[Main features of helminth parasitism in cattle in Ituri (Haut-Zaire). III. Geographic distribution and prevalence of the main helminths].
A necropsic survey, carried out in eleven slaughterhouses in Ituri (Haut-Zaïre), has permitted to define the geographic distribution and prevalences of the main cattle helminths. Trematodes, except the paramphistomes, had a very heterogeneous distribution. Prevalence of Fasciola gigantica ranged from 9 to 72% according to the sites, but these variations were not linked to topographic or climatologic parameters. The infection with Schistosoma bovis was much variable as well (12.5 to 72%) and seemed absent from the central high altitude area. The occurrence of Dicrocoelium hospes was restricted to the northern part of Ituri with a moderate prevalence of about 35%. By contrast, nematodes had a fairly homogeneous distribution in Ituri. Prevalences were high for gastro-intestinal strongyles of the following genera, Haemonchus, Cooperia and Oesophagostomum (over 60%). Cysticercosis (Cysticercus bovis) occurred in 10 to 14% of cattle in the middle and south areas of Ituri whereas the north areas were nearly free.
