Hanging Drop for V.cholerae

Vibrio cholerae is the bacterium that causes cholera, a severe diarrheal illness. The Hanging Drop test for V. cholerae is an essential tool in the diagnosis of cholera, particularly in regions where the disease is prevalent.


  • Profile Name: Hanging Drop for V.cholerae
  • Sample Type: Stool
  • Preparations Required: There are no specific instructions for preparing for this test. Maintain your usual food and fluid intake unless otherwise instructed by your doctor.
  • Report Time: 4 hours

In a Hanging Drop test, a sample of the patient's stool is placed on a special slide that has a depression. The slide is inverted, and the stool sample is suspended from the underside of the cover slip, creating a "hanging drop." This allows for the observation of live bacteria in their natural, motile state.

The unique, rapid, darting motion of V. cholerae bacteria, known as the "shooting star" motility, can be seen under the microscope in a positive test. The diagnosis of cholera can have significant implications, as timely treatment is essential to prevent severe dehydration and potentially fatal complications.
