• The usefulness of parasiticide fungi for controlling trematodoses in bovine livestock has been analyzed. Spores of Mucor circinelloides were produced in Petri plates with wheat meal agar and then added to bovine fecal pats containing C. daubneyi eggs. Five doses were assayed, 2.5·104, 5·104, 1·105, 2·105 and 4·105 spores. A percentage of viable eggs ranging from 63% to 81% throughout the study wasobserved. The earliest reduction in the egg viability when using the D3 dosage was reached. The percentages of egg-viability reduced to 50% by 18 days after the treatment of the faeces. Statistically significant difference regarding the percentages of C. daubneyi eggs viability by using the Friedman test was demonstrated (2= 11.731, P= 0.039). These differences were established among the control and the treated groups excluding the D1.
