Summary
New insecticides show promise for controlling zoonotic visceral leishmaniasis (ZVL) transmission in dogs, offering a potential alternative to culling infected animals. These systemic treatments could significantly impact public health by reducing human ZVL incidence.
Area of Science:
- Veterinary Entomology
- Parasitology
- Public Health
Background:
- Zoonotic visceral leishmaniasis (ZVL) poses a significant public health challenge in endemic regions.
- Current control strategies, primarily the culling of infected dogs, have proven insufficient in reducing human ZVL incidence.
Purpose of the Study:
- To evaluate the efficacy of five systemic insecticides (spinosad, fluralaner, afoxolaner, sarolaner, moxidectin) for controlling ZVL transmission in dogs.
- To assess the potential of these insecticides as a novel tool in ZVL control programs.
Main Methods:
- Experimental studies were conducted to confirm the anti-phlebotomine capacity of the selected systemic insecticides.
- The evaluation focused on compounds already in veterinary use for tick and flea control.
Main Results:
- The evaluated systemic insecticides demonstrated anti-phlebotomine capacity, indicating their potential to disrupt ZVL transmission.
- These compounds offer a promising alternative to traditional methods like culling infected dogs.
Conclusions:
- Systemic insecticides represent a promising new strategy for ZVL control programs.
- Further research should compare the benefits and limitations of insecticide-based interventions against current practices to optimize ZVL management.
