Toxin test: This test is used to detect the Shiga toxin directly using enzyme immunoassay (EIA). Stool cultures detect O157 STEC but do not detect non-O157 STEC. Therefore, the CDC recommends that EIA to detect Shiga toxins be used in conjunction with stool cultures. Detection of non-O157 ...
Introduction Rapid detection of Shiga toxin-producing Escherichia coli (STEC) enables appropriate treatment. Numerous commercially available molecular tests exist, but they vary in clinical performance. This systematic review aims to synthesise available evidence to compare the clinical performance of enzyme ...
摘要: Aims: To evaluate the suitability of the commercially distributed Ridascreen® Verotoxin enzyme immunoassay (EIA) for detection of known genetic types of the Vero (Shiga) toxins 1 (Stx1) and 2 (Stx2) families and to determine its relative sensitivity and specificity.关键词:...
Shiga toxin producingEscherichia coli(STEC),Salmonellaspp., andYersiniaspecies was investigated in humans, animals, and foods in San Luis, Argentina. A total of 453 samples were analyzed by culture and PCR. The antimicrobial susceptibility of all the strains was studied, the genomic relationships am...

Shiga toxin (Stx)-producing Escherichia coli (STEC) bacteria are a frequent cause of food-borne gastroenteritis, hemorrhagic colitis, and hemolytic uremic syndrome. Because antimicrobial agents are generally contraindicated in patients infected with STEC, a sensitive and specific diagnostic test with ...
Shiga toxin (Stx) may be detected using EIA or PCR; however, the organism is not isolated for subsequent characterization.All hospital laboratories in the Chicago area were surveyed to determine procedures for identifying O157 and other STEC strains. Referral laboratories identified by hospitals that ...
