    Abstract:   Objective   To establish a fourmultiplex RT-PCR assay for rapid and accurate detection of 2013novel avian influenza A (H7N9) virus in throat-swab specimens ofpatients with fever.   Methods   The universal primersfor amplifying the M gene were designed for detection of influenzaA viruses. Two pairs of specific primers of HA and NA gene weredesigned to detect the 2013 novel A (H7N9) influenza virus. Theanthropogenic housekeeping gene of beta-actin was selected andprimers were designed as quality control for throat-swab samples.The reaction system of one-step four multiplex RT-PCR assay wasestablished by optimizing the experimental conditions. Thecommercially available real-time fluorescent RT-PCR kits were usedto validate this method.   Results   The one-step fourmultiplex RT-PCR assay for screening of 2013 novel avian influenzaA (H7N9) virus was developed successfully.   Conclusion  The new method is simple, practical, low-cost and very suitable forrapid detection of 2013 novel avian influenza A (H7N9) virus.
