Uncinaria stenocephala is one of the commonest nematode parasites targeting dogs, cats, and foxes as well as humans. Common name: The Northern hookworm of dogs.

Life Cycle

The host ingests an infective third stage-larva. The larva matures to the adult in the small intestine. Eggs are laid in the small intestine and pass out with the feces. The pre-patent period is about 15 to 17 days. The eggs hatch in the soil and the larvae molt twice to reach the infective third-stage.

Adult parasite is most often found in hosts small intestine.
