Scientists at Durham University have found that dogs can help diagnose malaria, reports The Guardian. People infected with parasitic organisms do not always have the traditional symptoms of malaria, but they all have a peculiar smell..

The experiment involved children from the Gambia: 30 schoolchildren suffering from malaria, who did not show obvious symptoms of the disease, and 143 healthy.

Children were given nylon socks that they put on at night. In the morning, socks in special freezers were transported to the UK, where two dogs - a Labrador and a Labrador Retriever - for several months learned to identify malaria by the smell of the socks of a potential sick person.

As a result, dogs with 70 percent accuracy determined which socks belong to sick children, with 90 percent accuracy which belong to healthy. Scientists believe that dogs experienced difficulties when the plasmodium causing the disease was not in the asexual stage of development.. Also, the results could be affected by cases when sick and healthy children were sleeping in the same bed..

Earlier, American scientists concluded that dogs can distinguish words from pseudowords..
