Query: NC_010465:2282874 Yersinia pseudotuberculosis YPIII, complete genome
Lineage: Yersinia pseudotuberculosis; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Environmental bacterium that causes gastrointestinal disease. 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.
Subject: NC_011083:2847318 Salmonella enterica subsp. enterica serovar Heidelberg str. SL476,
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This is a multidrug resistant strain. Salmonella enterica subsp. enterica serovar Heidelberg is one of the more common serovars causing disease in the USA. This group of Enterobactericiae have pathogenic characteristics and are one of the most common causes of enteric infections (food poisoning) worldwide. They were named after the scientist Dr. Daniel Salmon who isolated the first organism, Salmonella choleraesuis, from the intestine of a pig. The presence of several pathogenicity islands (PAIs) that encode various virulence factors allows Salmonella spp. to colonize and infect host organisms. There are two important PAIs, Salmonella pathogenicity island 1 and 2 (SPI-1 and SPI-2) that encode two different type III secretion systems for the delivery of effector molecules into the host cell that result in internalization of the bacteria which then leads to systemic spread.
