A seroepidemiological survey on bovine leucosis virus was conducted. Serological studies were analyzed by age groups and the sizes of herds. The number of reactors increased gradually with the advance in the age of cattle and the herd size. The highest rate of BIV carriers was found in the ages between 6 and 8 years, and in the size of herds with 20 to 50 heads. Two out of 6 specimens (33.3%) from the reactors showed the typical type C virus with the size of 90 to 110 nm around microvilli and in intracytoplasmic vacuoles
