【摘要】 实验结果表明：流行性出血热（ＥＨＦ）病毒Ｚ２０株，在３７℃经ｐＨ６．０细胞融合液处理，可引起细胞融合现象。随感染ＥＨＦ病毒的细胞培养天数延长，细胞融合灶逐渐增多。细胞融合的形态特点表现为：首先细胞之间趋向紧密，伴有细胞膜消失，接着核大量聚集，进而变形，最后出现收缩形成融合灶。更多还原

【Abstract】 Epidemic hemorrbagic fever virus.strain Z20 caused cell fusion after exposing to acid environment(pH6. 0). As the infected cells(Vero-E6 cell line) were cultured longer. number of cell fusion foci increased. Morphologicall cell fusion showed that infected cells adhere each other, with disappearance of cell membrance and cluster of nuclei;the muclei became multiform and giant in feature;and finally a complete fusion foci estableshed.更多还原
