InactiveCN105543415AOvercoming serious flawsMicrobiological testing/measurementDNA/RNA fragmentationHerpes simplex virus DNAPcr method
The invention provides a nest type PCR method for detecting different variants of an ostreid herpes virus-1 (OsHV-1). According to the detection method, an ostreid herpes virus DNA polymerase gene functional domain nucleotide sequence is adopted as a template, two pairs of nested primers are designed, and the nest type PCR detection method is designed based on the theme. Due to the fact that DNA polymerase genes are highly conservative on a herpes virus intraspecific category, the two pairs of nested primers can be combined with all currently-known OsHV-1 variant genomes, specific DNA nucleic acid fragments of the variants are qualitatively detected, and high sensitivity and good specificity are achieved. The severe defect that an existing molecular detection method can only detect part of the variants of the OsHV-1 can be overcome through the detection method. The detection method can be used for tracking and detection on the ostreid herpes virus during breeding of shells in all periods, and has high use value.
