Part Description

LP262477-5   Escherichia coli Stx2 toxin stx2 gene
The Stx1 toxin A subunit is encoded by the stx1 gene [www.uniprot.org/uniprot/ ?query=stx1+escherichia+coli&sort=score] and the Stx2 toxin A subunit is encoded by the stx2 gene.[UniProt: K0JD26] Stx1a and Stx2a are produced by some serogroups of Escherichia coli (also known as Vero toxins and previously referred to as Shiga-like toxins) are two cytotoxins that cause hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS). The two toxins produce similar symptoms, but are immunologically unique. Both toxins are composed of a single copy of subunit A and five copies of subunit B. Stx1a and Stx1b induce host cell apoptosis by removing an adenine residue from the 28S rRNA of the 60S ribosome, with RNA-N-glycosidase activity provided by subunit A. The five B subunits bind to the host cell receptor present on endothelial cells. PMID: 25530917 Shigella toxin-producing Escherichia coli (STEC) has become a serious food-borne pathogen. Outbreaks of STEC have been associated with the consumption of pork products resulting in HC and HUS. STEC in swine has been demonstrated to cause edema disease. Epidemiological studies throughout the world have proven that STEC can be harbored and shed by domestic swine. PMID: 24397985 Source: Regenstrief LOINC

Change Reason
Previous Releases: Changed Component from "Bacterial shiga-like toxin 2 (stx2) gene" to "Escherichia coli shiga-like toxin 2 (stx2) gene" since stx1 is only produced by E.coli.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; Updated Component from "Escherichia coli shiga-like toxin 2 (stx2) gene" based on the current E. coli nomenclature and LOINC model.
