Examination by the HI test of 20 representative HEV isolates reveals that only one of them, HEV-18 differs quantitatively from the others. The difference is confirmed qualitatively by the SN test. Both the HI and SN tests demonstrated that all the other HE viruses, though isolated from oubreaks of disease in widely separated areas of Canada over a period of eight years, represent a single strain.
通过血凝抑制试验(HI 试验)对 20 株代表性戊型肝炎病毒(HEV)分离株进行检测发现,其中只有一株 HEV - 18 在数量上与其他分离株不同。该差异通过中和试验(SN 试验)得到定性确认。HI 试验和 SN 试验均表明,所有其他 HE 病毒尽管是在八年时间里从加拿大广泛分隔地区的疾病暴发中分离得到的,但都代表单一毒株。
