Sensitivity of the multiplex qRT-PCR assay using viral RNAs from HP-H7N9 viruses. (a) Representative amplification plot and standard curves for ten-fold serial dilutions of HP-H7N9 without NAI-resistance mutation strain. (b) Representative amplification plot and standard curves for ten-fold serial dilutions of HP-H7N9 with NAI-resistance mutation strain. The log numbers of live H7N9 viruses (TCID50/mL) are expressed linearly on the x-axis, whereas Ct values are expressed linearly on the y-axis. H7-W, H7-M, N9-W and N9-M are defined the same with Fig. 1
