AbstractTwenty-six capuchin monkeys (Cebus apella) were intramuscularly immunized with 1.0 ml dose of a veterinary inactivated suckling mouse brain rabies vaccine (SMBV) employed in campaigns for rabies prevention in dogs and cats. The animals belonged to three experimental groups previously vaccinated with SMBV and different schemes, were kept in captivity from June, 1996 to June, 1997. All animals received a booster dose. Serum samples were obtained at the 0th, 30 th, 180th and 365 th days and kept stored at -20ºC. The antibodies dosage was carried out through the simplified inhibition fluorescent test. After a booster dose 17/25 (68%) of animals belonged to groups I, II and III, that had neutralizing antibodies above 0.5 IU/ml produced a humoral immune response equal or higher than 0.5 IU/ml, and another five animals that had neutralizing antibodies higher than 0.5 IU/ml kept in these levels. In relationship to longer humoral immune response there is no statistical difference between all groups, G-I x G-II, G-I x GIII, G-II x G-III (p>;0,05). The SMBV induced humoral immune response in capuchin monkeys after a booster dose, producing neutralizing antibodies equal to or higher than 0.5 IU/ml; however, they were short-lasting, being therefore not appropriate as an immunogen to be used routinely in the immunization of these animals which are difficult both to be dealed with and to be kept in captivity.
