Summary
# Editorial Summary Equine tapeworm control presents a particular diagnostic challenge within modern targeted treatment strategies, as faecal egg count analysis—the standard tool for monitoring most helminth infections—lacks sensitivity for Anoplocephala species and cannot reliably guide treatment decisions. Lightbody and colleagues evaluated a commercially available saliva-based immunological test in UK horses to determine whether it could accurately identify tapeworm infection, offering practitioners an alternative diagnostic approach. The saliva test demonstrated strong diagnostic accuracy for detecting equine tapeworm infections, providing reliable results that faecal analysis cannot match and enabling farriers, veterinarians and stables to implement selective treatment protocols based on individual infection status rather than blanket anthelmintic dosing. Given ongoing concerns about anthelmintic resistance and the need to preserve drug efficacy through reduced and more judicious use, this diagnostic capability allows practitioners to target tapeworm treatment only where warranted, minimising unnecessary medication whilst maintaining effective parasite control. Incorporating saliva-based testing into routine parasite monitoring programmes represents a practical, evidence-based refinement to helminth management that aligns with contemporary best practice in equine health.

Practical Takeaways
- •Consider using saliva-based diagnostics for tapeworm detection as a more reliable alternative to faecal egg counts when deciding which horses need treatment
- •Implementing targeted selective treatment based on diagnostic testing helps reduce unnecessary anthelmintic use and mitigates resistance development
- •Adopt diagnostic-driven parasite management protocols rather than blanket treatment approaches
Key Findings
- •Saliva-based diagnostic test accurately diagnoses horses with tapeworm infection
- •Faecal egg count analysis has limitations for informing tapeworm treatment decisions
- •Targeted selective treatment strategies using diagnostics can reduce anthelmintic use in equine populations
