Giardia cysts were detected in feces of a domestic llama (Lama glama) and in feces of lambs (Ovis aries) from Wisconsin, U.S.A. All of the animals examined were immature, and they had recent histories of poor condition and passing unformed or semiformed, pale stools. Giardia cysts from both host species were excysted in vitro, and the trophozoites were cultivated axenically. Furthermore, Giardia cysts from both sources were shown to produce infection in Mongolian gerbils (Meriones unquiculatus). The finding of Giardia in the llama represents a new host recorded for this parasite. Also, this is the first report of Giardia-infected sheep from the Western Hemisphere.
在美国威斯康星州的一只家养美洲驼（小羊驼）粪便以及羔羊（绵羊）粪便中检测到了贾第虫包囊。所有接受检查的动物均未成熟，且近期身体状况不佳，排出不成形或半成形的浅色粪便。来自这两种宿主物种的贾第虫包囊在体外脱囊，滋养体进行了无菌培养。此外，来自这两个来源的贾第虫包囊均在蒙古沙鼠（长爪沙鼠）中引发了感染。在美洲驼中发现贾第虫代表了该寄生虫的一个新宿主记录。而且，这是西半球关于感染贾第虫绵羊的首次报道。
