The diagnosis of cholera begins with a complete medical
history and physical examination. Sometimes, the doctor can see
the bacteria in a stool sample by using a microscope. In other cases, a
stool culture is needed. Stool culture involves putting a sample
of stool in a special container. This container has a solution in
it that allows the Vibrio cholerae bacteria to
grow. If the organism grows, it can be identified, and the
diagnosis can be made.
