Abstract | Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most challenging infectious disease of pig populations causing devastating economic loss to swine industry. Reverse genetics allow to engineer modified viruses such attenuated strains for vaccine development. Some reverse genetic systems were described for PRRSVs but, due to genome complexity of PRRSVs, construction and modification of such systems remain laborious and time-consuming.In this study, we described a reverse genetics approach based on the “Infectious-Subgenomic Amplicons” (ISA) method to rescue infectious PRRSV particles. Permissive cells were transfected with 4 overlapping synthetic DNA fragments covering the entire genome of PRRSV which allowed the rapid reconstruction of the complete virus genome and the subsequent generation of infectious wild-type particles within days.The ISA method represent a rapid alternative of conventional reverse genetic systems. This method will help to generate genetically modified and attenuated strains for the development of sanitary countermeasures in the future. |
