80350-2Shigella species+EIEC invasion plasmid antigen H ipaH gene [Presence] in Stool by NAA with non-probe detectionActive

Term Description

This assay detects the invasion plasmid antigen H (ipaH) gene that is specific to Shigella species and enteroinvasive E. coli (EIEC) using PCR and melt curve analysis. The assay does not distinguish between Shigella and EIEC. This term was created for, but is not limited in use to, BioFire's FilmArray Gastrointestinal panel, which is intended for the detection and identification of nucleic acids from multiple bacteria, viruses, and parasites directly from stool samples from individuals with signs and/or symptoms of gastrointestinal infection.

Part Description

LP145956-1   Shigella species+EIEC invasion plasmid antigen H (ipaH) gene
The invasion plasmid antigen H (ipaH) gene is a multicopy gene exclusively found in all Shigella and enteroinvasive E. coli (EIEC). Shigella and EIEC both evolved from nonpathogenic Escherichia coli, and sequencing of multiple housekeeping genes indicates that EIEC is genetically related to Shigella. Shigella causes bacillary dysentery with symptoms including abdominal cramps, nausea, fever and a bloody and mucus diarrhea. By testing for the absence of lysine decarboxylase (LDC) activity and presence of the IpaH gene, Shigella and EIEC can be differentiated from non-enteroinvasive E. coli.

Change Reason
Changed Method from "Melt.amp.tar" to "Non-probe.amp.tar", which includes other non-probe based detection methods while still distinguishing from probe-based methods.; 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.
