Endoparasites are parasites which live inside a host and generally inhabit areas such as the gut, lungs, heart and blood vessels.

Endoparasites are important because:

  • They can cause severe disease to the host
  • Many are highly resistant to environmental degradation and can cause widespread contamination of the environment if not controlled
  • They may be zoonotic or transmit zoonotic infections
  • They may interfere with the human – animal bond
  • Their management is part of maintaining healthy pets


Endoparasites belong to one of two types:


Helminths (Worms)
