Difference in tick infestations

Abstract

The aim of this study was to identify the species and parasitic indices of ticks. A flock of 57 individuals (sheep, goats, cattle and dogs) in southern Algeria was studied from March 2019 to February 2020 during monthly visits. A total of 2544 ticks were collected by examining the entire body of the animal. Two tick species were identified: Hyalomma dromedarii (2430 ticks) and Rhipicephalus sanguineus sensu lato (114 ticks). The first species had annual activity and consisted only of adults, while the second species had spring and summer activity and contained both adults and nymphs. At the annual level, the prevalence of infestation, abundance, and intensity were 38.60%, 44.63 and 115.64 ticks per animal, respectively. At the monthly level there were species specific fluctuations, with a peak in activity in September.
