The five viruses, Bombyx mori densonucleosis virus type 1 (BmDNV-1), - type 2 (BmDNV-2), Bombyx mori nuclear polyhedrosis virus (BmNPV), Bombyx mori cytoplasmic polyhedrosis virus (BmCPV), and Infectious flacherie virus (IFV), are the agents causing fetal disease of the silkworm. The aim of this study is to establish a simple and highly sensitive PCR system for detection of all the viruses. A combination of the RT-PCR and the nested PCR was found to be effective to amplify DNA and/or RNA virus genome sequences in a reaction maintaining high sensitivity and specificity. In this report, the primer design and the condition of the PCR for the detection of all the viruses are described.
