湖北某自然村斯氏并殖吸虫宿主感染情况与问卷调查

Paragonimus skrjabini Infection in Animal Reservoir Hosts and Questionnairing in Residents at a Village of Hubei Province

本文通过检测第二中间宿主锯齿华溪蟹(Sinopotamon denticulatum)、保虫宿主家猫和家犬感染斯氏并殖吸虫情况,以及问卷调查人群对斯氏并殖吸虫病认知、行为等方法,调查湖北省保康县尧治河自然村斯氏并殖吸虫病流行情况。结果表明,锯齿华溪蟹囊蚴感染率为20.5%(46/214),其中自然村磷矿开发区囊蚴感染率为15.6%(20/128),非开发区为30.2%(26/86),两者差异有统计学意义(χ2=6.5,P<0.05)。家猫感染率为25%(6/24),家犬感染率为17.6%(6/34),两者差异无统计学意义(χ2=0.46,P>0.05)。问卷调查结果表明,家猫与家犬均有溪沟觅食及排便行为。儿童有食生或半生溪蟹习惯。本地具备斯氏并殖吸虫病流行病学所需的自然生态环境,存在斯氏并殖吸虫病流行的威胁。

Freshwater crabs （Sinopotamon denticulatum） were examined for metacercariae. Cats and dogs were also examined for Paragonimus infection. Questionnairing was carried out on health knowledge and behaviors among local residents in a village of Baokang County, Hubei Province. Results showed that the infection rate of Paragonimus skrjabini metacercariae in Sinopotamon denticulatum was 20.5% （46/214）, with 15.6% （20/128） in a mining area and 30.2%（26/86） for the non-mining area respectively （Χ^2=6.5, P〈0.05）. The prevalence in cats and dogs was 25.0%（6/24） and 17.6%（6/34） respectively （Χ^2=0.46, P〉0.05）. Questionnairing showed that dogs and cats were with the habit of foraging and defecating at streams and children had the habits of eating raw or under-cooked crabs. The natural and ecological environments are in favor of the life cycle of P. skrjabini.
