| Popis: | 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. |
