Duck virus enteritis occurred in the spring of 1982 among domesticated mallards, Pekin ducks and geese producing eggs for the same hatchery. Wild mallards may have introduced the infection to the domestic birds. High mortality occurred in one flock of Pekin ducks and in young geese. Mallards were also affected, but less severely. Gross and microscopic lesions were in general typical for DVE. Virus was demonstrated by electron microscopy of Bursa fabricii from experimentally infected ducklings. Neutralizing antibodies were found in serum from ducks, surviving an acute outbreak in the flock. Vaccination was performed and hygienic precautions taken, and transmission from infected flocks to progeny was negligible.
1982年春季，在为同一孵化场产蛋的家养野鸭、北京鸭和鹅群中发生了鸭病毒性肠炎。野鸭可能将感染传播给了家禽。一群北京鸭和幼鹅中出现了高死亡率。野鸭也受到了影响，但程度较轻。大体和显微镜下病变总体上是鸭病毒性肠炎的典型表现。通过对实验感染雏鸭的法氏囊进行电子显微镜检查证实了病毒的存在。在鸭群急性疫情中存活下来的鸭血清中发现了中和抗体。进行了疫苗接种并采取了卫生预防措施，感染鸭群向后代的传播可以忽略不计。
