Part Description

LP19605-2   Escherichia coli
Escherichia coli (EC) is a gram-negative, flagellated, rod-shaped bacterium. [https://vetmed.iastate.edu/vdpam/FSVD/swine/index-diseases/colibacillosis] The human gastrointestinal (GI) tract is colonized by EC within hours of birth. The natural barriers of the GI tract prevent infection by symbiotic EC except when they break down such as in peritonitis. EC occupy the mucous layer of the mammalian colon and is the most numerous anaerobe of the intestinal microflora. Some strains of EC have evolved virulence factors that precipitate serious disease including enteric diarrhea, urinary tract infections, sepsis and meningitis. The intestinal pathogens of EC include six pathotypes defined by the virulence factors they express. These include: enteropathogenic E. coli (EPEC), enterohaemorrhagic E. coli(EHEC), enterotoxigenic E. coli (ETEC), enteroaggregative E. coli (EAEC), enteroinvasive E. coli (EIEC) and diffusely adherent E. coli (DAEC). Uropathogenic EC (UPEC) is the most common EC infection that occurs outside the GI tract. The EC pathotypes that infects extraintestinal locations have been designated ExPEC. The EC pathotypes that infect animals and cause disease include EPEC, EHEC and ETEC.[nature.com/nrmicro/journal/v2/n2/full/nrmicro818.html][vetres.org/articles/vetres/pdf/2006/01/v6008.pdf] Source: Regenstrief LOINC

Change Reason

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.
