Resistance of equine small strongyles to benzimidazoles in Belgium.

The research article explores the resistance of equine small strongyles, a type of parasite, to benzimidazoles, a category of drug, in Belgium.

Objective and Methodology

• The purpose of the study was to investigate the resistance of equine small strongyles to benzimidazoles in Belgium. The strongyles are a kind of parasite found in horses.
• The researchers employed two main tools to conduct their study: Egg Reduction Tests (ERTs) and in vitro egg hatch assays. These methods were applied using two types of benzimidazoles, thiabendazole and mebendazole.

Results and Conclusion

• The results from the ERTs and in vitro egg hatch assays showed evidence of the presence of benzimidazole-resistant equine small strongyles in two Belgian studs. In other words, the parasites were no longer being effectively controlled or eliminated by the benzimidazole drugs.
• The findings of this study have significant implications for equine health management, highlighting a need to explore alternative treatments for equine small strongyles. The resistance exhibited by the parasites can lead to ineffective deworming programs and consequently, poor horse health.

Future Implications

• The study underscores the need for ongoing surveillance and research into drug resistance among equine small strongyles. This will equip veterinarians and equine health professionals with knowledge needed to combat these parasites effectively.
• The findings also stress the importance of exploring and developing alternative anti-parasitic drugs that can be effective against benzimidazole-resistant strongyles.
