Several methods for the detection of Borna disease virus (BDV) RNA have been reported, one being the reverse transcription-nested polymerase chain reaction (RT-nested PCR) method. However, due to the possibility of contamination of the cloned DNA in a reaction tube, false-positive results might be obtained by RT-nested PCR. To detect only BDV RNA without anxiety of contamination, we developed an RT-nested PCR system using "mRNA selective PCR kit". Using this system, cDNA of BDV p40 in the plasmid (up to 5 × 107 molecules) was not amplified. BDV specific sequence was amplified from total RNA (more than 50 pg) of MDCK/BDV cells, which were persistently infected with BDV. These results indicate that this mRNA selective RT-nested PCR system can specifically amplify target RNA as distinguished from plasmid contaminated.
