| Abstract: | The study was aimed to establish a rapid one-step duplex RT-PCR detection method,which could be used to identify and diagnose PEDV and TGEV in clinical diarrhea cases.According to the gene sequences of PEDV and TGEV from GenBank,two pairs of specific primes were designed.Through optimizing and selecting of the best reaction conditions,we finally pinpointed the duplex one-step RT-PCR detection method with strong specificity,which could detect 1×10-5 diluent degree of vaccine. Suspected samples,which were collected from different pig farms in 2015,were detected of PEDV with 100% positive rate.The method was rapid,high sensitivity and specificity,which could be used for clinical detection of PEDV and TGEV,and also for epidemiological investigation. |
