采用ＨＩ（血凝抑制试验）法，比较在不同生境中，龙虎山猕猴麻疹病毒抗体阳性率的差异：小群关养组的阳性率为９０．９％；半野生猴组阳性率为２８．３％；野生猴组阳性率为２．４％。不同性别及不同年龄猴麻疹病毒抗体阳性率没有显著性差异（Ｐ＞０．０１）。半野生猴组阳性率逐年递增。对建立无麻疹、Ｂ病毒等病毒感染繁殖种群提出初步意见。
HI (hemagglutination inhibition test) method was used to compare the positive rates of rhesus macaques in Longhushan Mountains in different habitats: the positive rate was 90.9% in the small group and the positive rate in the semi-wild monkey group was 28 .3%; wild monkey group positive rate of 2.4%. There was no significant difference in the positive rate of measles virus among different sexes and different ages (P> 0.01). Semi-wild monkey group positive rate increased year by year. On the establishment of non-measles, B virus and other viral infection breeding population put forward preliminary views.
