人们发现，一种通常自由生活的膜口纤毛虫是纽约水族馆饲养的大西洋和太平洋海洋鱼类的鳃、内脏和身体肌肉严重感染的原因。特别令人感兴趣的是，寄生虫通常带有充满血细胞和细胞碎片的食物泡，对身体肌肉造成了广泛的损害。其他受感染的器官没有表现出特征性的组织反应。死亡的直接原因是鳃上寄生虫的异常负荷，从而干扰了正常的呼吸功能。从最近的一次爆发中分离出的纤毛虫被详细描述，并显示出Uronema marinum Dujardin的许多特征，据报道，该物种在盐水中自由生活；这里报告的形式与该物种中包含的类型和其他成员不同，因为存在少于三排双极经络。详细描述了这种兼性寄生虫并与其他属进行了比较。
A normally free‐living hymenostomatid ciliate was found to be the cause of heavy infections of gills, viscera and body muscle in Atlantic and Pacific marine fishes kept in the New York Aquarium. Of special interest is the fact that the parasites, usually with food vacuoles filled with blood cells and cellular debris, caused extensive damage to the body muscle; the other infected organs showed no characteristic tissue reactions. The immediate cause of death is attributed to the exceptional load of the parasite on the gills, thus interfering with normal respiratory function.The ciliate, isolated from a recent outbreak, is described in detail, and shows many characteristics ofUronema marinumDujardin, a species that has been reported as free‐living in salt water; the form reported here differs from the type and other members included in this species, by the presence of less than three rows of bipolar meridians. This facultative parasite is described in detail and compared with other genera.
