2001年，神奈川县一家水族馆的杂草海龙被发现感染了原生动物纤毛虫。特别是受感染的鱼，表现出表皮脱落。严重感染的鱼表现为背鳍脱落、皮肤色素脱失、肛门扩张和腹腔积液。在活组织检查中，仅在新鲜的腹部水肿和体表粘液中检测到纤毛虫。组织学研究表明，纤毛虫主要感染真皮，并引起广泛的表皮从皮肤上脱落。根据口部结构的排列和形状以及体纤毛的数量，从鱼类中分离出的纤毛虫属于盾纤毛虫目（Scuticociliatida）。我们讨论了导致杂草海龙死亡的主要因素。
The weedy sea dragon Phyllopteryx taeniolatus at an aquarium in Kanagawa Prefecture were found infected by protozoan ciliate, 2001. The infected fish in particular, showed sloughing of the epidermis. Fish with intense infections showed sloughing of the dorsal fin, depigmentation of skin, anal distension and accumulation of ascitic fluid in the body cavity. In biopsies, ciliates were detected only in fresh mounts of abdominal dropsy and in the mucus on the body surface. Histopathological studies revealed ciliates mainly infected the dermis, and induced extensive detachment of the epidermis from the skin. Based on the arrangement and shape of the buccal structure and the number of somatic ciliature, ciliates isolated from the fishes belonged to the order Scuticociliatida. We discuss the major factors that bring about the death of weedy sea dragons.
