Abstract

Four human cytomegalovirus strains with double resistance to both ganciclovir and foscarnet were recovered from acquired immunodeficiency syndrome (AIDS) patients. The four isolates were genetically unrelated and each of them consisted of a single viral population. In addition, for each isolate, UL97 and UL54 open reading frames sequencing showed a single aminoacid change in a conserved domain of each of the two genes.

来自艾滋病患者的四种双耐药人类巨细胞病毒毒株:UL97和UL54开放阅读框的单突变分别导致更昔洛韦和氟膦特异性耐药。
从获得性免疫缺陷综合征(AIDS)患者中分离出4株对更昔洛韦和膦酸钠双耐的人巨细胞病毒。这四种分离株在遗传上不相关,每一株都由单一病毒群组成。此外,对于每个分离物,UL97和UL54开放阅读框测序显示,两个基因的保守结构域各有一个氨基酸变化。
