Purpose
- Get guidance for detecting Shiga toxin-producing E. coli (STEC).
- Learn about testing for other kinds of diarrheagenic E. coli.
- Submit a STEC specimen to ob体育 for further characterization.
Overview
Testing for STEC
Clinical and public health laboratories can use the following resources for detection and characterization of STEC infections:
Testing for other E. coli
Most U.S. clinical laboratories do not use tests that can detect diarrheagenic E. coli other than STEC, although some have nucleic acid amplification tests available that can detect enterotoxigenic E. coli (ETEC) and other pathotypes.
Public health laboratories can perform additional testing for non-STEC pathotypes; however, these labs usually do so only when investigating an outbreak of diarrheal illness of unknown origin.
In this situation, specimens may be submitted via state health departments to ob体育 for testing.
Submitting specimens
ob体育 offers confirmatory identification, serology, serotyping, subtyping, and virulence profiling for STEC.
