Abstract: Objective To know the real situation of BV infection in rhesus monkeys so as to decrease effectively the infection rate.Methods The serums from 629 rhesus monkeys were tested by BV ELISA kit.Results 350 serums were serologically positive for BV antibody,10 serums were serologically doubtful for BV antibody,and the others were all serologically negative for BV antibody.Conclusion BV infection rate was 89% in the monkeys of the age of 11 years and over the age of 11 years,the rate was 39.2% in the monkeys of the age of 3～10 years,and the rate was 7.6% in the monkeys less than the age of 2 years.The infection rate was increased with age.

摘要： 目的摸清B病毒(BV)感染现状,从而有效降低BV在恒河猴群中的感染率。方法采用ELISA方法对恒河猴血清进行抗体检测。结果检测样品629份,其中350份呈BV抗体阳性,10份血清呈BV抗体可疑,其余血清为抗体阴性。结论种猴(≥11周岁)BV感染率89%;青年猴(3~10周岁)BV感染率39.2%;幼龄猴(≤2周岁)BV感染率7.6%。随着年龄的增长,恒河猴群中BV感染率越高。
