[Attempts to demonstrate and identify avian adenoviruses by an immunofluorescence method].

A specific conjugate of a hyperimmune serum, obtained from rabbits with the use of the reference Phelps-CELO strain, was employed in a direct immunofluorescence method to investigate more than 320 lamelles with cell cultures infected with 4 field CELO virus strains and the reference Phelps-CELO strain.
