title: Demonstration of avian influenza-A virus in Iran by immunodiffusion technique.
abstract: A total of 1000 chicken serum samples (CSS) and 235 turkey serum samples (TSS) were tested by an immunodiffusion procedure against soluble antigen (S-antigen) prepared from avian influenza-A virus (AIAV), T/Calif/5142/66. None of the CSS tested developed any precipitin line, whereas 8.9% of the TSS tested developed well-defined precipitin lines against S-antigen. This observation confirmed the presence of AIAV in Iran.
