Abstract

A duplex RT-PCR assay is reported for the simultaneous detection of avian infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV), the causative agents of major diseases in poultry. The duplex RT-PCR assay optimized showed a detection limit of 10-3 (101 EID50/50m L for IBV and 100.5 EID50/50m L for aMPV, respectively when two viruses were mixed and 10-1 for each one separated (103 EID50/50m L for IBV and 102.5 EID50/50m L for aMPV, respectively. It was specific, sensitive and applicable for the rapid detection of these viruses in clinical samples.
