The Non-O157 Shiga-Toxigenic (Verocytotoxigenic) Escherichia coli; Under-Rated Pathogens From: Critical Reviews in Microbiology | Date: January 1, 2007| Author: Bettelheim, Karl A | Copyright Taylor & Francis Ltd. 2007. Provided by ProQuest LLC.Copyright information

Following a brief review of the ecology of Escherichia coli in general, the role of Shiga-Toxigenic (Verocytotoxigenic) E. coli (STEC) as pathogens is addressed. While STEC belonging to the serogroup O157 have been extensively studied and shown to be involved in many cases and outbreaks of human disease, the importance of STEC belonging to other serogroups has not been recognized as much. This review addresses the problems associated with these pathogens, demonstrating that increasing the awa...
