Surveillance of Echinococcus multilocularis infection among 156 shelter dogs was conducted in an urban area (Sapporo city) in Hokkaido, where the parasite is endemic in Japan using copro-DNA and fecal egg examination from September 2013 to April 2017. Echinococcus infection was detected in three dogs (1.9%), including one dog that excreted eggs. The results suggested that free-roaming or stray dogs in urban area may be infected by capturing wild voles containing parasitic cysts and could be a source of human infection. Dog-to-human transmission is a significant concern, and the risk of such transmission is present even in urban areas in Hokkaido. We recommend deworming within 1 month (e.g., before egg excretion) of capture for free-roaming or stray dogs in Echinococcus-endemic area to prevent potential human infection.
2013年9月至2017年4月，在日本北海道的一个城市地区（札幌市），对156只庇护犬进行了多房棘球绦虫感染监测，该寄生虫在日本为地方病流行区，采用粪便DNA检测和粪便虫卵检查。在三只犬（1.9%）中检测到棘球绦虫感染，其中一只犬排出了虫卵。结果表明，城市地区的流浪犬或散养犬可能因捕食含有寄生囊肿的野生田鼠而感染，并且可能成为人类感染源。犬向人的传播是一个重大问题，即使在北海道的城市地区也存在这种传播风险。我们建议，对于棘球绦虫流行地区的流浪犬或散养犬，在捕获后1个月内（例如在排出虫卵之前）进行驱虫，以预防潜在的人类感染。
