title: Report of IABS committee on avian product standardization.
abstract: The International Association of Biological Standardization (IABS) organized an international symposium in August 1973 on the "Requirements for Poultry Virus Vaccines" at Lyon (France). The Proceedings of this symposium were subsequently published as "Developments in Biological Standardization", volume 25. At the conclusion of this symposium, it was resolved that an Avian Biological Products Standardization Committee should be established, this committee including four subcommittees, each under the direction of a chairman who would be responsible to make a report on his own subject. The four subjects are: specific pathogen freedom (SPF), infectious bronchitis, Marek's disease, Newcastle disease. The work established by the Committee is presented.
