Etude des Tiques Ixodidae des petits ruminants dans la région de Tiaret, 2020

Besides their direct pathogenic role (spoliation of blood, cutaneous lesions), they can inoculate haemolysis molecules, anti-coagulants sometimes toxics and they can also act as vectors of many pathogens (virus, bacteria and protozoa) responsible for potentially serious infections in humans and several animal species. The present study was conducted in the Tiaret region with the aim of determining the frequency of infestation and identifying the tick species encountered in small ruminants. Small ruminants had an overall frequency of 53.73%. By species, goats were more infested with 75% against 48.11% recorded in sheep. The average overall parasite load was 5.51 T/A and 21.64 T/A in sheep and goats, respectively. The preferred attachment site for ticks has been the ears in sheep. In goats, anal localization was predominant. Rhipicephalus sanguineus was the most dominant species in sheep in the study region, with a percentage of 66.89%, followed by Rhipicephalus turanicus with a rate of 16.72% and Rhipicephalus bursa with 16.39%. Rhipicephalus bursa was the most dominant species in goats with a percentage of 89.44%, followed by Rhipicephalus sanguineus with a rate of 9.9%. However, Rhipicephalus turanicus and Hyalomma lusitanicum recorded only a rate of 0.49% and 0.17% respectively. The rates of infestation and the number of ticks collected are high, which should prompt us to conduct in-depth studies on the diseases transmitted by these ticks and the use of acaricides for the treatment and prevention of infestation by these arthropods.
Keywords: Sheep, goats, ticks, Ripicephalus spp, Hyalomma, Tiaret.
