What are sentinel animals used for in research facilities?

Sentinel animals are specifically used in research facilities to monitor the health status of the animal population and to detect diseases that may not be immediately evident in the other animals housed in the facility. The purpose of using sentinel animals involves placing them in various environments within the facility to assess exposure to pathogens and other health concerns. These animals are regularly tested for specific diseases, and any signs of illness can indicate a potential outbreak affecting the larger population.

This practice is crucial in maintaining the overall health and well-being of all the animals within the facility and ensuring that research results are not compromised by underlying diseases. Sentinel animals thus play a vital role in animal health monitoring programs, which contribute to the integrity of animal research and the welfare of the animals involved.
