Global goals

  • 12. Responsible consumption and production

Short summary

Reindeer ar primarily treated with anthelmintics due to the warble fly larvae and the throat bot. Even though this treatment is not aimed at the gastrointestinal parasites, they are still sensitive the the drugs.

The goal with this pilot project is to investigate: 

  • How anthelmintic treatment (with the substance ivermectin) to counteract worm infections affects reindeer intestinal worm parasites
  • Which species of intestinal parasites infect reindeer in Sweden
  • How common the reindeer brainworm is
  • What is the resistance status to ivermectin after many years of anthelmintic treatment

This project address gaps in the knowledge chain because anthelmintic resistance is increasing in many animal parasites, making the importance of effective treatment methods more urgent.
