The aims of this research is to determine the ability of sub unit lipopolysacharide(LPS) vaccine of Brucella abortus strain S-19 in mice and goat, including IgM and sub classes IgG antibody humoral response, cellular mediated immune response (IL-2, IFN- γ) in mice, also IgG as humoral immunity, IL-4 and IL-12 as cellular immunity, comparison affectivity with Brucella abortus strain RB-51 vaccine in goat . This research has two steps methods. Step first, 30 Balb C mice were divided into 3 groups and vaccinated subcutaneously, First group injectedB. abortus S-19, second group injected LPS and third group injected sodium chloride solution. Booster vaccination was conducted every two weeks till the eight week after first vaccination. The second step performed vaccinated to 30 goats divided into three groups. First group was injected by subcutaneous LPS 50 µg/ml and second group injected LPS 100 µg/ml and the third group injected with sodium chloride as control. Booster vaccination conducted 2 weeks after first vaccination and second vaccination. Result of the research conferred. Result research, antibody response in mice showed vaccination by LPS of B. abortus S-19 showed higher titer than vaccination by whole cells but inverse cellular response. The both vaccines showed induce subclass antibody response, vaccination by LPS tendency to IgM response but vaccination by Whole cells active vaccine tendency to IgG1, IgG 2a and IgG2b. Response antibody in goat on two weeks after first vaccination, vaccination with LPS of B. abortus S-19, dose 50 µg/ml failed or zero titer IgG response but dose 100 µg/ml was 500response antibody on two weeks after second vaccination by dose 50 µg/ml was 340 but by dose 100 µg/ml was 960, while cellular IL-12 response two weeks after first vaccination by dose 50 µg/ml was 22.88 pg/ml but by 100 µg/ml was 62.15 pg/ml. Response cellular IL -12 two weeks after second vaccination 50 µg/ml was 12.04 pg/ml while by dose100 µg/ml was 130.88pg/ml Cellular immune response IL-4 on two weeks after first vaccination, dose 50 µg/ml showed 55.57 pg/ml but by dose100 µg/ml was 49.35 pg/ ml. Response cellular IL-4 on two weeks after second vaccination by dose 50 µg/ml was 22.17 pg/ml but by dose 100 µg/ml was 143.89 pg/ml Keyword: Vaccine sub-unit LPS of Brucella abortus S-19, Humoral antibody, Cellular antibody
