目的:比较猴 B 病毒血清抗体和病毒 PCR 检测结果,阐明动物感染后病毒在机体内的存在状况.方法:采集成年猴血清和三叉神经组织,首先通过 ELISA 方法检测血清中 B 病毒抗体,然后采用 B 病毒 gL 和 gD 基因引物通过PCR 方法扩增血清 DNA 和三叉神经组织 DNA,比较2种方法的检测结果,并对扩增产物进行序列分析.结果:22份猴血清中,B 病毒抗体呈阳性的有13份(59.1%);PCR 结果显示,抗体阴性动物及所有血清 DNA 模板中均无阳性扩增,但在13份抗体阳性动物的三叉神经组织 DNA 样品中,PCR 阳性4份(30.8%);gL 和 gD 基因扩增条件及产物分析表明,gL 基因的 GC 含量为64.1%,gD 为74.2%,且 gL 的扩增条件和效果明显优于 gD.结论:B 病毒感染猴后,将在部分动物神经节中建立潜伏,而 gL 基因更适合作为分子鉴定的靶标.

Objective: To elucidate the state of monkey B virus(BV) in infected monkey, antibodies and viral DNA in 22 monkeys were detected at the same time. Methods: Sera and trigeminal ganglia(TG) tissue were col?lected from 22 adult monkeys. At first, antibodies to BV in sera were detected by dot immunobinding assay (DIA). Then, DNA was extracted and purified from sera and TG tissue and used as templates for PCR with prim?ers on gL or gD gene of BV. Products of PCR were sequenced and blast in GenBank. Results: In 22 monkey se?ra, 13(59.1%) were confirmed for the presence of antibodies to BV. Results of PCR showed that the virus DNA was present in TG of 4 of the 13 seropositve monkeys(30.8%) tested, but no virus being detected in all sera sam?ples. Sequencing products of PCR showed G+C content in gD gene was very high(74.2%) and middle in gL gene (64.1%). The target of gL gene for PCR was superior to gD gene. Conclusion: Our results indicated that B vi?rus would establish latent in trigeminal ganglia only in part of infected moneys and gL gene locus of BV is a suit?able target for specific and rapid identification of viral infection by PCR technology.
