Term Description

Qualitative detection of nucleic acid sequences in Escherichia coli DNA in positive blood culture specimens by target amplification and non-probe detection methods, such as melt curve analysis. This term was created for, but not limited in use to, the submitter's test kit, FilmArray Blood Culture Identification panel v2. This assay does not differentiate between E coli, the primary pathogen of interest, and various Shigella species, which are both phenotypically and genetically similar to E coli but rarely isolated from blood culture.

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
