How does an animal get hookworm?
A dog may become infected when it inadvertently swallows hookworm larvae, often by grooming its feet, or from sniffing feces or contaminated soil. Most larvae that are ingested will move to the intestinal tract to complete their life cycle.
How are hookworms spread?
How is hookworm spread? Hookworm eggs are passed in the feces of an infected person. If an infected person defecates outside (near bushes, in a garden, or field) or if the feces from an infected person are used as fertilizer, eggs are deposited on soil. They can then mature and hatch, releasing larvae (immature worms).
How are hookworms spread to other dogs?
These eggs are defecated into the environment. They are not immediately able to infect another dog, but after a few days, these eggs mature and can infect another dog if they are eaten. Hookworm infection causes disease through the worms eating and sucking blood from the dog's intestine.
How do hookworms attach to host?
Hookworms use their teeth (A. duodenale) or cutting plates (N. americanus) to fasten onto the mucosa and submucosa, where they secrete a battery of pharmacologically active polypeptides that prevent blood from clotting and downregulate the host inflammatory response.
