Viral RNA in HRV16 and HRV1B-infected HNECs at 72 h. a Copy number of HRV1B RNA was higher than that of HRV16 RNA. b LDH activity in HRV16 and HRV1B infected HNECs were not different with that in mock-infected HNECs. c HRV16 and HRV1B RNA were detected in the cytoplasm of HNECs. HRV1B were more abundant than HRV16 (× 200 magnification, scale bar: 50 μm). d Fluorescence intensity was higher in HRV1B than in HRV16. Results are presented as the median with and interquartile range from eight subjects.*p < 0.05, ** p < 0.01 in Wilcoxon signed-rank test
