【摘要】 应用微量细胞培养技术对分离的新疆绵羊梅迪(Magi)病毒CMV—1株作了理化特性的鉴定。研究结果表明,CMV—1株是一个有囊膜的反转录病毒,pH3、60℃30min易于灭活,对胰蛋白酶敏感,二价阳离子无保护作用。这些特性与Magi-visna病毒完全一致。证明CMV—1毒株属反转病毒科,慢病毒亚科,Magi-Visna群。更多还原

【Abstract】 The physicochemical properties of a strain CMV—1 of Maedi virus isolated from sheep in Xingjiang were identified by the technique of micro-cell culture. The result shows that the strain CMV—1 has an envelope and belongs to retrovirus, it is very ease to inactivate in the contion of pH 3 and 60℃ 30 min, very sensitive to trypsin, and there is no protection in the solution of divalent positive ion such as Mgc 12. These properties are absolutely identical with Maedi-Visna virus.更多还原
