Query: NC_013941:1963523 Escherichia coli O55:H7 str. CB9615 chromosome, complete genome

Lineage: Escherichia coli; Escherichia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: The E. coli O55:H7 strain CB9615 was isolated from an infant with diarrhea in Germany in 2003 and confirmed to belong to the same sequence type (ST11) as the O157:H7 clone by multilocus sequence typing. The O55:H7 and O157:H7 E. coli clones have been shown to be closely related. This organism was named for its discoverer, Theodore Escherich, and is one of the premier model organisms used in the study of bacterial genetics, physiology, and biochemistry. This enteric organism is typically present in the lower intestine of humans, where it is the dominant facultative anaerobe present, but it is only one minor constituent of the complete intestinal microflora. E. coli, is capable of causing various diseases in its host, especially when they acquire virulence traits. E. coli can cause urinary tract infections, neonatal meningitis, and many different intestinal diseases, usually by attaching to the host cell and introducing toxins that disrupt normal cellular processes.

Subject: NC_006155:2461262 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.
