Lack of in vitro cultivation methods has inhibited the development of rapid, reliable diagnostic procedures for adenovirus-associated necrotizing bronchopneumonia in guinea pigs. Because polymerase chain reaction (PCR) techniques are well established for human adenoviruses, primers for the amplification of guinea pig adenovirus DNA were evaluated. The DNA for PCR was purified from the lung tissue of spontaneously infected and healthy guinea pigs. Adenovirus DNA could only be detected in the lungs of the infected animals. Subsequent sequence analysis of PCR products revealed that the guinea pig adenovirus is a distinct adenovirus.
