The polymerase chain reaction [PCR) was used to amplify a portion of the nucleoprotein [NI gene of infectious hematopoietic necrosis virus (IHNV). Using a published sequence for the Round Butte isolate of IHNV, a pair of PCR pnmers was synthesized that spanned a 252 nucleotide region of the N gene from residue 319 to residue 570 of the open reading frame. This region included a 30 nucleotide target sequence for a synthetic oligonucleotide probe developed for detection of IHNV N gene messenger RNA. After 25 cycles of amplification of either messenger or genomic RNA, the PCR product (DNA) of the expected size was easily visible on agarose gels stained with ethidium bromide. The specificity of the amplified DNA was confirmed by Southern and dot-blot analysis using the biotinylated oligonucleotide probe. The PCR was able to amplify the N gene sequence of purified genomic RNA from isolates of IHNV representing 5 different electropherotypes. Using the IHNV primer set, no PCR product was obtained from viral hemorrhagic septicemia virus RNA, but 2 higher molecular weight products were synthesized from hirame rhabdovirus RNA that did not hybridize with the biotinylated probe. The PCR could be efficiently performed with all IHNV genomic RNA template concentrations tested (1 ng to 1 pg). The lowest level of sensitivity was not determined. The PCR was used to amplify RNA extracted from infected cell cultures and selected tissues of Infected rainbow trout. The combination of PCR and nucleic acid probe promises to provide a detection method for IHNV that is rapid, h~gh ly specific, and sensltlve
