Abstract：
Raccoon roundworm, Baylisascaris procyonis, is a zoonotic parasite of raccoons (Procyon lotor) that needs a One Health approach to better inform risks to human and animal health. The few studies on B. procyonis in wild rodents have primarily focused on white-footed mice (Peromyscus leucopus). This study aimed to determine the prevalence and rodent host range of B. procyonis in Georgia (USA) and investigate differences in prevalence at urban/fragmented sites and rural/agriculture sites. We sampled 99 rodents of five species. Larvae were recovered from seven of 78 (9.0%) white-footed mice with a mean of 4.4 larvae (range 1-12). One mouse had a single larva in the brain. Prevalence was not different between urban and rural sites. This report extends the geographic range of this parasite and confirms that rodents serve as paratenic hosts in the southern range. Therefore, baylisascariasis should be considered a differential for neurologic domestic animals, wildlife, or people in this region.
摘要：
浣熊蛔虫,BaylisascarisProcyonis,是浣熊（Procyonlotor）的人畜共患寄生虫，需要一个健康的方法来更好地告知人类和动物健康的风险。关于野生啮齿动物中的B.procyonis的少数研究主要集中在白足小鼠（Peromescusleucopus）上。这项研究旨在确定佐治亚州（美国）的B.procyonis的患病率和啮齿动物宿主范围，并调查城市/分散地点和农村/农业地点的患病率差异。我们采样了5种的99只啮齿动物。从78只白足小鼠中的7只（9.0％）中回收幼虫，平均有4.4只幼虫（范围1-12）。一只老鼠的大脑中有一只幼虫。城市和农村地区的患病率没有差异。该报告扩展了该寄生虫的地理范围，并证实了啮齿动物在南部范围内充当了寄生虫宿主。因此,Baylisas虫病应被认为是神经家养动物的差异，野生动物,或者这个地区的人。
