1987年5月及9月,我们采用ELISA法检测了延边地区的9种野鼠中的Lp_1抗体。结果表明,野鼠的抗体平均滴度为1:10.3±1.3。≥1:80的有黑线姬鼠2只(2/287,0.7％),东方田鼠1只(1/99,1.0％),大仓鼠1只(1/50,0.2％),其中黑线姬鼠、大仓鼠各有1份样本高达1:160,血清抗体效价≥1:80者占0.84％,春秋两季抗体水平无显著差异(P>0.05)。
In May and September 1987, we detected the Lp_1 antibody in nine wild species in Yanbian using ELISA. The results showed that the average titer of voles was 1: 10.3 ± 1.3. There were 2 Apodemus agrarius (2/287, 0.7%) ≥1: 80, 1 (1 / 99,1.0%) vole and 1 large hamster (1 / 50,0.2% Apodemus and hamster had 1: 160 samples each, and the serum antibody titers ≥1: 80 accounted for 0.84%. There was no significant difference in the antibody levels between spring and autumn (P> 0.05).
