Abstract

Cell surface proteins of Brucella melitensis Rev-1 (BCSPs) were analysed for their protective efficacy in a passive transfer assay. Spleens of BCSPs immunized donor BALB/c mice were removed aspetically and the T-cell suspensions were made. The antisera, splenic T-cells (3×107 viable cells) and mixed spleen cells (T+B lymphocytes as 3×107 viable cells) from donor BALB/c mice were injected intravenously in recipient BALB/c mice. After 2 hrs of this injection the mice of recipient groups were challanged with 5×104 Colony forming units (Cfu) of B. melitensis S16M. The highest (1.96 log units) protection against challenge was induced by transfer of serum followed by mixed spleen cells and T-cells transfer with 1.46 and 1.07 log units, respectively.
