Four hundred and fifty stray dogs were examined and the ticks found were identified according to the species and parasitic stage. A percentage of 52.44% of those dogs were infested with ticks, among these, 93.22% were parasitized by Rhipicephalus sanguineus, 2.97% by Amblyomma aureolatum and 3.81% by both species. R. sanguineus was the more prevalent species among infested animals representing 99.43% of the total number of ticks sampled.
