title: Effect of ivermectin on the brown dog tick, Rhipicephalus sanguineus.
abstract: Ivermectin (Ivomec) proved to be effective in controlling R. sanguineus. All brown dog ticks infesting the treated dogs (subcutaneous injections) with 1.5 ml or 2 ml/50 kg dropped off within 4 or 3 days respectively. The dropped off ticks were completely inactive and died within one day or two. Ticks exposed to filter papers impregnated with 100 micrograms/ml (66.67%) died within four days. A dose of 1.5-2 microliters/50 kg eradicated Toxocara canis infection in four dogs, and caused shrinkage of Dipylidium caninum gravid segments in three. A general discussion was given with special reference to the contraindications and side effects of ivermectin particularly for human usage.
