Prévalence de la Fasciolose des ruminants Dans la région de Sétif

Abstract

Fascioliasis, a disease caused by the parasite of genus Fasciola, has significant economic implications for both humans and animals, and is a major parasitic and zoonotic disease. Although numerous studies have examined the global prevalence of fascioliasis, data on the overall prevalence of the disease and its risk factors in cattle, ruminants and humans remain limited. This retrospective study, conducted at the municipal slaughterhouse in Sétif, Algeria, between 2001 and 2025, aimed to determine the prevalence of fascioliasis in cattle and sheep, as well as its annual infection. Of the 923 871 cattle and 1 054 964 sheep inspected from lesions characteristic of fascioliasis were observed. The annual prevalence was 29,68% (4060 positive cases) in cattle (p < 0,0001) and 2,49% (920 positive cases) in sheep (p < 0,0001). Statistical analysis revealed a highly significant difference between the two species (p < 0,0001), with peak prevalence observed in cattle in 2001 (5,59%) and in sheep in 2006 (0,71%). Fascioliasis is a widespread zoonosis affecting humans and livestock worldwide. There is an urgent need to implement strategies targeting risk factors such as altitude and age to help prevent and control this disease and reduce the incidence of Fasciola infection. Furthermore, given the lack of data in our country, it is necessary to pay closer attention to this infection, additional epidemiological studies should be conducted to improve the quality of the data.
