Abstract
- Brucellosis is the most common zoonotic disease worldwide and still there is no vaccine for human use. The commercial animal vaccines also have major problems that limit their use. Therefore, there is a need for an effective Brucella vaccine which is multivalent and produces a good protective immunity with minimal disadvantages. Due to their heterogeneous composition and diverse functions, OMVs are promising acellular vaccine candidates against brucellosis. In the present study, the potential of Poly(I:C) or CpG ODN 1826+ Montanide ISA 70 VG adjuvant formulations were evaluated to enhance the immunity and protection levels conferred by OMVs against Brucella challenge in mice. The results indicated that both vaccine regimens were able to induce strong Th1-biased responses and confer protective levels significantly higher than REV.1 live vaccine. With regard to the results, it is concluded that OMVs in either adjuvant can be introduced as a new vaccine candidate against B. melitensis infection.<br />Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2020 Elsevier B.V.
