The transpo medium for stools samples in cholera is –
**Core Concept**
The transport medium for stool samples in cholera is a specialized culture medium that supports the growth of Vibrio cholerae, the causative agent of cholera. This medium is designed to maintain the viability of the bacteria during transportation to the laboratory.
**Why the Correct Answer is Right**
The correct answer is Cary-Blair medium, which is a lactose-free, alkaline peptone water medium that inhibits the growth of other bacteria while allowing Vibrio cholerae to grow. The medium contains ingredients such as peptone, sodium chloride, and sodium bicarbonate, which create an environment that favors the growth of Vibrio cholerae. When a stool sample is inoculated into Cary-Blair medium, the bacteria can survive for several days, allowing for laboratory analysis and isolation.

**Clinical Pearl / High-Yield Fact**
It's essential to note that the transport medium should be kept at a temperature of 4°C to 6°C (39°F to 43°F) during transportation to prevent bacterial growth and inactivation.
**Correct Answer:** C. Cary-Blair medium
