ABDUL-HADI, Salha et al. Study of human hepatic fasciolosis and intestinal parasitosis in the Mesa Arriba Village, Carache Municipality, Trujillo State, Venezuela. Rev. Soc. Ven. Microbiol. [online]. 2009, vol.29, n.2, pp.128-132. ISSN 1315-2556.

A clinical-epidemiological study to determine the occurrence of human hepatic fasciolosis and intestinal parasitosis was done at the Mesa Arriba Village, Carache Municipality, Trujillo State, Venezuela, area which has been described as endemic for bovine fasciolosis and where two isolated cases have been reported in humans. The study included 98 persons who, after previously signing an informed consent form, answered an epidemiological survey and were physically examined and submitted to the following laboratory tests: complete hematology, aminotransferase, and coproparasitology and serology; ELISA using Fasciola hepatica adult excretion-secretion antigen (AFhES) and “Western Blot” (WB). Based on the results obtained, it was found that 88.8% of participants had consumed wild watercress (Rorippa nasturtium aquaticum) and 59.2% had contact with bovine cattle. The coproparasitological study showed that 47.9% had some type of intestinal parasite: 20.4% corresponded to helmints, 15.3% to protozoa, and 12.2% mixed infections. There were no Fasciola hepatica eggs; 18.4% of the individuals showed eosinophilia. The ELISA test gave one positive serum with non-specific WB-AFhES bands. Specific anti-intestinal parasite treatment was indicated. Human fasciolosis was not demonstrated in this study, in spite of finding favorable factors for this infection, but is represents and approximation to its epidemiological study at Trujillo State.
