摘要 目的 探讨感染四项阴性献血者去白细胞悬浮红细胞感染EBV的情况及基因分型。方法 采用荧光PCR技术对500例去白细胞悬浮红细胞血袋进行EB病毒核酸定量,统计其感染率,并根据EBV的EBNA2与EBNA3C基因连锁多态性及BamHI基因某些片段的保留与缺失通过PCR联合限制性片段长度多态性(RFLP)的检测对EBV阳性标本进行A/B、F/f、C/D分型,分别统计出各型别的检出率。结果 500例血液制品样本中共有44例检测到有EB病毒DNA拷贝,阳性率为8.8%(44/500)。其中A/B分型中A型检出率为36.36%(16/44),B型检出率为63.64%(28/44),A型和B型混合感染未检出。F/f分型中F型检出率为79.55%(35/44),f型的检出率为20.45%(9/44),无两型混合感染。C/D分型中C型检出率为70.45%(31/44),D型检出率为29.55%(13/44),无两型混合感染。结论 感染四项阴性献血者输血时有EBV感染的可能,EBV阳性的样本中,多数以B、C、F型EBV感染为主。
