Tests are performed using slide, tube and latex agglutinations, as well as inoculation of biochemicals to identify enteric bacteria, Vibrio species, Aeromonas Species and Campylobacter species. Examining and culturing from raw stools for routine enteric pathogens and culturing and identification of shiga toxin-producing E. coli.
Identification of Shigella to the species and type level. Identification of Salmonella serotypes by cell wall and flagellar antigen identification and biochemicals if needed. Identification of E. coli O157:H7 and O grouping (cell wall antigen) of the 6 most common non-O157 shiga toxin-producing E. coli strains. Speciation of Campylobacter, Vibrio, Aeromonas and Plesiomonas species.
Kits can be ordered from the MSPHL. Collection kit includes a double wall mailer with a label. Specimen submission forms can be printed from this website.
Patient Instructions for Submitting Enteric Specimens
Patient Instructions for Submitting Enteric
Please transport the cultures in the proper double wall mailer.
Acceptable specimens for Enteric Bacteriology are inoculated culture slants, Raw Stool specimens and Shiga toxin positive enrichment broths. The MSPHL does not accept culture plates. Only pure culture isolates will be accepted. The Enteric Bacteriology Lab does offer certain non-routine testing of such as Vibrio sp, Yersinia sp. Etc. Raw stool specimens will only be accepted from city or county health departments unless there are special circumstances and previous approval has been obtained.
Test Request Form(s)
Identification to the genus, species, and serotype level.
The following will result in a specimen discarded without testing and the submitter notified:
Specimen is not labeled with the patient name or identifier
No growth on any of the media that is used for testing the specimen
Specimen is mixed
Most cultures can be reported the day after they are received; however, some cultures could take as long as three days to report. Raw stool specimens can be reported anywhere from two to four days after being received.
Many additional tests are available through the Centers for Disease Control and Prevention in Atlanta, GA. Authorization must be made through the State Public Health Laboratory prior to submission of specimens. These additional tests include, but are not limited to, sensitivity testing. More information is available on request.
Assistance in Bacterial Outbreak Situations
The Missouri Department of Health and Senior Services and the State Public Health Laboratory are available to assist in bacterial outbreak situations. Additional tests that may not be routinely offered may be made available during special circumstances, relating to public health concerns. This may include gastrointestinal outbreaks/ foodborne outbreaks of more unusual pathogens.
