Canine soil-transmitted helminth (cSTH) parasites need specific environmental conditions to complete their life cycle. and are the most important zoonotic cSTH, since they are the causal agents of human toxocariasis. Canine STHs are dispersed in feces from infected domestic and wildlife canines. In this study, the presence of STH in canine feces was evaluated in 34 crowded public parks and squares from San Juan Province (Argentina).
Fecal samples were collected during different seasons in 2021-2022 and analyzed by standard coprological methods, including Sheather and Willis flotation and Telemann sedimentation. InfoStat 2020, OpenEpi V. 3.01 and R and RStudio® were used for statistical analysis and QGIS 3.16.10 for mapping.
From a total of 1,121 samples collected, 100 (8.9%) were positive for at least one intestinal parasite (IP) and three cSTH species were detected: spp., and . The most prevalent cSTH species was (64/1121; 0.057%), while the least prevalent was spp. (19/1121; 0.017%). The detection of spp. eggs was significantly different depending on the season. The geo-spatial variation of each cSTH per season is described.
This is the first study in San Juan Province to identify environmental contamination of cSTHs in public areas. The specific localization of areas with the presence of cSTH eggs could provide information to guide strategies to reduce the cSTH infection burden in dogs and promote serological screening of the human population for spp. Given the zoonotic nature of spp. We hope this information will help to reinforce activities of control programs, focusing on the "One Health" approach.
犬类土壤传播蠕虫（cSTH）寄生虫需要特定的环境条件来完成其生命周期。 和 是最重要的人兽共患cSTH，因为它们是人类弓蛔虫病的病原体。犬类STH通过受感染的家养和野生动物犬类的粪便传播。在本研究中，对阿根廷圣胡安省34个拥挤的公园和广场中犬类粪便中的STH存在情况进行了评估。
在2021 - 2022年的不同季节收集粪便样本，并通过标准粪便学方法进行分析，包括谢弗和威利斯浮选法以及泰勒曼沉淀法。使用InfoStat 2020、OpenEpi V. 3.01以及R和RStudio®进行统计分析，使用QGIS 3.16.10进行绘图。
在总共收集的1121份样本中，100份（8.9%）至少对一种肠道寄生虫（IP）呈阳性，检测到三种cSTH物种： 属、 和 。最常见的cSTH物种是 （64/1121；0.057%），而最不常见的是 属（19/1121；0.017%）。 属虫卵的检测在不同季节有显著差异。描述了每个季节每种cSTH的地理空间变化。
这是圣胡安省首次在公共区域识别cSTH环境污染的研究。存在cSTH虫卵区域的具体定位可为指导降低犬类cSTH感染负担的策略以及促进对人群进行 属血清学筛查提供信息。鉴于 属的人兽共患性质，我们希望这些信息将有助于加强控制项目的活动，重点是“同一健康”方法。
