Answer 1

The causative agent of cholera is Vibrio cholerae, a Gram-positive bacteria, spiral in shape.

Explanation:

The preceding assertion about Cholera is incorrect. Cholera is primarily a water-borne disease caused by Vibrio cholera, a Gram-negative motile rod bacterium initially discovered by Robert Koch in 1883. It causes watery diarrhoea with characteristic rice-water stools, leading to dehydration and death in severe instances. To kill the bacteria, antibiotics such as tetracycline might be administered. To maintain the water-electrolyte balance, the patient was administered Oral Rehydration Solution (ORS).
