New Record of Rhipicephalus fulvus (Neumann, 1913) from Goats and Sheep in Northeastern Algeria After more than a Century.

Purpose: Tick diversity in Algeria has garnered increasing interest due to its implications for animal health and zoonotic diseases. Recent reports of abnormal ulcerative lesions in goats and sheep in the Cheria region of northeastern Algeria have raised concerns about a potential association with tick infestations. The aim of this study is to hypothesize the potential involvement of ticks in these unusual lesions.

Materials And Methods: A total of 52 tick specimens were collected from the affected animals, comprising 24 adult males, 24 adult females, and four engorged females. A morphological examination was performed to identify the tick species.

Results: The morphological analysis identified the non-engorged ticks as Rhipicephalus fulvus. The observed ulcerative lesions were likely caused by reactions to the tick's saliva. Notably, this finding marks the first recorded presence of R. fulvus in Algeria since its original description by Neumann in 1913.

Conclusion: Identifying R. fulvus highlights its reemergence in the region and suggests a potential impact on livestock health. This discovery underscores the need for enhanced tick surveillance and further studies to understand the tick's origin, distribution, and role in animal health.
