A 5′-nuclease real-time reverse transcriptase-polymerase chain reaction assay for the detection of a broad range of influenza A subtypes, including H5N1

A 5'-nuclease real-time reverse transcriptase-polymerase chain reaction assay was developed for the detection of influenza type A and was validated using a range of influenza A subtypes, including avian strains, and 126 nasopharyngeal aspirate samples. The results show the assay is suitable for screening for influenza A infections, particularly in regions where avian strains may be circulating. (c) 2005 Elsevier Inc. All rights reserved.
