How do I know if I have Vibrio cholerae?
Isolation and identification of Vibrio cholerae serogroup O1 or O139 by culture of a stool specimen remains the gold standard for the laboratory diagnosis of cholera. Cary Blair media is ideal for transport, and the selective thiosulfate–citrate–bile salts agar (TCBS) is ideal for isolation and identification.
Why is my poop covered in white stuff?
A common source of white specks in the stool is undigested food. Sometimes foods that are difficult to digest — like quinoa, nuts, seeds, high-fiber vegetables, and corn — can actually move through the digestive tract without fully digesting. This can cause small white flecks in the stool.

Vibrio cholerae growing on thiosulphate citrate bile salt sucrose (TCBS) agar plates. Isolation and identification of Vibrio cholerae serogroup O1 or O139 by culture of a stool specimen remains the gold standard for the laboratory diagnosis of cholera.
What is the treatment for cholera?
Cholera can be simply and successfully treated by immediate replacement of the fluid and salts lost through diarrhea. Patients can be treated with oral rehydration solution (ORS), a prepackaged mixture of sugar and salts to be mixed with 1 liter of water and drunk in large amounts. This solution is used throughout the world to treat diarrhea.
