摘要
Rapid neuraminidase subtyping of avian influenza viruses from diagnostic samples is crucial considering the existence of permanently emerging and evolving strains. Here we report an easy-to-use, low-cost microarray for neuraminidase subtyping following fragment amplification by a generic, neuraminidase-specific reverse transcription-PCR (RT-PCR). This method enables highly specific characterization with a sensitivity equal to that of matrix gene-specific real-time RT-PCR.
