为明确自然气候对犬肠道寄生虫感染率的影响，对2093只家犬进行了为期15个月的粪便漂浮法检查。在密苏里州的伦纳德伍德堡[美国]。15个气候变量进行了比较的频率寄生。球虫（等孢球虫属）自然单次和多次感染的频率，蛔虫（犬弓蛔虫和狮弓蛔虫）、钩虫（犬钩虫）和鞭虫（狐鞭虫）被确定并用于评估多重感染的随机性。在比较寄生与气候因素，一个复杂的生物气候关系，发现这种关系是依赖于寄生剂（S）和相对的时间框架。自然气候条件影响犬钩虫感染率。一个生物气候相互作用，涉及犬主机和寄生虫的额外主机的生命阶段的建议。
In an effort to define the effects of the natural climate on the infection rates of canine alimentary parasites, a fecal flotation examination for alimentary parasites was performed on 2093 domestic dogs during a 15 mo. period at Fort Leonard Wood, Missouri[USA]. Fifteen climatic variables were compared with the frequency of parasitism. The frequency of natural mono- and multi-infections with coccidia (Isospora spp.), ascarids (Toxocara canis and Toxascaris leonina), hookworms (Ancylostoma caninum), and whipworms (Trichuris vulpis) was determined and used to evaluate the randomness of multi-infections. In comparing parasitisms with the climatic factors, a complex bioclimatic relationship was found. The relationship was dependent on the parasitic agent(s) and the relative time frame. Natural climatic conditions influenced the infection rate of Ancylostoma caninum. A bioclimatic interaction involving both the canine host and the parasite''s extra-host life stages is suggested.
