摘要:

目的:了解屠宰生猪中甲型肝炎的流行情况,探讨猪作为HAV另一宿主和携带者的可能性,以期为人类甲肝的防治提
供一定的理论依据。方法:采用酶联免疫吸附试验(ELISA)法对大理地区屠宰生猪血清中HAV IgG 检测,逆转录-聚合酶链反
应(RT-PCR)对屠宰生猪的全血和胆汁标本进行HAV RNA检测,以甲型肝炎患者的血液和胆汁为阳性对照标本。结果:①屠
宰猪血清样本中检测出HAV 的抗体阳性率为73.3%(374/510);②建立了甲型肝炎病毒的RT-PCR 检测方法;③用RT-PCR
在阳性对照标本中检出HAV RNA;④用RT-PCR 在屠宰猪的全血和胆汁样本中未检出HAV RNA。结论:成功建立起RTPCR
检测待测样本中的HAV RNA 的方法;屠宰猪血清样本中检测出HAV 的抗体阳性率较高;猪是否可以感染人的HAV还
有待于进一步研究。

Abstract:

Objective: To study the epidemic state of the Hepatitis A Virus(HAV)infection in swinery, and to explore the possibility
of swine as another host or carrier of HAV for providing basis for prevention and controlling measures of human HA. Methods: Serum
HAV-IgG of swine in Dali was detected by enzyme-linked immunosorbent assay(ELISA), and HAV-RNA of swine blood and swine
bile samples were tested by reverse transcription- polymerase chain reaction(RT-PCR), with the blood and bile of HAV as positive
control. Results: ①HAV antibody positive rate of the blood samples of swine were detected as 73.3%(374/510); ②RT-PCR method
was built to detect HAV; ③HAV-RNA of positive control samples were detected with RT-PCR; ④HAV-RNA of swine blood and
swine bile samples were not detected with RT-PCR. Conclusion: RT-PCR method is successfully built to detect HAV-RNA. The
antibody positive rate of HAV is rather high in the blood sample of swine. Further research is necessary to demonstrate whether the
swine could infect human HAV.
