Shiga toxin-producing E. coli (STEC): What you Need to Know Now

When a patient presents with acute bloody diarrhea and tests negative for common causes such as campylobacter and salmonella, what's missing? Shiga toxin-producing E. coli (STEC) is increasing in prevalence and responsible for a growing number of outbreaks. Per CDC guidelines, rapid accurate diagnosis is critical to reduce the risk of developing life-threatening complications. We will explore newly published studies that emphasize the variability in sensitivity of available testing methods, and examine the impacts to workflow and clinical utility of broth-based testing and direct stool assays. How the CDC recommendations affect assay choices and impact epidemiology will also be discussed.
