PHO Grand Rounds: Non-O157 Shiga toxin-producing E. coli: An emerging pathogen of public health importance
Tuesday, June 17, 2014 12:00 pm to 01:00 pm
Venue: 480 University Ave, Suite 300 Toronto, ON M5G 1V2 Boardroom 350
Laboratory Testing and Sciences
City: Toronto
Format: In Person; Webinar

Note: This is an open invitation, and may be forwarded to interested parties.

Unlike E. coli O157, non-O157 Shiga toxin-producing E. coli (STEC) is not routinely tested in front-line laboratories. Despite this, there have been several prominent international outbreaks of non-O157 STEC with high morbidity and high mortality, such as the German outbreak of E. coli O104 in 2011. This presentation will review the epidemiological and clinical spectrum of disease caused by non-O157 STEC and current efforts in Ontario for clinical diagnostic and response capacity.

Presenter: Dr. Vanessa G. Allen

Dr. Vanessa G. Allen is chief, Medical Microbiology, Public Health Ontario Laboratories, and a medical microbiologist and infectious disease specialist with clinical expertise and research interests in enteric and food- and water-borne microbiology and sexually transmitted infections. Her particular focus is on the use of molecular and other laboratory tools to enhance clinical diagnostic capacity and to understand the transmission and evolution of microorganisms of public health priority to guide public health action. She is co-chair of the Canadian Public Health Laboratory Network’s Water Food Safety and Enterics working group and the Clinical Laboratory Standards Institute’s multidrug-resistant gonorrhea working group.
