本文应用ＰＣＲ技术对持续性黄疸婴儿进行巨细胞病毒检测，结果６８例患儿血清中巨细胞病毒（ＣＭＶ）３８例阳性，阳性率为５５．９％；尿中ＣＭＶ４５例阳性，阳性率为６６．２％。ＰＣＲ与病毒分离及其它血清学方法相比，既快速又敏感，尿标本用于ＰＣＲ检测ＣＭＶ－ＤＮＡ取材及处理简便，且较血标本检出率为高［１］。
In this paper, cytomegalovirus was detected by PCR in infants with persistent jaundice. The results showed that 68 cases of CMV were positive in 38 cases, the positive rate was 55.9%. The positive rate of CMV in urine was 45 cases, the positive rate was 66 .2%. PCR is faster and more sensitive than virus isolation and other serological methods. Urine samples are easy to be taken for PCR detection of CMV-DNA and have a higher detection rate than blood samples [1].
