Detection 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...

Characterization of Shiga toxin-producing Escherichia coli (STEC) in feces of healthy and diarrheic calves in Urmia region, Iran

BACKGROUND AND OBJECTIVES Shiga toxin-producing Escherichia coli (STEC) have emerged as human pathogens and contamination of foods of animal origin has been a major public health concern. The aim of the present study was to determine the dissemination of STEC in healthy and diarrheic calves in Urmia region which is located in West Azerbaijan province, Iran. MATERIALS AND METHODS In the curren...

Shiga toxin-producing Escherichia coli (STEC).

Shiga toxin-producing Escherichia coli (STEC) are important enteric pathogens worldwide, causing diarrhea with or without blood visibly present and hemolytic uremic syndrome. STEC are unique among diarrheogenic E coli in producing Shiga toxin type 1 and type 2, the virulence factors responsible for bloody diarrhea and hemolytic uremic syndrome. Cattle and other ruminants are the natural reservo...

Toxin-Producing Escherichia coli Strains STEC Medium in Detection of Shiga Usability and Performance of CHROMagar

Advances in detection methods for Shiga toxin-producing Escherichia coli (STEC)

Shiga toxin-producing Escherichia coli (STEC) comprise E. coli strains capable of producing toxins named Shiga toxin type 1 (Stx1), type 2 (Stx2), or both, encoded by stx1 and stx2 genes, respectively. Stx2 is the most heterogeneous group possessing subtypes that differ in their association with human disease (Friedrich et al., 2002). Other typical virulence factors are intimin (encoded by eae ...
