Cattle tick control remains a serious problem for cattle farms in Brazil due to the limited success achieved with chemicals. In Brazil, the use of vaccines for tick control associated with the use of chemicals and pasture rotation may open possibilities for integrated control. However, it is important to know whether regional Boophilus microplus strains are sensitive to antibodies produced by the available antigens: antigen preparations Gavac™ and TickGard(PLUS). The aim of this research was to evaluate the performance of two Bm86 antigen vaccine formulation against tick using crossbred bovines in stall test antigen against a regional B. microplus strain. The experiment was carried out in central Brazil (20 degrees 27'S, 54 degrees 37'W). A trial was conducted in stall conditions on crossbred cattle under controlled infestation. Two groups of 16 animals each, homogeneous in weight and sex, were vaccinated with Gavac™ or TickGard(PLUS), two groups of eight animals as control. Challenge was performed on three alternate days, with 5,000 larvae each time, beginning 21 days after the second injection. The antibody response was measured by ELISA and vaccinated animals presented immune response considering IgG levels. The results showed 49.2% and 46.4% protection efficacy for Gavac™ and TickGard(PLUS), respectively.
