Rats sniffing out tuberculosis

Scientists at the Eduardo Mondlane University in Maputo, Mozambique are training rats to identify TB-causing bacteria. TB patients have a particular smell that even humans can detect in patients in advanced stages of the disease. Rats, of course, can detect it well before humans. They are a rapid, sensitive and cheap procedure to detect TB in large amounts of samples. They can evaluate 100 samples in less than 20 minutes, while a trained laboratory technician would take approximately four days to process a similar number of samples. The results revealed rats increased TB detection rates in collaborating clinics by more than 40%. In addition, as rats can detect TB more efficiently than microscopy, they could very well be used to screen pregnant women for TB.
