An update on cyathostomins: anthelmintic resistance and diagnostic tools.

Abstract: Cyathostomins represent a potential cause of equine morbidity and have become the main focus of endoparasite control in managed horses. All grazing horses are at risk of infection with cyathostomins; therefore, the application of appropriate management measures is essential. Anthelmintics currently comprise the main method of control for equine nematodes and the ready availability of these products in some countries has resulted in their use becoming dissociated from veterinary involvement. This is concerning given the levels of anthelmintic resistance that have been recorded in cyathostomin populations. It is important that veterinarians re-establish control over the implementation of parasite control programmes, a major objective of which should be the preservation of anthelmintic efficacy. This article details the principles of cyathostomin control in horses with particular reference to anthelmintic resistance, and the use and interpretation of diagnostic tests for detecting cyathostomins and identifying anthelmintic resistance.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The study focuses on cyathostomins, a type of parasite in horses, and the growing resistance of these parasites to anthelmintics, which are medicines used to destroy them. It emphasises the need for better control and management of these parasites, with a focus on diagnostic tools and an understanding of anthelmintic resistance.

About Cyathostomins

  • Cyathostomins are endoparasites that affect horses. They are potentially harmful and are now the primary concern when it comes to parasitic control in managed horses.
  • All horses that graze are at risk of being infected by cyathostomins, which makes their effective management an essential task.

Use and Misuse of Anthelmintics

  • Anthelmintics, drugs that are often used to treat nematode infections in horses, have increasingly become the preferred method to control these parasites.
  • In some regions, these types of medicines are readily available, which has led to their indiscriminate use without proper veterinary care.
  • One major difficulty associated with this scenario is the development of resistance in the cyathostomin populations to the anthelmintics, reducing the efficacy of these drugs.

Need for Veterinary Oversight

  • The study underlines the prevalence and risk of anthelmintic resistance and highlights the importance of veterinary control in the application of parasite control programmes.
  • One of the large goals of such programmes should be preserving the efficacy of the anthelmintics, which have become less effective due to increasing resistance.

Diagnostic Tests and Resistance Identification

  • Finally, this article explains the role and interpretation of diagnostic tests in the detection of cyathostomins and the recognition of anthelmintic resistance.
  • Such detection and identification are critical components in the management and control of equine nematode infections and in the successful design and implementation of parasite control programmes.
