Attempts failed to infect Coturnix quail with infectious bursal disease (IBD) virus by exposure at 7, 14, 21, and 31 days old. There were no clinical signs or gross and microscopic changes in the bursa of Fabricius, and serologic tests and virus isolation attempts from cloacal swabs were negative. Turkeys of two breeds exposed to IBD virus at 6 or 8 weeks old showed no clinical signs or lesions in the bursa of Fabricius, and the virus could not be isolated from cloacal swabs. They did respond serologically, however, by developing both precipitin and virus-neutralizing antibodies.
在7日龄、14日龄、21日龄和31日龄时，尝试通过接触传染性法氏囊病（IBD）病毒来感染鹌鹑，但均告失败。法氏囊中未出现任何临床症状，肉眼及显微镜下均无变化，泄殖腔拭子的血清学检测及病毒分离尝试均为阴性。两个品种的火鸡在6周龄或8周龄时接触IBD病毒，法氏囊中未出现临床症状或病变，泄殖腔拭子中也未分离到病毒。然而，它们确实产生了血清学反应，出现了沉淀素和病毒中和抗体。
