A study was performed to determine the frequency of Fasciola hepatica. The examination of biliar ducts, colangitis, histologic lesions and eggs in bilis and faeces was evaluated. Seventy eight livers of bovines (bullfighting animals) were evaluated from the Tlaxcala State, Zacatecas State San Luis Potosi State, Mexico State and Jalisco State, in the slaughterhouse of the "Plaza de Toros México". Eighteen bulls from Tlaxcala were positive to Fasciola hepatica (70.8%). Eighteen bulls from Zacatecas represented 48.59% of positive animals to Fasciola. The bulls from San Luis Potosi represented 13.75%, whereas the bulls from Mexico State, 73.15%. The six bulls from Jalisco represented 25%. The general Fasciola mean was: In biliar ducts, 25.6%; with histologic colangitis lesion, 57.6%; with eggs in bilis, 28.2% and eggs in faecal samples, 69.2%. The high frequency of liver flucks in bulls from Tlaxcala, Zacatecas, San Luis Potosi, Mexico State and Jalisco State at the "Plaza de Toros" is very important and needs to be considered when following parasite control programs.REFERENCES
