Because the malaria parasites cause people who are infected to have a distinctive odor, dogs have been trained to detect malaria from socks worn by the people infected. This study was conducted by the London School of Hygiene & Tropical Medicine (LSHTM), the Medical Research Council Unit the Gambia at the London School of Hygiene & Tropical Medicine, and experts from a charity, Medical Detection Dogs.
While the use of dogs to detect malaria is not widespread, experts hope to be able to train more dogs and use them at ports of entry to detect people who are infected with malaria. It will also give health care professionals a fast and easy way to determine who has malaria in remote villages.
However, more tests need to be conducted to see if the dogs can detect different stages of malaria and also to see if the scent varies with malaria species in different parts of the world. I have no doubt that dogs will become the most useful tool to detect the early stages of malaria.
Dogs are increasingly being trained to detect unusual things. The latest job is detecting the very difficult to find, Hermit beetle and its larva which live for up to three years hidden in places such as hollow trees in wooded areas.
The use of dogs was the brainchild of Dr. Fabio Mosconi of the Italian Agricultural Research Council and Spienza University of Rome. They have successfully trained Teseo, a Golden Retriever, to detect the endangered beetle.
Beetle detection is another job to add to the growing list of things dogs have and are being used to detect. Besides finding the commonly known things, such as drugs, bombs, humans, and agricultural items at airports, dogs have been used to find such items as Wolf scat, Bird nests, toxic mold, old money, lost pets, and gold ore just to name a few. Dogs are also able to alert people to oncoming seizures, low blood sugar and cancer.
Although scientists are still trying to develop a machine that can equal the scenting capabilities of dogs, they have yet to succeed. Dogs are truly man’s best friend performing so many jobs other than detection work.
