claim: microwave or autoclave cannot destroy the infectivity of infectious bronchitis virus and avian pneumovirus but allow detection by reverse transcriptase-polymerase chain reaction
evidence_1: autoclaving and microwave treatment for as little as 20 sec destroyed the infectivity of all four viruses.", "microwave treatment appears to be a satisfactory method of inactivating virus while preserving nucleic acid for pcr identification.", "however, both ibv and apv could be detected by reverse transcriptase (rt)-pcr after autoclaving and as long as 5 min microwave treatment (newcastle disease virus and avian influenza viruses were not tested).")
