Cholera

How is the infection diagnosed?

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.
