ABSTRACT
To screen and identify the possible pathogen of the firstly confirmed human case of avian influenza A in Beijing, the throat swabs and tracheal aspirates of this case were collected and the H5N1 viral nucleotide was tested with real time RT-PCR. The certification of result, screening of other pathogens in respiratory tract and sub-typing of influenza viruses were made by using re-sequencing microarray. It was found that the H5N1 viral nucleic acid was positive in the tracheal aspirate of this case by means of detection with real time RT-PCR and the specific sequence of the non-structural protein (NS) gene of H5N1 virus was obtained through the detection with re-sequencing clip. Through the comparative study with the sequence in Genbank, it was proved to be the H5N1 nucleic acid of avian influenza viruses and excluded the possibility of infections with 30 subtypes of influenza viruses and 33 other respiratory tract pathogens. It is apparent that the pathogen detection with re-sequencing clip shows the high sensitivity and specificity and it plays an important role in the pathogen screening and identification for the firstly confirmed human case of avian influenza A in Beijing.
