Uncinaria

Uncinaria is a genus of nematodes in the family Ancylostomatidae. The genus includes two species, Uncinaria stenocephala and Uncinaria lucasi, which are parasites of mammals. U. stenocephala is a common parasite of dogs and cats in temperate regions, while U. lucasi infects seals and sea lions in the Arctic and subarctic regions.

Morphology

The worms in the genus Uncinaria are small, with a length of 1-2 cm. They have a cylindrical body, which is whitish in color. The anterior end of the worm is bent dorsally, giving it a hook-like appearance. The mouth is surrounded by two pairs of teeth.

Life cycle

The life cycle of Uncinaria species involves an adult stage in the intestine of the host, where the worms feed on blood and lay eggs. The eggs are passed in the feces of the host. After hatching, the larvae develop in the environment and can infect new hosts by penetrating the skin or by being ingested.

Pathogenicity

Infections with Uncinaria species can cause anemia, weight loss, and diarrhea in the host. In severe cases, the infection can lead to death. The pathogenicity of the worms is related to their blood-feeding behavior and the resulting blood loss in the host.

Treatment and control

Treatment of Uncinaria infections involves the use of anthelmintic drugs. Control measures include regular deworming of pets and disposal of feces to prevent environmental contamination.
