Between January 1975 and August 1976, the alimentary tracts of 104 euthanatized dogs from a humane shelter in Tippecanoe County, Indiana, were examined to determine the prevalence of gastrointestinal helminths. The survey was restricted to dogs greater than 1 year old. Their average age was estimated at approximately 2 years. Parasitism was detected in 86.5% of the dogs examined. Ancylostoma caninum was found most often (58.7%), followed by Trichuris vulpis (51.9%), Taenia sp (31.7%), Toxocara canis (18.3%), Dipylidium caninum (16.3%), Toxascaris leonina (8.7%), and Physaloptera rara (3.8%). Monospecific infections were found in 22.1% of the dogs, whereas concurrent infections with 2 or more species were found in 64.4% of the dogs. Most commonly encountered were dogs infected with 2 species of parasites (39.4%), of which hookworms plus whipworms were found most often (32.7%). Male dogs had a higher percentage of multiple infections than did female dogs.
1975年1月至1976年8月期间，对来自印第安纳州蒂珀卡努县一家人道收容所的104只实施安乐死的犬类的消化道进行了检查，以确定胃肠道蠕虫的感染率。该调查仅限于1岁以上的犬类。它们的平均年龄估计约为2岁。在接受检查的犬类中，86.5%检测到寄生虫感染。犬钩虫最为常见（58.7%），其次是狐毛首线虫（51.9%）、带绦虫属（31.7%）、犬弓首蛔虫（18.3%）、犬复孔绦虫（16.3%）、狮弓蛔虫（8.7%）和罕见泡翼线虫（3.8%）。22.1%的犬类为单一感染，而64.4%的犬类同时感染了两种或更多种寄生虫。最常见的是感染两种寄生虫的犬类（39.4%），其中钩虫和鞭虫同时感染最为常见（32.7%）。雄性犬类多重感染的比例高于雌性犬类。
