SUMMARY Bursae from chickens infected with infectious bursal disease have been examined by immune electron microscopy. Two types of virus particle have been detected, the larger being 55 to 60 nm in diam. and markedly hexagonal in outline, while the smaller has an appearance similar to that of the parvoviruses with a diam. of 18 to 22 nm. The presence of mixed aggregates and demonstrable antibody-bridging show that the two types of particle have at least one surface antigen in common.
