我们对脂质体一ＥＶ＿（７６ｐ）（ＶＷ~－）株和ＥＶ株皮下接种动物的抗体滴度进行观察。结果表明：对照组免疫持续长，其ＧＭＴ是实验组脂质体一ＥＬ＿（７６ｐ）（ＶＷ~－）株ＧＭＴ的１．７～３．４倍（Ｐ＜０．０５）。脂质体一ＥＶ＿（７６ｐ）（ＶＷ~－）株对小鼠和家兔的免疫效果均不如ＥＶ活菌苗。
We observed the antibody titers of animals inoculated subcutaneously with liposome-EV 76p (VW ~ -) and EV strains. The results showed that the control group had a long duration of immunization, and its GMT was 1.7-3.4 folds (P <0.05) of the GMT of the liposome EL_ (76p) (VW ~ -) in the experimental group. The effect of liposome-EV 76p VW ~ - strain on mice and rabbits was not as good as that of EV live vaccine.
