Query: NC_007086:2408837 Xanthomonas campestris pv. campestris str. 8004, complete genome
Lineage: Xanthomonas campestris; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: The original was isolated from an inflected cauliflower in Sussex, United Kingdom, in 1958. Strain 8004 is a spontaneous rifampicin resistant strain. Causes black rot disease in crucifers. These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. This species is a major cause of black rot in crucifers, a disease that results in massive tissue degeneration. It also produces an extracellular polysaccharide known as xanthan, which is harvested commercially as a food stabilizing agent for use in industry.
Subject: NC_006155:2084669 Yersinia pseudotuberculosis IP 32953, complete genome
Lineage: Yersinia pseudotuberculosis; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain is a fully virulent serotype I strain isolated from a human patient. Environmental bacterium that causes gastrointestinal disease. 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 organism was first isolated in 1883 by Malassez and Vignal and is termed pseudotuberculosis since it causes lesions in the lung that are similar to those observed during tuberculosis infection. It is ubiquitous in the environment and is a food and waterborne pathogen that affects animals as well as humans by causing gastroenteritis like Yersinia enterocolitica.
