A plaque-reduction assay was used to examine the susceptibility of five phosphonoformic acid-resistant variants of herpes simplex virus type 1 to arabinosylnucleosides and aphidicolin. These viruses were cross-resistant to arabinosylhypoxanthine and to arabinosyladenine when tested in the absence of deoxycoformycin, a deaminase inhibitor. In the presence of deoxycoformycin, no cross-resistance between arabinosyladenine and phosphonoformic acid was observed. The two variants tested were cross-resistant to arabinosylthymine, and all five variants were collaterally susceptible to aphidicolin inhibition.
采用蚀斑减少试验检测了5株1型单纯疱疹病毒膦甲酸耐药变异株对阿糖核苷和阿非科林的敏感性。当在无脱氨霉素(一种脱氨酶抑制剂)的情况下进行检测时,这些病毒对阿糖次黄嘌呤和阿糖腺嘌呤存在交叉耐药性。在有脱氨霉素存在的情况下,未观察到阿糖腺嘌呤与膦甲酸之间存在交叉耐药性。所检测的两株变异株对阿糖胸腺嘧啶存在交叉耐药性,并且所有5株变异株对阿非科林抑制作用均呈现并行敏感性。
