Bart Weetjens has always loved rats. As a kid in the Netherlands,he raised them as pets. He was amazed by their intelligence and their great sense of smell. Today,Weetjens is using rats for a good cause identifying (确认) a disease called tuberculosis (肺结核) , or T B. in Africa. Through his organization,called APOPO,Weetjens trains rats to find TB by using their noses. The rats that APOPO trains are called “HeroRats."
Tuberculosis affects millions of people every year. Usually,if a patient is thought to have the disease,doctors run lab tests to identify it. A doctor takes a sample of mucus (枯液样本) from the patient's lungs. Then lab workers examine the sample to see whether the person has the disease.
But Tanzania and Mozambique,two African countries with high rates of T B. are short of medical workers and labs. As a result,it can take a long time to diagnose (诊断) the disease. In the meantime,more people can get sick as the disease spreads.
In 2002,APOPO began training rats to smell TB in mucus samples. It trains African giant rats,which are friendly and hardworking. To detect T B. the rats smell mucus samples through holes in a glass cage. When a trained rat finds a sample with T B. it pauses over the hole.
HeroRats train for months before they start working. To teach a rat to identify T B. a trainer presents the rat with several mucus samples. The trainer already knows which are samples with TB.
If the rat spends a long time smelling a diseased sample,the trainer gives the .rat a treat. This teaches the rat that finding TB will earn it tasty food.
“The rats learn quickly,since they love food/' says Beyene,an APOPO scientist. The rats are faster than lab workers. In 10 minutes,they can screen as many samples as a person could examine in two days. At centers in Tanzania and Mozambique,HeroRats have found thousands of TB cases that labs missed. Thanks to them,sick people can now be treated earlier than ever before. In the future,APOPO hopes to train its rats to identify other diseases too.
