Use of polymerase chain reaction to detect latent channel catfish virus
1991
Boyle, J. | Blackwell, J.
Polymerase chain reaction was used to detect an economically important herpesvirus, channel catfish virus (CCV). A segment of the viral DNA was sequenced and oligonucleotide primers were produced from that sequence. After the primers were tested for the possibility of hybridization to catfish DNA, they were used to prime the polymerase chain reaction, using pure CCV DNA, CCV DNA added to catfish DNA, and DNA from catfish infected and not infected with CCV. In all cases, the method proved to be simple and sensitive in its detection of CCV DNA. When catfish DNA was present, < 0.1 pg of CCV DNA was detectable. Channel catfish virus DNA in a latent carrier of CCV was readily detectable.
