The ear mite “Psoroptes cuniculi” is the main cause of ear mange, a highly contagious parasitic skin disease in rabbits all over the world. In the current work, a preliminary therapeutic trial to study the effect of the broad use acaricides doramectin and ivermectin on P. cuniculi was performed on artificially infested rabbits. Twenty five adult New Zealand white rabbits were used in this study. The rabbits were assigned randomly into five groups/ 5 rabbits in each group. Each rabbit was experimentally infested with 100 mites/ ear. The first group was designated the positive control group and was not treated. The second and third groups were treated with doramectin 200 and 400 μg/kg bw, respectively. Groups 4 and 5 were treated by dressing with ivermectin in one dose and 2 doses with a 1 week interval. After the therapy, all rabbits were examined microscopically on the 7th, 14th, and 28th day post treatment and the number of live mites (larvae, nymphs, and adults) on each rabbit was counted at the end of the experiment (28th day). The results showed that the rabbits treated subcutaneously with doramectin at a single dose of 200 μg /kg bw showed a very low effect, although there was significant improvement when the dose was doubled to 400 μg /kg bw, with the number of mites counted decreasing significantly. Rabbits treated topically with ivermectin spot-on, a single dose or 2 doses, showed great improvement of the lesion: the number of mites was reduced to zero. In conclusion, this work showed that ivermectin spot-on applied locally on infested ears proves to be more effective against P. cuniculi than doramectin injected subcutaneously. Further trials on ear mange therapeutics in rabbits are to be encouraged.
