    ..This study demonstrates that swine STEC comprise a heterogeneous group of organisms, and the possession of different combinations of E. coli virulence genes indicate that some swine STEC can potentially cause human illness. ..

    ..The PCR assays developed in this study can be used for the detection and identification of E. coli O62/O68, O131, O140, O142, and O163 strains isolated from different sources. ..

Foodborne Pathog Dis. 2011;8:601-7 pubmed publisher
    ..This work provides a method for detection and isolation in ground beef and potentially other foods of non-O157 STEC of major public health concern. ..

    ..Further, ABI can potentially serve as an additional processing hurdle to guard against pathogens during processing, transportation, distribution, and/or storage...
  8. Smith J, Fratamico P, Gunther N. Shiga toxin-producing Escherichia coli. Adv Appl Microbiol. 2014;86:145-97 pubmed publisher
    ..Since the non-O157 STEC are responsible for a large portion of STEC-related illnesses, more extensive studies on their physiology, genetics, pathogenicity, and evolution are needed in order to develop more effective control strategies. ..
