Detection and serological identification of adeno-associated virus in avian adenovirus stocks

Eleven avian adenovirus strains were tested for the presence of avian adeno-associated viruses (AAAV). Six strains contained AAAV. Electron microscopy using rabbit anti-AAAV serum was useful in detecting the satellite virus. The AAAV previously isolated from guail bronchitis virus was related to each of the six new isolates by immunoagglutination, complement fixation, immunodiffusion, and neutralization tests.
