title: Adjuvanticity effect of sodium alginate on subcutaneously injected BCG in BALB/c mice.
abstract: Bacillus Calmette-Guerin (BCG) is the only available vaccine against tuberculosis. The research for an improved vaccine is currently a very active field of investigation. In the present study, adjuvanticity effect of sterile sodium alginate on subcutaneous BCG vaccination in BALB/c mice was investigated. Mice were vaccinated subcutaneously with BCG plus alginate and the immune response and protective effect were compared to those of mice vaccinated with BCG alone by the same route. Proliferative and delayed-type hypersensitivity responses, IFN-gamma, specific anti-mycobacterium total IgG, IgG1 and IgG2a production were significantly higher in mice immunized subcutaneously with BCG plus alginate in comparison with results of mice immunized with BCG alone. Following systemic infection with BCG, mice vaccinated with BCG plus alginate had lower mean bacterial count compared to those vaccinated with BCG alone. The immune responses induced by subcutaneous administration of BCG plus alginate were significantly better than the responses induced by standard BCG vaccination.
