A total of 933 mottled sculpins, Cottus bairdi Girard (Cottidae), was examined for Rhabdochona cotti from April 1983 through November 1986 from 3 localities (up-river, middle, down-river) in the Ford River in Michigan's Upper Peninsula. The prevalence and mean intensity of R. cotti were highest in sculpins from the middle (37%) and up-river localities (2.0), respectively. The intensity of R. cotti significantly increased with host length at the middle and down-river localities. Rhabdochona cotti did not exhibit consistent seasonal infection patterns at each location when the data were analyzed seasonally within and between years. Gravid R. cotti infected sculpins in most seasons of each year at the up-river and middle localities. The limited occurrence of R. cotti in sculpins in North America is summarized and discussed.
1983年4月至1986年11月期间，从密歇根州上半岛福特河的3个地点（上游、中游、下游）共检查了933条斑驳杜父鱼（Cottus bairdi Girard，杜父鱼科），以检测是否感染科氏斜睾吸虫（Rhabdochona cotti）。科氏斜睾吸虫的感染率和平均感染强度在中游（37%）和上游地点（2.0）的杜父鱼中分别最高。在中游和下游地点，科氏斜睾吸虫的感染强度随宿主长度显著增加。当按年份内和年份间的季节分析数据时，科氏斜睾吸虫在每个地点并未表现出一致的季节性感染模式。在每年的大多数季节，在上游和中游地点，怀有虫卵的科氏斜睾吸虫都会感染杜父鱼。本文总结并讨论了科氏斜睾吸虫在北美杜父鱼中感染情况有限的现象。
