Area of Science:

  • Veterinary Parasitology
  • Livestock Health
  • Anthelmintic Resistance

Background:

  • Anthelmintic resistance in livestock parasites has escalated from a minor issue to a significant industry crisis over three decades.
  • Small ruminant industries in tropical/sub-tropical regions of Latin America face extreme resistance to all broad-spectrum anthelmintics.
  • The cattle industry currently appears less threatened, though resistance in cattle parasites is reported.

Purpose of the Study:

  • To highlight the escalating crisis of anthelmintic resistance in livestock, particularly small ruminants.
  • To question the long-term implications for cattle parasite control and the pharmaceutical industry's role.
  • To emphasize the need for urgent action and research into alternative parasite control strategies.

Main Methods:

Related Experiment Videos

  • Review of existing reports on anthelmintic resistance in sheep, goats, and cattle parasites.
  • Analysis of the pharmaceutical industry's involvement in developing new anthelmintics.
  • Consideration of non-chemotherapeutic control options and grazing management practices.

Main Results:

  • Widespread anthelmintic resistance poses an immediate threat to small ruminant farming, with limited immediate solutions.
  • The pharmaceutical industry has largely withdrawn from developing new anthelmintics due to high costs and small market size for sheep/goats.
  • While cattle parasite resistance is less severe, complacency is unwarranted, and future surveys are needed.

Conclusions:

  • The future for small ruminant farmers facing anthelmintic resistance is bleak, compounded by poor commodity prices and reduced research funding.
  • A significant resistance issue in cattle parasites might incentivize pharmaceutical re-entry, but this is unlikely given market dynamics.
  • Veterinary parasitologists must advocate for the importance of anthelmintic resistance and promote integrated control strategies.
