Study Notes
Hookworms Overview
- Common internal parasites affecting primarily puppies; less common in cats.
- Hookworms belong to the genera Ancylostoma (Southern) and Uncinaria (Northern).
- Characterized by their ability to suck blood from the host, leading to anemia and weakness.
Life Cycle
- Adult hookworms live in the small intestine, attaching via sharp teeth.
- Female worms produce eggs, which are shed in the host's feces.
- Larvae develop through three stages: hatchling, second stage, and third stage ready for infection.
- Infection routes include skin penetration (especially through feet) and ingestion from contaminated soil.
- Larvae may migrate through the body, potentially developing in lung tissue before returning to the intestine to mature.
Transmission
- Can be transmitted from mother to unborn puppies through placental or mammary routes.
- Cutaneous larva migrans indicate zoonotic potential, meaning they can infect humans.
Clinical Signs
- Symptoms in puppies include anemia, weakness, paleness, and potential diarrhea.
- A cough may occur due to larval migration to the lungs.
Diagnosis and Treatment
- Diagnosis is typically done via fecal float methods to detect eggs.
- Treatment primarily involves deworming agents such as Mebendazole, Fenbendazole, and Pyrantel pamoate.
- Deworming may need to be repeated to target migrating larvae; supportive treatments like blood transfusions and iron supplements are often necessary for severely affected puppies.
Prevention
- Regular deworming protocols and cleanliness can help prevent hookworm infections.
