I am a comma-shaped bacterial pathogen which spreads through contaminated water and food. I cause severe diarrhoea and water loss in the infected person. If not properly treated the infected person can be dehydrated. Who am I?

Based on the shape, bacterial cells can be coccus (spherical), bacillus (rod-shaped), spirilla (spiral), vibrio (comma-shaped), etc. Vibrio cholerae is a comma-shaped bacteria which causes cholera. The major symptom of cholera is severe diarrhoea with subsequent water loss from the body. If the patients are not treated well and their water loss is not compensated, they can suffer from severe dehydration.
