Conteúdo: | Cattle tick control remains a serious problems for cattle farms in Brazil due to the limited sucess achived with chemicals. In Brazil, the use of vaccines for tick control associated with the use of chemicals and pasture rotation may opem  possibilities for integrated control. However, it is important to know whether regional Boophilus microplus strains  are sensitive to antibodies produced  by  the available antigens: antigem preparations Gavac tm and TickGard plus The aim of this research was to evaluate the performance of two Bm86 antigen vaccin formulation against tick using crossbreed bovines in stall test antigen against a regional B.microplus strain. The experiment was carried ou in central Brazil (20° 27' S, 54°37'W). A trial was conducted in stall conditions on crossbred cattle under controlled infestation. Two groups of 16 animals each, homogeneous in weigt and sex, were vaccinated with Gavac tm 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 imune response condidering IgG levels. The results showed 49.2% and 46,4% protection efficacy for Gavac tm and TickGard plus, respectively
