Detection of six common human paramyxoviruses in patients with acute febrile respiratory symptoms using a novel multiplex real-time RT-PCR assay.

ABSTRACT: Human metapneumovirus (hMPV), respiratory syncytial virus type A (RSV-A), RSV-B, and human parainfluenza viruses 1, 2, and 3 (HPIV-1, HPIV-2, and HPIV-3) are common respiratory paramyxoviruses. Here, we developed a two-tube triplex one-step real-time reverse-transcription polymerase chain reaction (real-time RT-PCR) and evaluated its performance using clinical samples. The data showed that this novel assay was 100% consistent with the monoplex real-time RT-PCR assay (in-house), which was superior to the commercial routine multiplex-ligation-NAT-based assay. Meanwhile, the clinical nasopharyngeal swabs of 471 patients with the acute febrile respiratory syndrome (AFRS) were analyzed using the established method. The results showed that 52 (11.7%) cases were positive for paramyxovirus. Among
