National Enteric Disease Surveillance : Shiga toxin-producing Escherichia coli (STEC) annual report, 2008

In this summary, we summarize the number of isolates reported, as well as isolation rates and specimen submission rates. The isolation rate is the number of STEC isolates from humans reported for a given year, divided by the population for that year. The non-O157 STEC specimen submission rate is the number of presumptive non-O157 STEC isolates and Shiga toxin-positive enrichment culture broths submitted to the enteric diseases laboratory branch (EDLB) at CDC for further characterization for a given year, divided by the population for that year. Reporting to LEDS and submission to the National Escherichia coli Reference Laboratory is voluntary, and the number of states submitting isolates varies from year to year.Reference citation: Centers for Disease Control and Prevention (CDC).
