Percutaneous ultrasound-guided cholecystocentesis and aspiration of bile were carried out in 176 cows. The same procedures were performed in another 100 cows immediately after slaughter. The bile samples were examined microscopically for eggs of the large and small liver flukes. In addition, a fecal sample from each cow was examined for liver fluke eggs. The findings of both groups were summarised and the results of the fecal and bile sample examinations compared. In all cows the liver was examined for flukes, the results being used as a reference. The study showed that the examination of bile is clearly a more reliable method of diagnosing liver fluke infections than the microscopic examination of feces
