Raccoon latrines represent sites of potential infection by the zoonotic parasite Baylisascaris procyonis for wildlife and humans. Our objective was to determine the prevalence of B. procyonis at raccoon latrine sites in southern Ontario. Thirty raccoon latrines were sampled between June - July 2018; multiple scats were collected and homogenized to form a representative sample of each latrine. To determine the presence or absence of B. procyonis eggs in each sample, we used the Cornell-Wisconsin centrifugal floatation technique. Twenty-three percent (7/30) of homogenized samples tested positive for B. procyonis. Eggs per gram of feces ranged from 1 to 388 (median = 1.28, IQR = 0.32-232.5). Baylisascaris procyonis positive latrines were found in conservation areas heavily used by people, which may represent a possible source of exposure for humans in these areas.
浣熊的粪便堆是潜在的感染源，携带的寄生虫可以感染野生动物和人类，其中包括蛲虫。我们的目的是确定在安大略省南部浣熊粪便堆处蛲虫的流行程度。2018 年 6 月至 7 月期间，我们对 30 个浣熊粪便堆进行了采样；收集了多个粪便并将其混合均匀，形成每个粪便堆的代表性样本。为了确定每个样本中是否存在蛲虫卵，我们使用了康奈尔-威斯康星离心漂浮技术。23%（7/30）的混合样本检测出蛲虫阳性。每克粪便中的虫卵数从 1 到 388 不等（中位数=1.28，IQR=0.32-232.5）。在人类频繁使用的保护区中发现了蛲虫阳性的粪便堆，这可能代表了这些地区人类暴露的潜在来源。
