Summary
# Editorial Summary Cyathostomins and *Anoplocephala perfoliata* represent significant threats to equine health across diverse populations, yet conventional faecal egg count methods fail to capture the full picture of an individual horse's parasitic burden. This Italian research compared traditional coprological diagnostics with antibody-based serological testing to evaluate infection prevalence and identify risk factors, providing a more nuanced understanding of actual infection levels versus egg-shedding patterns. The findings demonstrate that serological approaches reveal substantially higher infection rates than faecal analysis alone, suggesting many horses harbouring substantial parasite populations whilst producing minimal or no detectable eggs—a critical distinction for practitioners relying solely on egg counts to inform treatment decisions. Specific risk factors influencing infection susceptibility were identified across the study population, enabling more targeted intervention strategies. These results argue for a shift towards integrated diagnostic protocols incorporating antibody detection, particularly when managing horses in endemic regions or those with suspected subclinical infections, and highlight the limitations of faecal-only surveillance for accurate epidemiological assessment and individual animal risk stratification.

Practical Takeaways
- •Consider using antibody-based diagnostic tests alongside or instead of faecal egg counts to better understand actual parasite burdens in your horses
- •Coprological testing alone may underestimate infection status and parasite load in individual animals
- •Multiple diagnostic approaches may be needed to comprehensively assess internal parasite infection risk in equine populations
Key Findings
- •Coprological techniques commonly used for assessing helminth egg shedding do not provide information about individual total parasite burden
- •Antibody-based tests provide superior information on infection levels within individual horses compared to traditional egg-counting methods
- •Study evaluated prevalence of cyathostomins and Anoplocephala perfoliata infections in Italian horse populations
