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.
Useful For: Determining whether Vibrio species is the cause of diarrhea and, in turn, identifying the
source of the infectious agent
Interpretation: The growth of Vibrio species identifies the cause of diarrhea.
Reference Values:
No growth

Viral Culture, Non-Respiratory
Clinical Information: Viruses are responsible for a broad spectrum of clinical symptoms and
diseases. The most commonly isolated viruses are: adenovirus, cytomegalovirus, enteroviruses, herpes
simplex virus, and varicella-zoster virus. Many viral infections can now be treated with antiviral drugs.
Early laboratory diagnosis by isolation is very helpful in the medical management of these patients.
Useful For: Diagnosing viral infections
Interpretation: A positive result indicates that virus was present in the specimen submitted. Clinical
correlation is necessary to determine the significance of this finding. Negative results may be seen in a
number of situations including absence of viral disease, inability of the virus to grow in culture (examples
of organisms not detected by this culture test include Epstein-Barr virus, rubella virus, papilloma, and
Norwalk virus), and nonviable organisms submitted. For patients with diarrhea, see Parasitic Investigation
of Stool Specimens Algorithm in Special Instructions for other diagnostic tests that may be useful.
Reference Values:
Negative
If positive, virus is identified.

Viral Culture, Respiratory
Clinical Information: Viruses are responsible for a broad spectrum of clinical symptoms and
diseases. The most commonly isolated viruses are adenovirus, cytomegalovirus, enteroviruses, herpes
simplex virus, influenza virus, parainfluenza virus (types 1-3), respiratory syncytial virus, and
varicella-zoster virus. Many viral infections can now be treated with antiviral drugs. Early laboratory
