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. |
