PG - 567-71 AB - Polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) analysis was developed for directly typing porcine reproductive and respiratory syndrome virus (PRRSV) from lung specimens without virus isolation. Twenty nine lung specimens collected from postweaning pigs were isolated for PRRSV. When the PCR products from the 29 lung specimens were digested by the restriction enzymes MluI, HincII, SacII and HaeIII, the RFLP patterns from the 29 lung specimens matched with those from the corresponding PRRSV isolates from each pig. The results suggest that the PCR-based RFLP analysis method may be useful to distinguish PRRSV isolates directly from lung specimens without virus isolation.
