棘球蚴病是一种人畜共患寄生虫病，是我国青海省的高度地方病。关于致病病原体棘球绦虫属的流行率的数据有限，在这个地区的最终宿主中。因此，本研究的目的是评估棘球绦虫属的患病率。在青海省的野生狐狸和流浪狗身上。从果洛、玉树、海西等地的11个县采集野狐粪便528份和流浪犬粪便277份，进行棘球绦虫病的筛查。使用copro-DNA聚合酶链反应（PCR）。总共有5.5%的野生狐狸和15.2%的流浪狗检测出棘球绦虫属阳性。棘球蚴感染率为100%。果洛、玉树和海西野生狐的感染率分别为7.3%、5.2%和1.9%。在流浪犬中，这些比率分别为13.3%、17.3%和0%。测序分析表明，多房棘球绦虫是最常见的物种，分别在4.0%和12.6%的野生狐狸和流浪狗，发生。在野狐和流浪犬中分别检出1.5%和0.7%的志贺氏棘球绦虫。细粒棘球绦虫仅见于野狗，患病率为1.8%。据我们所知，这是第一份关于E.青海省犬中的志贺氏菌。目前的结果提高了我们对人类包虫病传播和扩散的认识，并提示暴露于E。青海省野生狐狸和流浪狗所携带的泡球蚴对人类具有很大的危险性。
Echinococcosis is a zoonotic parasitic disease that is highly endemic to the Qinghai province of China. Limited data are available on the prevalence of the causal pathogen, Echinococcus spp., in definitive hosts in this region. Thus, the aim of this study was to evaluate the prevalence of Echinococcus spp. in wild foxes and stray dogs in Qinghai province. Five hundred and twenty-eight feces from wild foxes and 277 from stray dogs were collected from 11 counties in the Golog, Yushu, and Haixi prefectures and screened for Echinococcus spp. using copro-DNA polymerase chain reaction (PCR). In total, 5.5% of wild foxes and 15.2% of stray dogs tested positive for Echinococcus spp. The prevalence rates of Echinococcus spp. in wild foxes in Golog, Yushu, and Haixi were 7.3%, 5.2%, and 1.9%, respectively. In stray dogs, these rates were 13.3%, 17.3%, and 0%, respectively. Sequencing analysis determined that Echinococcus multilocularis was the most prevalent species, occurring in 4.0% and 12.6% of wild foxes and stray dogs, respectively. Echinococcus shiquicus was observed in 1.5% of wild foxes and 0.7% of stray dogs. Echinococcus granulosus was observed only in wild dogs, with a prevalence rate of 1.8%. To our knowledge, this is the first report on the prevalence of E. shiquicus in dogs in Qinghai province. The current results improve our understanding of the transmission and dissemination of human echinococcosis and suggest that exposure to the eggs of E. multilocularis harbored by wild foxes and stray dogs may pose a great risk of alveolar echinococcosis to humans in Qinghai province.
