ABSTRACT

Este trabalho teve como objetivo avaliar a eficiência de duas vacinas inativadas contra agalaxia contagiosa contendo adjuvante oleoso e aquoso. Para tanto, foram utilizados 73 caprinos, agrupados em dois experimentos. No experimento I, para avaliar a inocuidade das vacinas, foram utilizados 15 caprinos, subdivididos em três grupos de cinco animais cada, sendo que o grupo A1 foi imunizado com a vacina aquosa, o grupo B1 com a vacina oleosa e o grupo C não imunizado, foi o controle. No experimento II, para avaliar a resposta imune foram utilizados 58 caprinos, subdivididos em dois grupos, sendo o grupo A2, com 28 animais imunizados com a vacina aquosa e o grupo B2, com 30 animais imunizados com a vacina oleosa. Os animais do experimento II receberam uma terceira dose, 180 dias após a segunda dose vacinal. Os níveis de anticorpos foram determinados por ELISA indireto, realizado no dia de cada vacinação e 30 dias após a segunda dose (experimento I) e 30 dias após a terceira dose vacinal (experimento II). Os animais do grupo B1 e B2 (vacina oleosa) apresentaram níveis de anticorpos estatisticamente superiores (P<0,05) quando comparados aos dos grupos A1 e A2 (vacina aquosa) nos dois experimentos.


This study aimed to evaluate the efficacy of two inactivated vaccines against contagious agalactia containing adjuvant oily and watery. For this, 73 goats were divided in two experiments. In the experiment I was verified the vaccine safety and 15 goats were divided into three experimental groups of five animals each. A1 and B1 groups were immunized with vaccine containing either aluminum or oil, respectively, and group C was the control group without immunization. In the experiment II, the immune response against the vaccines was evaluated by immunization of 58 goats that were divided in to two groups: group A2, 28 animals were immunized with the aluminum based vaccine; and group B2, 30 animals were immunized with the oil based vaccine. In the experiment II, the animals received a third dose on 180 day after the second dose. Antibody levels were determined by indirect ELISA from ssamples collected on vaccination days and on 30 day after the second dose (Experiment I) and on 30 day after the third dose (Experiment II). The animals from B1 and B2 groups (oil based vaccine) demonstrated higher antibody levels (P<0.05) than A1 and A2 (aluminum based vaccine) in both experiments.
