Reporting Name
Vibrio Culture, StoolUseful For
Determining whether Vibrio species may be the cause of diarrhea
This test is generally not useful for patients that have been hospitalized for more than 3 days because the yield from these patients' specimens is very low, as is the likelihood of identifying a pathogen that has not been detected previously.
Performing Laboratory
Mayo Clinic Laboratories in RochesterSpecimen Type
FecalAdditional Testing Requirements
1. If susceptibility testing is desired, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, Varies. If susceptibility testing is not needed (eg, due to lack of recovery of Vibrio species from feces), ZMMLS will not be performed and the order will be canceled.
2. In some cases, local public health requirements may impact Mayo Clinic Laboratories (MCL) clients, requiring submission of isolates to public health laboratories. Clients should familiarize themselves with local requirements and are responsible for submitting isolates to appropriate public health laboratories. Clients can obtain isolates of Vibrio species recovered from specimens submitted to MCL by calling 800-533-1710 as soon as possible after reporting to ensure viability of the bacterium.

Method Description
The fecal specimen is inoculated onto selective media, thiosulfate-citrate-bile salts-sucrose agar (TCBS), designed to inhibit growth of normal bowel flora while allowing growth of Vibrio species. After incubation, suspect colonies are identified using 1 or a combination of the following techniques: matrix-associated laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry, conventional biochemical tests, carbon source utilization, and nucleic acid sequencing of the 16S ribosomal RNA (rRNA) gene.(Tarr CL, Glover WAII, Boucher Y, et al: Chapter 43: Vibrio and Related Organisms.
