Abstract:
To identification the immunization activation of recombinant Leptospira gene vaccine from many-siden MethodsThe guinea pigs were immunized with recombinant Leptospira gene vaccine [plasmid vector pT7-7 was negtive control ,inactivated whole cell vaccine (WCV) was positive control]. Then spleen cells were taken out. Particularity lymphocyte transformation test(LTT),IL-2 and IL-6 activation of these spleen cells were determined by MTT and 3H-TdR respectively. Results1)The Relative transformation index of gene vaccine group was significance higher than pT7-7 group (vaccin group: 2. 19±0. 18, pT7-7 group 1.42±0. 27 ( P＜0. 005 ); 2 ) the activation of IL- 2 and IL- 6 from recombinant gene vaccine group waw significance stronger than pT7-7 group (vaccine group IL-2:34. 8±3.11,IL-6:94. 6±6.03, pT7-7 group IL-2:20. 4±3. 05,IL-6: 67±6.28), (P＜0. 005). Conclusion1) The activation of Th1 and Th2 lymphocyte cell were increased in the guinea pigs with gene vaccine immunized. It suggested the recombinant Leptospira gene vaccine could elicit an extremely strong immunization effect of T-cell cooperate with B-cell and the gene vaccine was equal the WCV(P＞0. 05)but the gene vaccine sideeffect was small and the applying prospect was good.
