Investigation of flukes (Fasciola hepatica and Paramphistomum sp.) parasites of cattle in north-eastern Algeria.

Fasciolosis due to Fasciola hepatica is one of the dominant pathologies in Algeria. On the other hand, gastroduodenal paramphistomosis are little studied and little known. Our work consisted of an epidemiological survey in the Souk-Ahras region to investigate these two parasites in cattle. Regarding the epidemiological investigation, it took place in the Souk-Ahras abattoirs, where 530 cattle were inspected for the presence of both parasites. The prevalence of fasciolosis was 12.3%, while the prevalence of paramphistomosis was 7.9% in cattle. Elderly animals were more infected than those under two years of age and females were more infected than males and for both parasites. Therefore, it is important to take into consideration both parasitic diseases and appropriate control measures are strongly recommended to improve cattle productivity.
