Multiplex RT-PCR for detecting nineteen respiratory viruses

Development of three multiplex RT-PCR assays for the detection of 12 respiratory RNA viruses.

Three multiplex hemi-nested RT-PCR assays were developed to detect simultaneously 12 RNA respiratory viruses: influenza viruses A, B and C, human respiratory syncytial virus (hRSV), human metapneumovirus (hMPV), parainfluenza virus types 1-4 (PIV-1, -2, -3 and -4), human coronavirus OC43 and 229E (HCoV) and rhinovirus (hRV). An internal amplification control was included in one of the RT-PCR as...

Multiplex RT-PCR in the Diagnosis of Human Picornaviruses and Human Respiratory Viruses

Rapid multiplex nested PCR for detection of respiratory viruses.

Respiratory tract infections can be caused by a heterogeneous group of viruses and bacteria that produce similar clinical presentations. Specific diagnosis therefore relies on laboratory investigation. This study developed and evaluated five groups of multiplex nested PCR assays that could simultaneously detect 21 different respiratory pathogens: influenza A virus (H1N1, H3N2, and H5N1); influe...

Analytical Sensitivity Comparison between Singleplex Real-Time PCR and a Multiplex PCR Platform for Detecting Respiratory Viruses

Multiplex PCR methods are attractive to clinical laboratories wanting to broaden their detection of respiratory viral pathogens in clinical specimens. However, multiplexed assays must be well optimized to retain or improve upon the analytic sensitivity of their singleplex counterparts. In this experiment, the lower limit of detection (LOD) of singleplex real-time PCR assays targeting respirator...

Microbiology and Infectious Disease / MULTIPLEX PCR DETECTION OF RESPIRATORY VIRUSES

We evaluated the Hexaplex assay (Prodesse, Waukesha, WI) for the detection of 7 respiratory viruses (influenza A and B, parainfluenza 1-3, and respiratory syncytial virus [RSV] A and B). The Hexaplex assay was performed on 300 respiratory samples during the 1999-2000 respiratory virus season. Results of this assay were compared with shell vial cell culture and/or direct fluorescent antibody sta...
