The life cycle of Dioctophyma renale involves an intermediate host (oligochaete), a paratenic hosts (fish and frogs), and a definitive host (mustelids and canids). Dogs are at risk of infection with D. renale when they consume paratenic hosts infected with the larval form of D. renale. Water containing the oligochaete intermediate host cannot be disregarded as another source of infection. Infections occur mainly in the right kidney, but worms have also been found in the abdominal cavity as well as other organs. Most dogs appear asymptomatic and infections are usually noted as incidental findings on necropsy. Recently, the Ontario Society for the Prevention of Cruelty to Animals (SPCA) and Humane Society conducted transports of dogs located in northern remote communities. In 2016, some female dogs were found to be infected with D. renale upon ovariohysterectomy. In response to this discovery, we developed a screening protocol to screen for D. renale infections. In 2018, a total of 130 intact dogs were transferred from 2 northern communities in the provinces of Ontario and Manitoba. A prevalence of 7.94% (95% confidence interval 3.87–14.11%) was found from dogs from the northern communities. The screening protocol we developed provides a method of screening for dogs that are transported from communities that could be at risk of infection with D. renale.

肾脏双歧杆菌的生命周期涉及一个中间宿主（寡壳动物），一个破腹宿主（鱼和青蛙）和一个确定宿主（疣和犬科动物）。当狗食用被幼虫形式的肾小球藻感染的腹泻宿主时，它们有感染肾小球藻的风险。。含有寡糖中间体宿主的水不能被视为另一种感染源。感染主要发生在右肾，但在腹腔以及其他器官中也发现了蠕虫。大多数狗无症状，通常尸检发现感染。最近，安大略省防止虐待动物协会（SPCA）和人道协会在北部偏远社区进行了狗的运输。在2016年，发现一些雌性狗在卵巢子宫切除术后感染了D. 针对这一发现，我们开发了一种筛查方案来筛查肾小球藻。感染。2018年，从安大略省和曼尼托巴省的2个北部社区转移了总共130只完整犬。从北部社区的狗中发现患病率为7.94％（95％置信区间为3.87–14.11％）。我们开发的筛选方案提供了一种筛选从可能有感染肾小球菌的风险的社区运送的狗的方法。
