Abstract: Acute respiratory tract infections are of paramount importance in the poultry industry. We developed an xTAG bead assay for the simultaneous detection and discrimination of avian influenza virus (AIV), Newcastle disease virus (NDV), infectious bronchitis virus (IBV) and infectious laryngotracheitis virus (ILTV). The assay lacked nonspecific reactions with other common avian viruses and the limit of detection was 6.75 × 10 <superscript>2</superscript> - 3.52 × 10 <superscript>3</superscript> copies/μL. We examined 60 clinical specimens and found 18 positive for respiratory viruses. Our result demonstrated that xTAG-multiplex PCR method is a high-throughput, rapid, specific and sensitive assay for use in epidemiological studies and clinical detection of avian respiratory pathogens.<br /> (Copyright © 2017 Elsevier Ltd.
