Susceptibility testing of herpes simplex type 1 (HSV-1) and type 2 (HSV-2) viruses to cytosine arabinoside (Ara-C) has been standardized under conditions of optimal reproducibility, susceptibility, and simplicity. Standard conditions were defined as virus inoculum of 10(1.5) to 10(2.5) TCID(50), WI-38 strain of lung fibroblasts, 2-day incubation, and observation of virus cytopathic effect after staining by the May-Greenwald-Giemsa method. The variability of minimum inhibitory concentration (MIC) of cytopathic effect was fourfold within each test and sixfold in successive assays. MIC values of all seven tested HSV-1 strains were in the range of 0.25 to 0.75 mug per ml, whereas four of nine HSV-2 strains had MIC values of 0.9 mug per ml and greater. A similar method can be used for assay of virus inhibitory titers of body fluids.
对单纯疱疹病毒1型(HSV - 1)和2型(HSV - 2)进行阿糖胞苷(Ara - C)敏感性试验,已在最佳重复性、敏感性和简易性条件下实现标准化。标准条件定义为:病毒接种量为10(1.5)至10(2.5)半数组织培养感染剂量(TCID(50)),WI - 38肺成纤维细胞株,培养2天,并采用美-格-姬氏染色法染色后观察病毒细胞病变效应。每次试验中细胞病变效应的最低抑菌浓度(MIC)变化为4倍,连续试验中为6倍。所有7株受试HSV - 1菌株的MIC值在每毫升0.25至0.75微克范围内,而9株HSV - 2菌株中有4株的MIC值为每毫升0.9微克及更高。类似方法可用于检测体液的病毒抑制效价。
