Giant rats trained to detect tuberculosis in prisons

Rats are already used to sniff out landmines, but now they are going to be used to sniff out tuberculosis (TB) in Tanzania and Mozambique.

Scientists from APOPO, a non-governmental organisation, have trained African giant pouched rats to detect the disease.

The organisation will use them in crowded prisons, where TB often goes undiagnosed, because prisoners do not have money or awareness to go to screenings.
