Validation and optimization of the multiplex qRT-PCR assay using different H7N9 viruses. (a) Representative amplification plot for viral RNAs from LP-H7N9 without NAI-resistance mutation, (b) LP-H7N9 with NAI-resistance mutation, (c) HP-H7N9 without NAI-resistance mutation and (d) HP-H7N9 with NA inhibitor-resistance mutation. H7-W: detection target for universal H7; H7-M: detection target for highly pathogenic H7; N9-W: detection target for universal N9; N9-M: detection target for R292K mutation of N9
