In the present study, we developed a killed and LPS based Brucella suis vaccine and evaluated the humoral and cell mediated immune response in mice. Brucella suis isolated from field and developed as vaccine. Lipopolysaccharides from B. suis were administered to the nude mice, in addition to killed vaccine from that species whereas mineral oil was used as an adjuvant. The vaccines from B. suis is considered as smooth strain with smooth dissociation. Serum was collected from clotted blood samples of day 0, 7, 14 and 21 from the mice (control, adjuvant, BM-killed, BM-LPS vaccine, BS-killed and BS-LPS groups). In BS-killed and BS-LPS treated groups, the immune response was very significant in BS-LPS group alone. Though, the immune response was lower in BS-LPS vaccine group (p value = 0.0075) in comparison to BS-killed vaccine group (p value = 0.0009), 14 days post vaccination. There is a significant spike on the immune response of the BS-LPS group (p value < 0.0001), 21 days post vaccination. In B. suis vaccinated groups, the TNFα, IFNγ, IL4, IL10 and IL12 expressions were up-regulated in BS-LPS treated animals with a p value of 0.0198, 0.0142, 0.0195, 0.0384 and 0.03 respectively.
