Resumo em inglês
Bovine brucellosis is a zoonosis that play important economic role for causing reproductive losses on animal species that are affected. In 2001, in Brazil, Brazilian National Program for the Control and Eradication of Bovine Brucellosis and Tuberculosis was created. One of the main action proposed by the program is vaccination of female between three to eight months of age by B19 strain. Later, in 2007, were defined the roles for RB51 strain use in females older than eight months, and in herds that are in outbreak situation. It is known that this measure, if used, would short the time needed for bovine brucellosis reduction. In order to estimate the magnitude of this reduction, as well as to measure the accumulated of protected animals for brucellosis prevalence decrease, a mathematical model was done associating protection by B19 in 80% of heifers, to protection by RB51 in 10, 40 and 80% of other females. For simulations, states that presented brucellosis prevalence superior than 2% were considered. Comparing these scenarios was possible to conclude that the time needed to reduce prevalence to 2% were similar between 40 and 80%. This turns the former alternative economically more interesting, once it will cover lower number of protected animals. Considering Goiás State, that presents prevalence of 3.01% and a amount of 8336,632 female bovine, protection of 80% of heifers by B19, along protection of 40% of other females by RB51, would make prevalence reach 2% in four years, with a total of 1302,130 protected animals. Relative to Mato Grosso State, that has the major prevalence, 10.25%, and 8377,433 female older than 24 months of age, were observed that brucellosis frequency would reduce to 2% in 15 years in case of 40% of female protected by RB51, resulting in an amount of 1656,098 animals. In comparison with the use of B19 as single preventive measure, time to reduce prevalence to 2% will reduce from seven to four years in Goiás, and from 22 to 15 years in Mato Grosso. Moreover, determination of accumulated of protected animals allows that RB51 use would be economically evaluated
