Virus mutants isolated from persistent infections of vesicular stomatitis virus in BHK-21 cells were much less susceptible to interference mediated by the defective interfering particle used to establish the persistent infection. This mutational change occurred as early as 34 days in the persistent infection and continued for over 5 years. The earliest variants showed no oligonucleotide map changes and no difference in the temperature-sensitive phenotype from the original virus, but the later variants exhibited extensive map changes. These results suggest a possible role for defective interfering particles in the selection of the mutants.
从水泡性口炎病毒在BHK - 21细胞中的持续感染中分离出的病毒突变体,对用于建立持续感染的缺陷干扰颗粒介导的干扰作用的敏感性要低得多。这种突变变化早在持续感染的第34天就出现了,并持续了5年多。最早的变体在寡核苷酸图谱上没有变化,温度敏感表型与原始病毒也没有差异,但后来的变体表现出广泛的图谱变化。这些结果表明缺陷干扰颗粒在突变体的选择中可能起作用。
