caninum infection is known by veterinarians to be potentially fatal for puppies. Dogs can get infected when they come into contact with the larvae while walking or playing in contaminated areas or when they ingest larvae-ridden feces.Ī. Adult hookworms live in the gut, and their eggs are spread through feces. In dogs, the most common species is Ancylostoma caninum. Hookworms are named for their hook-shaped mouthparts, which they use to latch on to a host's intestinal wall and feed on its blood. Parasitic roundworms are ubiquitous in the animal kingdom. The researchers' discoveries also offer a cautionary tale for the management of human parasite infections. But it may have left a dangerous legacy that poses a risk to all dogs. Once a national pastime, greyhound racing is now nearly extinct in the U.S. Their findings implicate the greyhound racing industry in the rise of these superparasites.

Through a series of studies published over the past few years, Kaplan and his colleagues have traced the origin, evolution and spread of drug-resistant hookworms in dogs. Kaplan had no idea just how big the problem was, however, until he started studying it. If drug-resistant parasites were spreading in dogs, too, that would be worrying. The overuse of antiparasitic drugs in sheep and goats and the trade of these animals have led to widespread drug resistance across the globe. But the infections described in the e-mails sounded like cases of drug resistance, which he had studied in livestock parasites. Kaplan specializes in livestock animals, not pets. The parasites were hookworms, a group of roundworm species that target animals and humans. asking for help with resistant parasitic infections in dogs. In 2017 Ray Kaplan, a parasitologist and veterinarian then at the University of Georgia, started receiving e-mails from colleagues around the U.S.
