Using Rats to Sniff Out TB

Apopo’s African giant pouched rats are being used to sniff out mines and TB
No ordinary lab rats, Apopo’s African giant pouched rats – affectionately named HeroRats – are extremely sensitive to smell, with more genetic material allocated to olfaction than any other mammal species. They are also highly social animals, and can be trained to communicate with humans.
I have written about these wonderful rats previously, Appropriate Technology: Rats Helping Humans by Sniffing Out Land Mines. As I have stated many time I especially enjoy engineering solutions that use affordable and effective methods to help everyone.

Keep these innovations coming. The USA needs them also given the massively costly healthcare system in the USA.
The TB sniffing rat program was developed through Apopo in Tanzania.

The success numbers in the original article speaks volumes about what these rats can do in low income countries over the course of time. The cost of medical care really does hinder these countries in a way we don’t seem to think about often here in the United States. By having a rat do the diagnosing at a fraction of the cost of machines, one would think that those funds saved could be used for the treatment of the patient.

I’ve heard of animals being used to sniff out cancer before, but I’ve never heard of them being used to sniff out landmines. Thanks for sharing!
