狗自古以来就被饲养用于陪伴，狩猎，保护，牧羊和其他人类活动。一些犬蠕虫寄生虫可引起人类重大临床疾病，如在东南亚国家引起胆管癌的猫尾后睾吸虫。在这项研究中，社会文化问卷调查，犬寄生虫学分析，尸检，寄生虫分子确认和狗漫游数据进行了评估，在沙湾拿吉，老挝人民民主共和国，一个典型的湄公河流域地区。狗主人占研究人群的48.8%，其中61.2%拥有一只狗，25.1%拥有2只狗，8.5%拥有3只狗，1.8%拥有4只以上狗。从狗身上的GPS记录器获得的数据显示，它们每天行走1.4至13.3公里，平均占地3356.38平方米，并定期获取水源。观察到13种人畜共患蠕虫。幼虫内脏移行症和皮肤移行症的病原分别占44.1%和70%。在44.1%的样品中检测到刺猬迭宫绦虫。重要的是，O。在8.8%的样本中发现了灵猫病毒。除了已知的狗在传播钩虫属物种中的重要性外，弓蛔虫属和S. erinaceieuropaei，观察到的狗的漫游模式证实了它是一个重要的主机永存O。灵猫在流行地区;他们的日常访问水体可能会传播O。灵猫卵在有利于吸虫发育的环境中产卵，促进鱼类感染，从而感染生活在同一生态系统中的人类。因此，在湄公河流域地区，人体寄生虫NTDs控制计划应与动物寄生虫控制平行进行，特别是狗。
Dogs have been bred since ancient times for companionship, hunting, protection, shepherding and other human activities. Some canine helminth parasites can cause significant clinical diseases in humans as Opisthorchis viverrini causing cholangiocarcinoma in Southeast Asian Countries. In this study, socio-cultural questionnaire, canine parasitological analysis, necropsy, parasite molecular confirmation and dog roaming data were evaluated in Savannakhet, Lao-PDR, a typical Mekong Basin area. Dog owners comprised 48.8% of the studied population, with 61.2% owning one dog, 25.1% 2 dogs, 8.5% 3 dogs and 1.8% owning more than 4 dogs. Data from GPS logger attached to dogs showed they walked from 1.4 to 13.3 km per day, covering an area of 3356.38m2 average, with a routine of accessing water sources. Thirteen zoonotic helminth species were observed. Causative agents of visceral and cutaneous larva migrans occurred in 44.1% and 70% of the samples respectively. Spirometra erinaceieuropaei was detected in 44.1% of samples. Importantly, O. viverrini was found in 8.8% of samples. Besides the known importance of dogs in the transmission of Ancylostoma spp., Toxocara spp. and S. erinaceieuropaei, the observed roaming pattern of dogs confirmed it as an important host perpetuating O. viverrini in endemic areas; their routine access to waterbodies may spread O. viverrini eggs in a favorable environment for the fluke development, facilitating the infection of fishes, and consequently infecting humans living in the same ecosystem. Therefore, parasitic NTDs control programs in humans should be done in parallel with parasite control in animals, especially dogs, in the Mekong River basin area.
