is a common coccidian found in captive bearded dragons (). To minimize the impact of this parasite, it is important to characterize its pathogenesis so that we can develop appropriate methods for diagnosis and treatment. Forty-five juvenile bearded dragons were used for this two-part study. In the first part, ten bearded dragons were infected with 20,000 oocysts per os, while a control group of five animals received only water. Feces were collected over 45 days and screened for oocysts. In the second part, thirty bearded dragons were used to characterize the pathogenesis of . Twenty-five bearded dragons were infected as described previously, while five animals served as controls. Five infected bearded dragons and one control were humanely euthanized on days 4, 8, 12, 16, and 20 post-infection for complete necropsies. The pre-patent period for was found to be 18.6 ± 1.9 days (range 15-22 days). Histopathology confirmed that follows a homoxenous life cycle. Infections begin in the duodenum and progress to the colon over time. The findings of this study can be used to develop better quarantine and treatment protocols for captive bearded dragons.
是一种在圈养鬃狮蜥中常见的球虫（）。为了尽量减少这种寄生虫的影响，了解其发病机制很重要，这样我们就能开发出合适的诊断和治疗方法。45只幼年鬃狮蜥用于这项分为两部分的研究。在第一部分中，10只鬃狮蜥经口感染20000个卵囊，而5只动物的对照组只接受水。在45天内收集粪便并筛查卵囊。在第二部分中，30只鬃狮蜥用于研究的发病机制。25只鬃狮蜥按先前描述的方法感染，5只动物作为对照。在感染后第4、8、12、16和20天，对5只感染的鬃狮蜥和1只对照进行安乐死以进行完整的尸检。的潜伏期为18.6±1.9天（范围15 - 22天）。组织病理学证实遵循同种生活周期。感染始于十二指肠，随着时间的推移发展至结肠。本研究的结果可用于为圈养鬃狮蜥制定更好的检疫和治疗方案。
