Coyotes from southern Alberta and Saskatchewan, Canada, were examined for the presence of Giardia and Cryptosporidium and cohabiting helminths. Toxascaris was present in over 90% of the 70 animals examined, and Taenia sp. in 6.5-25% of the two groups of animals studied. Giardia (12.5-21.7%) and Cryptosporidium (0-17.4%) were also common and molecular characterisation revealed both zoonotic and host-adapted genotypes of Giardia, whereas the Cryptosporidium proved to be a variant of the canine species C. canis. The seasonal variation observed in the occurrence of Cryptosporidium may be related to stress-induced shedding of the parasite.
对来自加拿大艾伯塔省南部和萨斯喀彻温省的郊狼进行了检查，以确定是否存在贾第虫、隐孢子虫和共生蠕虫。在所检查的70只动物中，超过90%感染了弓首蛔虫，在两组研究动物中，6.5%-25%感染了带绦虫属。贾第虫（12.5%-21.7%）和隐孢子虫（0%-17.4%）也很常见，分子特征显示贾第虫存在人畜共患型和宿主适应型基因型，而隐孢子虫被证明是犬种犬隐孢子虫的一个变种。观察到的隐孢子虫感染发生率的季节性变化可能与应激诱导的寄生虫脱落有关。
