Two canine cohorts were applied in a very study on malaria detection.Durham University/Medical Detection Dogs/London Faculty of Cleanline s & Tropical MedicineSeveral years ago, British entomologist Steve Lindsay landed at an American airport and was immediately struck by all the furry creatures walking around the baggage claim area. “I was astounded to see sniffer dogs, looking for fruits and vegetables,” says Lindsay, who studies malaria at Durham University in the U.K. Recent studies have found that people carrying malaria release a signature scent. “So Brad Wing Jersey I thought, ‘Well, if a puppy can smell fruits and vegetables in luggage, could they smell malaria in the person?’ ” Lindsay says. So he set out to create the ultimate disease watchdogs canines that can smell parasites living inside people. Durham University/Medical Detection Dogs/London University of Cleanline s & Tropical MedicineYouTube Then, as people hop off international flights, these watchdogs could take a few sniffs at each person’s skin and paw at the people who might be carrying a parasite. “The person can be taken aside and po sibly tested for the disease with a blood test,” Lindsay explains. Sound far-fetched? Well, it might not be as far from reality as you would think. Goats and Soda Chewa The Lab Rat Has A Great Job, Good Retirement Benefits At a scientific conference on Monday, Lindsay presented preliminary evidence that canine can detect whether a person is carrying the malaria parasite in their blood by just sniffing their odor or more specifically, sniffing a small piece of their sock. The researchers trained the puppies by rewarding them with a snack when they correctly identified and sat next to a malaria-tainted sock. Lindsay and his colleagues trained two canines Sally, a Labrador retriever, and Lexi, a golden retriever-Labrador mix. Although the examine was small, the results had been encouraging. Overall, Sally and Lexi had a succe s rate of about 70 percent for picking out the socks worn by people with malaria; each canine correctly identified at least 21 of the 30 samples. The pet dogs did better with the socks worn by people not infected. Each canine correctly identified at least 131 of the 145 negative samples, for a succe s rate of about 90 percent. Clearly, larger studies are needed, Lindsay says. But the dogs’ performance isn’ t too shabby when you look at how well some commercial tests perform. For example, one study found rapid diagnostic tests correctly detected malaria 60 percent to 90 percent of the time, depending on the particular conditions. And the tests correctly identified the negative samples about 90 percent of the time which is similar to the dogs’ performance. And Sally and Lexi have room to improve, Lindsay says. “We made it hard for the pet dogs,” he says. “We didn’t have many samples to train them with just 30 socks worn by people with malaria. ” Lindsay hopes that trained canine could, one day, work at ports D.J. Fluker Jersey of entry to help countries keep malaria from entering, especially in places that are trying to eliminate the parasite or have just gotten rid of it.”At the moment, malaria detection relies on taking a person’s blood with a pinprick, but you can’t do that to everyone coming acro s a border,” Lindsay says. “The malarial pet dogs would be a noninvasive method of picking up the parasite.” But there’s still quite a bit a work to do before you’ll find Sally and Lexi sniffing your legs at customs areas and baggage claims. For starters, the researchers don’t know whether the canine can actually pick up the scent on a person’s skin in addition to their socks and whether the dogs are able to differentiate between a malaria infection and an infection caused by another pathogen. Finally, Lindsay and his team haven’t tested whether the puppies can detect different species or strains of malaria found in various parts of the world. Still though, if you think about it, the puppies are doing something remarkable, Lindsay says: They’re detecting the presence of a microscopic organism living inside a person’s blood or liver by simply taking a sniff of a sock.
