    • This invention provides a method for determining susceptibility for an anti-viral drug comprising: (a) introducing a resistance test vector Comprising a patient-derived segment and an indicator gene into a host cell; (b) culturing the host cell from (a); (c) measuring expression of the indicator gene in a target host cell; and (d) comparing the expression of the indicator gene from (c) with the expression of the indicator gene measured when steps (a)-(c) are carried out in the absence of the anti-viral drug, wherein a test concentration of the anti-viral drug is present at steps (a)-(c); at steps (b)-(c); or at step (c). This invention also provides a method for determining anti-viral drug resistance in a patient comprising: (a) determining anti-viral drug susceptibility in the patient at a first time using the susceptibility test described above, wherein the patient-derived segment is obtained from the patient at about said time; (b) determining anti-viral drug susceptibility of the same patient at a later time; and (c) comparing the anti-viral drug susceptibilities determined in step (a) and (b), wherein a decrease in anti-viral drug susceptibility at the later time compared to the first time indicates development or progression of anti-viral drug resistance in the patient.
    • 本发明提供了一种用于确定抗病毒药物的易感性的方法,包括:(a)将包含患者来源区段和指示基因的抗性测试载体导入宿主细胞; (b)从(a)培养宿主细胞; (c)测量靶宿主细胞中指示基因的表达; 和(d)比较来自(c)的指示基因的表达与在不存在抗病毒药物的情况下进行步骤(a) - (c)时测量的指示基因的表达,其中测试浓度 在步骤(a) - (c)中存在抗病毒药物; 在步骤(b) - (c); 或在步骤(c)。 本发明还提供了一种用于测定患者抗病毒药物耐药性的方法,包括:(a)使用上述敏感性试验在第一时间确定患者的抗病毒药物敏感性,其中所述患者衍生部分获自 病人约在上述时间; (b)以后确定同一病人的抗病毒药物敏感性; 和(c)比较步骤(a)和(b)中确定的抗病毒药物敏感性,其中与第一次相比后来的抗病毒药物敏感性的降低表明抗病毒药物耐药性的发展或进展 在病人身上
