Test Id : VIBC
Vibrio Culture, Feces
Useful For
Suggests clinical disorders or settings where the test may be helpful
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
Highlights
This test provides evidence of the presence of the bacterium, Vibrio species, in feces, in a viable state, and provides an isolate for antibacterial susceptibility testing and, if needed, submission to a health department. Minnesota health care providers are required to report all confirmed or suspected cases of Vibrio bacteriosis to the Minnesota Department of Health. Clients should refer to their local health departments regarding public health submission of Vibrio isolates.

Specimen Type
Describes the specimen type validated for testing
Fecal
Additional 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.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
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.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
No growth of pathogen
Interpretation
Provides information to assist in interpretation of the test results
The growth of Vibrio species identifies a potential cause of diarrhea.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
The yield of Vibrio species is reduced when specimens are delayed in transit to the laboratory (>2 hours from collection for unpreserved specimen).
Buffered glycerol saline is an unacceptable transport media for Vibrio culture.
Check your local public health requirements, which may require submission of isolates to a public health laboratory.

Method Description
Describes how the test is performed and provides a method-specific reference
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 and conventional biochemical tests.(Tarr CL, Glover WAII, Boucher Y, et al: Vibrio and related organisms. In: Carroll KC, Pfaller MA, eds. Manual of Clinical Microbiology. 12th ed. ASM Press; 2019:775-786)
