从抗体阳性的甲型肝炎接触者粪便中分离出一株甲型肝炎病毒

ONE TYPE OF HAV FROM THE STOOL OF VIRAL HEPATITIS A CONTACTOR OF THE ANTIBODY POSITIVE

几年来,国内外已相继用组织培养法分离多株甲型肝炎病毒(HAV),并已证实了甲型肝炎患者及亚临床型感染在传染本病中的重要性。但HAV在流行点的正常人群中存在短期携带的问题还尚未见报道。本文采用人胚肺二倍体细胞(2BS)从甲型肝炎接触者粪便中分离出一株HAV,并经免疫电镜、免疫荧光及参比血清鉴定等证实。现将结果报告如下。

One strain HAV was directly isolated from the faces which were col- lected from HAV contactors of the antibody positive with 2BS. This strain HAV was identificated by immunofluorescent technique, immuno-electronic microscope and serology.
