Escherichia coli DNA was detected using wec A, wec E, and wec F gene primers. The wec A primers were specific for E. coli. The wec E and wec F primers enabled the detection of the most frequent species of the Enterobacteriaceae found in blood and urine specimens as well as in water. The sensitivity of the assay was approximately 1.2 \u00d7 10<jats:sup>2<\/jats:sup>bacteria\/mL of water. Thus, these primers represent an important step in the molecular diagnosis of major Enterobacteriaceae infections. Their role in the routine testing of contamination in drinking water and food may prove to be very useful. The DNA of Enterobacteriaceae species is detected in a first step PCR, followed by specific identification of important pathogens like E. coli O157, Shigella spp., Salmonella spp., and Yersinia spp.Key words: Enterobacteriaceae, wec gene, enterobacterial common antigen, PCR, biological fluids.<\/jats:p>","DOI":"10.1139\/w01-139","type":"journal-article","created":{"date-parts":[[2003,6,9]],"date-time":"2003-06-09T15:33:14Z","timestamp":1055172794000},"page":"113-122","source":"Crossref","is-referenced-by-count":26,"title":["Development of oligonucleotide primers for the specific PCR-based detection of the most frequent<i>Enterobacteriaceae<\/i>species DNA using<i>wec<\/i>gene templates"],"prefix":"10.1139","volume":"48","author":[{"given":"Paul","family":"Bayardelle","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Zafarullah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"155","reference":[{"key":"p_1\/p_1_1","doi-asserted-by":"crossref","first-page":"171","DOI":"10.1006\/mcpr.1993.1026","volume":"7","author":"Aabo S.","year":"1993","journal-title":"Mol.
