 13174) is a mouse-lethal serotype of Yersinia enterocolitica that contains a high pathogenicity island (HPI) that encodes an iron uptake system (yersiniabactin) and a type II secretion system. Causes gastroenteritis. Specific virulence factors are encoded within pathogenicity islands (PAIs) that are required for the invasive phenotype associated with Yersinia infections. One key virulence plasmid contained by the three human-specific pathogens is pCD1/pYv, which encodes a type III secretion system for the delivery of virulence proteins that contribute to internalization into the host cell. This species is a food and waterborn pathogen that causes gastroenteritis (inflammation of the mucous membranes of the stomach and intestine) and is able to proliferate at temperatures as low as 4 degrees C.
Subject: NC_009649:16907 Klebsiella pneumoniae subsp. pneumoniae MGH 78578 plasmid pKPN3,
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.
