应用逆转录套式ＰＣＲ法检测了４８例丙型肝炎、２６例乙型肝炎及１２例甲乙丙丁戊型肝炎病毒感染标志均阴性的肝炎患者血清中的庚型肝炎病毒（ＨＧＶ）ＲＮＡ。结果表明，我国肝炎患者中存在ＨＧＶ感染；ＨＧＶ可单独感染或与其他肝炎病毒混合感染。丙型肝炎患者中，ＨＧＶＲＮＡ的检出率为１０．４％，乙型肝炎患者中的检出率为３．８％，而在甲乙丙丁戊型肝炎标志均阴性的肝炎患者中的检出率为３３．３％，ＨＧＶ与其他肝炎病毒的混合感染可加重肝脏的损害。在我国，ＨＧＶ感染是甲乙丙丁戊型肝炎标志均阴性肝炎的重要病因之一。
Hepatitis G virus (HGV) RNA in sera of 48 hepatitis C patients, 26 hepatitis B patients and 12 patients with hepatitis B and B hepatitis B virus infection were detected by reverse transcription polymerase chain reaction (PCR). The results showed that there is HGV infection in hepatitis patients in our country; HGV can be infected alone or mixed with other hepatitis viruses. Among hepatitis C patients, the detection rate of HGV RNA was 10.4% in hepatitis B patients and 3.8% in hepatitis B patients, whereas the detection rate in hepatitis B patients with hepatitis B and B hepatitis markers was negative Was 33.3%, HGV mixed with other hepatitis viruses can aggravate liver damage. In our country, HGV infection is one of the important causes of hepatitis B and B hepatitis E-negative hepatitis.
