    • A quantitative assay for HAV comprises infecting at a temperature of from about 30.degree. to about 37.degree. C. a cell sheet with a dilution series of hepatitis A virus and then adding Newcastle disease virus (NDV) to the infected cell sheet and incubating the infected cell sheet in the presence of NDV at an elevated temperature for a time sufficient to permit a cytopathic effect (CPE) to become manifest, this time typically being at least about 4 days and preferably about 5 days. At an incubation temperature of from about 31.degree. to about 33.degree. C. the absence of CPE indicates the presence of HAV and the presence of CPE indicates the absence of HAV. At an incubation temperature of from about 34.degree. to about 36.degree. C. the absence of CPE indicates the absence of HAV and the presence of CPE indicates the presence of HAV.
    • 用于HAV的定量测定包括在约30℃至约37℃的温度下感染具有稀释系列的甲型肝炎病毒的细胞片,然后向感染的细胞片中加入新城疫病毒(NDV)并孵育感染的 细胞片在NDV存在下在升高的温度下持续足以允许细胞病变效应(CPE)变得明显的时间,此时通常为至少约4天,优选约5天。 在约31℃至约33℃的温育温度下,不存在CPE表明存在HAV,而CPE的存在表明不存在HAV。 在约34℃至约36℃的培养温度下,不存在CPE表明不存在HAV,且CPE的存在表明存在HAV。
