The species, including are tapeworms that primarily infect canids such as dogs, foxes and coyotes, but which can also infect humans. In humans, can cause alveolar echinococcosis; a serious condition that mimics metastatic malignancy and has a poor prognosis. It is known that coyotes in rural Manitoba are infected with species, but it is not known if coyotes in peri-urban areas are also infected.
To document and map species in wild canids and domestic dogs in Winnipeg, Manitoba (Canada).
There were 169 fecal samples collected between April 18 and June 1, 2018. These included 44 samples of domestic dog feces, 122 of coyote scat, one of fox scat and two of coyote colonic tissue specimens. Samples were frozen (-80°C) for at least 72 hours to inactivate tapeworm ova. Polymerase chain reaction analyses of were performed on all frozen samples.
positive samples were detected in nine (10.6%) of 85 locations, with one positive sample in a suburban Winnipeg dog park and two positive samples in a popular provincial park. No dog samples were positive for one sample was positive for . In contrast, nine coyote samples (7.3%) were positive for and eight samples (6.5%) were positive for The one fox sample was positive for each. Overall, six samples (3.6%) were positive for both infections.
This is the first confirmation of the presence of in coyote feces in the metropolitan area of Winnipeg, Manitoba. In light of the risk this could pose to domestic dogs and human health, periodic surveillance that maps the distribution of this tapeworm could inform the need for additional public health actions.
该物种，包括 ，是主要感染犬科动物（如狗、狐狸和郊狼）的绦虫，但也可感染人类。在人类中， 可导致泡型包虫病；这是一种严重疾病，类似转移性恶性肿瘤，预后不良。已知马尼托巴农村地区的郊狼感染了 物种，但尚不清楚城市周边地区的郊狼是否也受到感染。
记录并绘制加拿大马尼托巴省温尼伯市野生犬科动物和家犬体内 物种的分布情况。
2018年4月18日至6月1日期间收集了169份粪便样本。其中包括44份家犬粪便样本、122份郊狼粪便样本、1份狐狸粪便样本和2份郊狼结肠组织标本。样本在-80°C下冷冻至少72小时以使绦虫卵失活。对所有冷冻样本进行 聚合酶链反应分析。
在85个地点中的9个（10.6%）检测到阳性样本，其中温尼伯市郊区的一个狗公园有1份阳性样本，一个受欢迎的省级公园有2份阳性样本。没有家犬样本检测出 呈阳性，1份样本检测出 呈阳性。相比之下，9份郊狼样本（7.3%）检测出 呈阳性，8份样本（6.5%）检测出 呈阳性。狐狸样本检测出这两种均呈阳性。总体而言，6份样本（3.6%）两种感染均呈阳性。
这是首次证实加拿大马尼托巴省温尼伯市都会区郊狼粪便中存在 。鉴于这可能对家犬和人类健康构成风险，定期监测该绦虫的分布情况可为采取更多公共卫生行动提供依据。
