In a Muscovy duck breeding-growing farm in Aomori prefecture, most of ducklings hatched during spring in 1994 died within two-week-old. The mortality was nearly 100%. In most cases, birds died without clinical signs and some with leg weakness. By serological and virological tests, the outbreak was identified as a goose parvovirus infection. In pathological test, however, no typical manifestations of goose parvovirus infections (hepatitis and intranuclear inclusion bodies in hepatic cells) were detected.
在青森县的一个番鸭养殖农场，1994年春季孵化的大多数雏鸭在两周龄内死亡。死亡率几乎为100%。大多数情况下，雏鸭无临床症状死亡，部分雏鸭腿部无力。通过血清学和病毒学检测，此次疫情被确认为鹅细小病毒感染。然而，在病理检测中，未检测到鹅细小病毒感染的典型表现（肝炎及肝细胞内的核内包涵体）。
