The template was serially diluted 10-fold to determine the reaction sensitivity. Finally,seven liver samples of ducks with suspected DHV-1 infection,which were collected from different regions of Jiangsu Province,were detected with this method. The results showed that a DNA fragment of about 360 bp was specifically amplified with the RT-PCR system,and the detection limit was1 fg/μL. The detection rate of clinical samples with this method was 100%. The results revealed that the RT-PCR system which had high specificity and high sensitivity in the detection of DHV-1 was successfully established.展开更多
