Rapid identification of "very virulent" strains of infectious bursal disease virus by reverse transcription-polymerase chain reaction combined with restriction enzyme analysis

Abstract excerpt

A reverse transcription-polymerase chain reaction (RT-PCR) combined with restriction enzyme analysis (REA) was developed for differentiation of classical virulent (cv) and very virulent (vv) strains of infectious bursal disease virus (IBDV). The VP2 gene was used for primer annealing to amplify the hypervariable region. An amplification product was obtained with serotype 1 and serotype 2 strains of IBDV.The...
