Test ID: VIBC Vibrio Culture, Feces

Reporting Name

Vibrio Culture, Stool

Useful 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

Clinical Information

Diarrhea may be caused by a number of agents (eg, bacteria, viruses, parasites, and chemicals), and infection with or exposure to one of these agents may result in similar symptoms. A thorough patient history covering symptoms, severity and duration of illness, age, travel history, food consumption, history of recent antibiotic use, and illnesses in the family or other contacts will help the physician determine the appropriate testing to be performed.

 

Vibrio cholerae, the causative agent of endemic, epidemic, and pandemic cholera, results in large volumes of rice-water stools due to the production of an enterotoxin. Severe dehydration is of concern in patients without access to adequate medical care. In the United States, Vibrio parahemolyticus is the most common cause of Vibrio disease. V parahemolyticus is associated with the consumption of raw shellfish or fish and results in gastroenteritis with nausea, vomiting, abdominal cramps, low-grade fever, and chills. Usually rehydration is the only treatment required, although in some cases, antimicrobial therapy is needed.

Interpretation

The growth of Vibrio species identifies a potential cause of diarrhea.

Conventional Culture

Specimen Type

Fecal


Additional Testing Requirements


1. If susceptibility testing is desired, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, MIC, 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.
