An adult cattle egret (Bubulcus ibis) caught in Kobe of Hyogo Prefecture, Japan, in December 1995 died of a severe infection associated with the trematode parasite Pegosomum sp. At necropsy, 22 trematode parasites were found in the lumen of the bile duct, and the duct wall was markedly thickened. Histopathologically, severe cholangitis and cholecystitis were observed in close association with the parasites in the bile duct. Severe Pegosomum sp. infection may be one of the factors contributing to the mortality of wild cattle egrets. This is the first reported case of the genus Pegosomum infection in wild birds of Japan.
1995年12月，在日本兵库县神户捕获的一只成年牛背鹭（牛背鹭属）死于与吸虫寄生虫佩戈吸虫属相关的严重感染。尸检时，在胆管腔内发现了22条吸虫寄生虫，胆管壁明显增厚。组织病理学检查发现，胆管内的寄生虫与严重的胆管炎和胆囊炎密切相关。严重的佩戈吸虫属感染可能是导致野生牛背鹭死亡的因素之一。这是日本野生鸟类中首次报道的佩戈吸虫属感染病例。
