Evaluation of CHROMagar STEC and STEC O104 chromogenic agar media for detection of Shiga Toxin-producing Escherichia coli in stool specimens.
The performance of CHROMagar STEC and CHROMagar STEC O104 (CHROMagar Microbiology, Paris, France) media for the detection of Shiga toxin-producing Escherichia coli (STEC) was assessed with 329 stool specimens collected over 14 months from patients with suspected STEC infections (June 2011 to August 2012). The CHROMagar STEC medium, after an enrichment broth step, allowed the recovery of the STE...
متن کاملDetection of Shiga toxin-producing Escherichia coli (STEC) in faeces of healthy calves in Mashhad, Iran
The aim of this study was to identify virulent Shiga toxin-producing Escherichia coli (STEC) strains isolated from faecal samples of 100 clinically healthy calves. In the present study, a total of 100 Escherichia coli (E. coli) isolates from clinically healthy calves belonging to 6 different farms located in Khorasan Razavi province, Iran, were examined for presence of virulence genes character...
متن کاملDetection of verotoxin (Shiga-like toxin)-producing and eae harboring Escherichia coli in some wild captive and domestic Equidae and Canidae
The aim of this study was to investigate the prevalence of STEC and EPEC strains and E. coli O157 serogroup in some Equidae and Canidae. The fecal samples of 79 animals from 6 different species were evaluated for presence of these strains. All the Isolates were tested for virulence genes using multiplex-PCR. Non-sorbitol fermenting (NSF) Escherichia coli isolates and positive strains for virule...
متن کاملIsolation, Characterization and Antibiotic Resistance of Shiga Toxin-Producing Escherichia coli in Hamburger and Evolution of Virulence Genes stx1, stx2, eaeA and hly by Multiplex PCR
Background & Objectives: Shiga toxin-producing Escherichia coli (STEC) O157:H7 have emerged as pathogens that can cause food-borne infections and severe and potentially fatal illnesses in humans. E.coli O157:H7 colonizes the digestive tract of cattle and is transmitted to humans by food and water. The objectives of this study were to characterize the prevalence of E.coli O157:H7 isolates in ham...
متن کاملDetection and Molecular Characterization of Sorbitol Negative Shiga Toxigenic Escherichia Coli in Chicken from Northwest of Iran
Shiga toxin-producing Escherichia coli (STEC) are food-borne pathogens primarily associated with the consumption of contaminated ground beef and are an important food safety concern worldwide. STEC has been found to produce a family of related cytotoxins known as Shiga toxins (Stxs). Shiga toxins have been classified into two major classes, Stx1 and Stx2. A single strains of STEC can produce St...
