Plain-English summary

A group of beagle dogs was treated with a new oral medication called afoxolaner to see how well it worked against ticks. The dogs were infested with ticks before treatment, and after taking afoxolaner, it eliminated nearly all the ticks and kept them away for weeks. The treatment showed over 98% effectiveness in controlling the ticks for almost a month. This means that afoxolaner is a strong option for keeping dogs tick-free.

Abstract

Efficacy of afoxolaner, a novel isoxazoline insecticide/acaricide, against Ixodes scapularis was evaluated in a laboratory study. One day prior to treatment, beagle dogs (n=16) were infested with 50 unfed wild adult ticks. Repeat infestations were performed weekly for four additional weeks. The number of live ticks remaining on each dog was determined 48 h after treatment and after each subsequent infestation. A single oral treatment with a dose approaching the minimum effective dose of afoxolaner (2.5mg/kg) eliminated the pre-existing infestations of I. scapularis ticks and controlled weekly re-infestations, with efficacy between 98% and 100% recorded until Day 23 and 94% at Day 30.
