About
Hookworms are small, thin nematodes that are approximately 1 to 2 mm long and live in the duodenum, the first part of the small intestine, where they use six hook-like teeth to attach to the intestinal wall. The hookworm feeds on mucosa and blood and an adult hookworm can consume up to 0.1 ml of blood every day, changing their point of contact every 4-6 hours. Hookworms secrete anticoagulants through their mouth and into the host’s bloodstream at the site of attachment. This prevents the blood from clotting at the feeding site, allowing the hookworm to continuously feed on the host’s blood. A heavy infestation can lead to anemia (low red blood cell count) due to blood loss.
Hookworms are a common intestinal parasitic worm of dogs, cats tend to harbour fewer numbers than dogs.
