Analysis of ORF 1 in European porcine reproductive and respiratory syndrome virus by long RT-PCR and restriction fragment length polymorphism (RFLP) analysis
Publication: Research - peer-review › Journal article – Annual report year: 2000
A rapid method was developed for partial characterization of the replicase-encoding open reading frame 1 (ORF 1) of porcine reproductive and respiratory syndrome virus (PRRSV). It comprised long RT-PCR amplification of 11.1 kb (94%) of ORF 1, followed by restriction fragment length polymorphism analysis. The method was used to compare ORF 1 sequences of two divergent European-type PRRSV strains. Our results indicated that the structural and replicase parts of these two strains had evolved at overall similar rates.
