Resumo

The efficacy of spores of the ovicidal fungus Mucor circinelloides for preventing infection by Paramphistomum spp. trematodes in grazing cattle has been tested. Three groups of Frisian cows passing eggs of Calicophoron daubneyi in their faeces were employed. Two of the groups (G-F and G-C) were dewormed with Closantel (10 mg / Kg b.w. Endoex, SP Veterinaria, SA, Tarragona, Spain) at the beginning of the study, and group G-C remained untreated as control. Cattle belonging to G-F were given feedstuff with M. circinelloides spores, and the other groups received conventional feedstuff. Calicophoron egg-output was supressed by the administration of the Closantel at 4th and 6th weeks after treatment (wat). The percentages of faecal egg count reduction were 97% (G-F) and 98% (G-T). Eighty-six percent of the treated cattle in both groups did not pass eggs in the faeces at 2 wat. Nevertheless, the cows in G-T shed eggs again from the 10th wat, and values close to the untreated group (G-C) were attained. These results point the need for the application of useful measures against the stages of Paramphistomum in the environment (soil). Manufacturing of feedstuff containing spores of M. circinelloides appears to be a promising solution.
