populations are diminishing throughout their range due to urbanization, fragmentation, and poor habitat management. Increased population densities, poor habitat quality, and lack of fire may influence disease transmission. Parasite roles within wild tortoise populations are largely unknown; despite evidence these pathogens may pose significant health risks. This study provides a baseline of gopher tortoise intestinal parasites across South Florida and reports on how varying environmental and tortoise characteristics may affect intestinal parasite species prevalence and approximate loads. Tortoise fecal samples were taken from six tortoise populations across five South Florida sites. Seven species of intestinal parasites were discovered from 123 tortoises. Identified parasites include endohelminths such as cyathostomes, pinworms, ascarids, flukes, and protozoans including , , and species. Significant differences in parasite prevalence and loads were seen between sites, while parasitism among sex, size class, and habitat type remained relatively ubiquitous.
由于城市化、栖息地破碎化和不良的栖息地管理,其分布范围内的种群数量正在减少。种群密度增加、栖息地质量差以及缺乏火灾可能会影响疾病传播。野生陆龟种群中寄生虫的作用在很大程度上尚不清楚;尽管有证据表明这些病原体可能构成重大健康风险。本研究提供了南佛罗里达州地鼠陆龟肠道寄生虫的基线,并报告了不同的环境和陆龟特征如何可能影响肠道寄生虫物种的流行率和大致负荷。从南佛罗里达州五个地点的六个陆龟种群中采集了陆龟粪便样本。从123只陆龟中发现了七种肠道寄生虫。鉴定出的寄生虫包括内寄生虫,如杯口线虫、蛲虫、蛔虫(如:异尖线虫)、吸虫,以及原生动物,包括、和物种。不同地点之间寄生虫的流行率和负荷存在显著差异,而性别、体型类别和栖息地类型之间的寄生现象相对普遍。
