Molecular Diagnosis of Gastroenteritis/Acute Diarrhea


The presentation will reintroduce the audience to the gastrointestinal pathogens and their respective prevalence in the United States. Classical methodologies will be reviewed and newer molecular methodologies will also be presented. A particular focus on pathogen/host specific epidemiology will be described, and the proposed strategies for incorporating molecular diagnostics in patient care will be discussed. Future impact to public health and patient care concerns will also be explored.

Originally presented on October 14, 2014 in Salt Lake City, Utah.

Dr. Couturier is the medical director of Microbial Immunology, Parasitology and Fecal Testing, and Infectious Disease Rapid Testing at ARUP. He is also an assistant professor of pathology at the University Of Utah School Of Medicine. Dr. Couturier received his PhD in medical microbiology and immunology with specialty in bacteriology from the University of Alberta in Edmonton, Alberta, Canada. He served as a research associate/post-doctoral fellow at the Alberta Provincial Laboratory for Public Health and completed a medical microbiology fellowship (ABMM) at the University of Utah. His research interests include Helicobacter pylori diagnostics and population prevalence, in particular identifying populations with increased risk of infection and reduced access to medical care. Dr. Couturier also has a research focus aimed at developing improved diagnostics for emerging agents of infectious gastroenteritis. He is board certified in medical microbiology, and a member of the American Society for Microbiology and Infectious Disease Society of America.


After this presentation, participants will be able to:

  • Discuss the epidemiology of acute diarrheal illness & approach to testing.
  • Explore the new molecular panel-based methods and their potential role.
  • Consider the incorporation of new diagnostic methods in clinical practice.
