PRESENCE OF ANTIBODIES TO BOVINE LEUKOSIS VIRUS IN HERDS FROM THE CENTRAL AND WESTERN PROVINCES OF CUBA

摘要

The objective of this work was to carry out a serologic study of several adult bovine herds selected by their potentiality for trade. A total of 597 sera samples of healthy adults, coming from Pinar del Río, Habana, Ciudad Habana and Villa Clara was analyzed by an Indirect ELISA. The 25.9% of the samples studied was positive to antibodies against BLV. The results obtained coincide with previous reports for the region, where there is a high prevalence of antibodies to this virus. The study allowed to obtain information about the presence of antibodies to BLV in adults. The results suggest the necessity of carrying out a survey in order to determine seroprevalence in representative herds of the whole country, keeping in mind that the major economic impact of the disease is on the international trade.
