The papers in this section represent the proceedings of the Symposium, “Current Advances in Avian Immunology” held preceding the 1993 Poultry Science Association Meeting. The symposium papers are initiated by contributions from two keynote immunologists, Noel Rose and Bruce Glick. Subsequent contributions follow a progression in which current concepts regarding avian immune mechanisms are first detailed by immune cell type. This is followed by consideration of interactions between the avian immune system and other genetic or physiological factors, including the soluble mediators for these interactions. Finally, a discussion of immune-environment interactions leads into presentations describing current and future strategies for immune management of poultry.
