Prevalence, Molecular Characterization and Serology of Shiga toxin-Producing Escherichia coli Isolated from Buffaloes in West Azerbaijan, Iran
This present study is the first to report the presence of Shiga toxin-producing Escherichia coli (STEC) in buffaloes in Iran. A total of 360 fecal samples were collected from buffaloes from different regions in the west Azerbaijan province of Iran and cultured for the isolation of E. coli using routine biochemical tests. From the fecal samples, 340 E. coli were isolated and, of these, 26 STEC i...
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 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 کاملThe Evolution of Virulence in Non-O157 Shiga Toxin-Producing Escherichia Coli
Shiga toxin-producing Escherichia coli (STEC) are zoonotic foodborne and waterborne pathogens that are a serious public health concern because they cause outbreaks and the potentially fatal hemolytic uremic syndrome (HUS). The most common STEC serotype associated with human disease is O157:H7, but there is a growing recognition of over 100 non-O157 serotypes that also may result in human illnes...
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...
