The isothermal nucleic acid sequence-based amplification (NASBA) system was applied for the detection of rhinoviruses using primers targeted at the 5' noncoding region (5' NCR) of the viral genome. The nucleotide sequence of the 5' NCRs of 34 rhinovirus isolates was determined to map the most conserved regions and design more appropriate primers and probes. The assay amplified RNA extracted from 30 rhinovirus reference strains and 88 rhinovirus isolates, it did not amplify RNA from 49 enterovirus isolates and other respiratory viruses. The assay allows one to discriminate between group A and B rhinoviruses. Sensitivities for the detection of group B and group A rhinoviruses was 20 and 200 50% tissue culture infective doses, respectively.
基于等温核酸序列扩增(NASBA)系统,使用针对病毒基因组5'非编码区(5'NCR)的引物来检测鼻病毒。测定了34株鼻病毒分离株5'NCR的核苷酸序列,以确定最保守区域,并设计更合适的引物和探针。该检测方法扩增了从30株鼻病毒参考株和88株鼻病毒分离株中提取的RNA,未扩增49株肠道病毒分离株和其他呼吸道病毒的RNA。该检测方法能够区分A组和B组鼻病毒。检测B组和A组鼻病毒的灵敏度分别为20和200 50%组织培养感染剂量。
