Webinar Series – Parasitic Diseases in Horses (Part 1) (Recorded October 2020)



The lecture on 'Parasitic Diseases in Horses' gives a broad overview on larval cyathostominosis, small intestinal ascarid impactions, tapeworm-associated colic, and non-strangulating intestinal infarction. It will summarize the scientific evidence behind each of these clinical syndromes and their risk factors, pathophysiology and briefly touch on treatment protocols and often expressed concerns when treating parasitized horses with effective larvicidal anthelmintics.

The webinar on 'Equine parasite diagnostics' will describe currently recommended techniques for determining fecal egg counts and explain relevant diagnostic parameters. Recently emerged or emerging diagnostic techniques such as anti-tapeworm antibody ELISAs and an ELISA for measuring antibodies to encysted cyathostomin larvae will be presented and discussed.

The webinar on 'Principles of anthelmintic therapy' will describe current occurrences of anthelmintic resistance in equine parasites, and briefly discuss mechanisms of resistance development. Evidence-based approaches for parasite control will be described, taking into account important factors such as horse age, climate, seasonality, and levels of anthelmintic resistance.

The seminar on 'Common myths and misconceptions in equine parasite control' will list a number of commonly encountered myths and misconceptions, and outline how the large body of evidence either does not support these, or points in a very different direction.

Panel Discussion – Worms, Glorious Worms – Assessing Disease Risks & Control Recommendations (Part 2) (Recorded 27 October 2020)


Panelists:Martin Nielsen   DVM, PhD, DACVM, DEVPC – DVM, PhD, DACVM, DEVPC, USA
Nikki Walshe   DVM – University College Dublin, Ireland
Jane Hodgkinson   PhD, BSc (Hon) – University of Liverpool, UK
Moderator: Ben Sykes   BSc, BVMS, MS,DACVIM, DECEIM, MBA, PhD – The Univ. of Queensland, Australia


Endoparasites are an important cause of disease in the horse. The widespread emergence of resistance has prompted critical reflection on the role of interval treatment with a move towards ‘test and treat’. However, recent evidence questions the accuracy of ‘test and treat’ strategies for disease mitigation in individual patients. This panel will review the role of endoparasites in disease (incl. geographical differences) and consider what factors should be considered in control recommendations for individual animals and herds. The international panelists will be debating the following topics:

  • The risk of parasitic disease (incl. geopgrahical differences)
  • Larval cyathostominosis – is the risk real?
  • Diagnostics – Usefulnes and limitations in assessing and monitoring individuals/herds
  • Are faecal egg counts reliable?
  • Can we assess tapeworm burden?
  • Can we assess encysted cyathostome burden?
  • Treatment, resistances, associated risks & toxicity
  • Is the use of unlicensed mediations justified and/or safe?
  • Is routine autumn treatment justified?

    DVM, CertAVP, PhD


    More Info

    Nikki Walshe is currently an Assistant Professor in Equine Clinical Studies in UCD. She qualified from UCD school of veterinary medicine in 2011. Then over the next 5 years gained clinical experience and expertise in equine field medicine both in the southern hemisphere and here in Ireland, during which she completed a postgraduate certificate in advanced equine practice (CertAVP). She joined the UCD equine field service in 2016. In this role she provides a clinical service and facilitates the teaching of the equine clinical studies rotation.

    From her experience in the field, Nikki developed a particular interest in the area of equine parasitology, which is the basis of her PhD - the investigation of mechanisms behind parasite associated disease in the horse with a particular emphasis on role of host immunology and the intestinal microbiome- supervised by Grace Mulcahy and Vivienne Duggan. She also recently began a residency training program with the European Veterinary Parasitology College (EVPC) supervised by Grace Mulcahy and Theo de Waal.
