WebbIn attempts to gain insights into the mechanism of PRRSV persistence in boars, tissue distribution and sites of viral infection were investigated by in situ hybridization (ISH) using digoxigenin-labeled RNA probe and the ISH results were compared with those of reverse transcription-nested polymerase chain reaction (RT-nested PCR).

WebbAt the final stage of infection, PRRSV replication gradually declines until the virus becomes eliminated in the host. However, the virus may persist in pigs for a longer period of time. The mechanism of persistence may be based on the high mutation rate of the PRRSV RNA genome allowing an escape from the host immune surveillance.
