为了对庚型肝炎病毒（ＨＧＶ）的进一步研究提供基础，设计了针对ＨＧＶ基因组５’－ＮＣＲ区的引物，建立了ＲＴ－ＰＣＲ检测ＨＧＶ核酸的方法。通过对１１６例肝炎患者血清中ＨＧＶ－ＲＮＡ检测，分别在乙肝、丙肝患者血清中各检出２例ＨＧＶ－ＲＮＡ阳性，阳性率分别为４．７％和８．７％。甲肝患者血清中未检出ＨＧＶ－ＲＮＡ。
In order to provide a basis for the further study of hepatitis G virus (HGV), primers designed for the 5’-NCR region of HGV genome were designed and a method for detecting HGV nucleic acid by RT-PCR was established. HGV-RNA was detected in serum of 116 patients with hepatitis B, and 2 cases of HGV-RNA were detected respectively in serum of hepatitis B and hepatitis C patients. The positive rates of HGV-RNA were 4.7% and 8.7% respectively. HGV-RNA was not detected in the serum of hepatitis A patients.
