The first records of 3 helminth parasites from otters, Lutra canadensis, collected in Tennessee are reported. Digestive tracts of 91 river otters collected from 1983 to 1993 were examined for helminth parasites. Thirty otters were infected with Baschkirovitrema incrassatum, 5 otters were infected with Acanthocephalus sp., and 1 otter was infected with 2 Strongyloides lutrae. No significant differences in prevalence, mean abundance, or mean intensity of B. incrassatum occurred between counties or months. No significant differences in the prevalence or mean intensity of B. incrassatum occurred between years, but significant yearly differences in mean abundance were recorded from 1988 through 1993 (P < 0.05). There were no statistical differences in B. incrassatum parasitization between males and females or juvenile and adult otters.
报告了在田纳西州收集的北美水獭（Lutra canadensis）体内3种蠕虫寄生虫的首次记录。对1983年至1993年收集的91只水獭的消化道进行了蠕虫寄生虫检查。30只水獭感染了增厚巴氏吸虫（Baschkirovitrema incrassatum），5只水獭感染了棘头虫属（Acanthocephalus sp.），1只水獭感染了2种水獭类圆线虫（Strongyloides lutrae）。增厚巴氏吸虫的感染率、平均丰度或平均强度在不同县或月份之间没有显著差异。增厚巴氏吸虫的感染率或平均强度在不同年份之间没有显著差异，但1988年至1993年记录到平均丰度存在显著的年度差异（P < 0.05）。增厚巴氏吸虫在雄性和雌性水獭或幼年和成年水獭之间的寄生情况没有统计学差异。
