Characterization of Shiga Toxigenic Escherichia coli Isolated from Foods
Journal of Food Protection, 2007 The aim of this study was to characterize Shiga toxigenic Escherichia coli (STEC) by PCR using strains isolated from ham, beef, and cattle in Colombia. A total of 189 E. coli strains were tested for the presence of the uidA, stx1, and stx2 genes, and identification was confirmed by the automated PCR BAX system for E. coli O157:H7.

Antimicrobial Resistance and Infection Control, 2018 Background Shiga-toxigenic Escherichia coli strains are one of the most important foodborne bacteria with an emergence of antibiotic resistance. Foodborne STEC strains are mainly associated with presence of certain virulence factors and O-seogroups.

Bovine Immune Response to Shiga-Toxigenic Escherichia coli O157:H7 [PDF]
Clinical and Vaccine Immunology, 2006 ABSTRACT Although cattle develop humoral immune responses to Shiga-toxigenic (Stx + ) Escherichia coli O157:H7, infections often result in long-term shedding of these human pathogenic bacteria. The objective of this study was to compare humoral and cellular immune responses to Stx

A scoping review on the prevalence of Shiga‐toxigenic Escherichia coli in wild animal species [PDF]
Zoonoses and Public Health, 2018 AbstractZoonotic pathogens constitute the major source (60.3%) of emerging infectious diseases. Previous studies have investigated the prevalence of Shiga‐toxigenic Escherichia coli (STEC) among wild animal species, but comprehensive data are needed to assess the role that these animals have in the transmission of STEC infections to the human ...

Animals as sources of food-borne pathogens: A review
Animal Nutrition, 2018 Food-producing animals are the major reservoirs for many foodborne pathogens such as Campylobacter species, non-Typhi serotypes of Salmonella enterica, Shiga toxin-producing strains of Escherichia coli, and Listeria monocytogenes.

Attachment of Shiga Toxigenic Escherichia coli to Beef Muscle and Adipose Tissue
Journal of Food Protection, 2006 Shiga toxigenic Escherichia coli (STEC) serotypes are important foodborne pathogens that cause gastrointestinal disease worldwide. An understanding of how STEC strains attach to surfaces may provide insight into the potential persistence of and contamination with STEC in food environments. The initial attachment of a selection of STEC serotypes to beef

Laboratory Practices and Incidence of Non-O157 Shiga Toxin–producing Escherichia coli Infections
Emerging Infectious Diseases, 2012 We surveyed laboratories in Washington State, USA, and found that increased use of Shiga toxin assays correlated with increased reported incidence of non-O157 Shiga toxin–producing Escherichia coli (STEC) infections during 2005–2010.

A New Family of Potent AB5 Cytotoxins Produced by Shiga Toxigenic Escherichia coli [PDF]
The Journal of Experimental Medicine, 2004 The Shiga toxigenic Escherichia coli (STEC) O113:H21 strain 98NK2, which was responsible for an outbreak of hemolytic uremic syndrome, secretes a highly potent and lethal subtilase cytotoxin that is unrelated to any bacterial toxin described to date. It is the prototype of a new family of AB5 toxins, comprising a single 35-kilodalton (kD) A subunit and
