血吸虫病仍然是世界上最重要的被忽视的热带疾病之一，中国是日本血吸虫病的地方病。随着血吸虫病防治取得的巨大成就，中国政府提出了到2030年在国家一级消除寄生虫病的目标。然而，一个主要的挑战是中间宿主钉螺的栖息地仍然很大。每年报告的新出现的蜗牛栖息地数量不断增加，进一步加剧了这一问题。因此，研究该地区钉螺的种群遗传学特征，对评价钉螺控制效果和扩散具有重要意义。然后，我们在江苏太仓新出现的栖息地采集了钉螺样本。在2014 - 2017年的日本血吸虫非流行区，基于9个微卫星进行了群体遗传分析。结果表明，各螺类群体的遗传多样性较低，大多数遗传变异来源于螺类群体内部。2015年人口的估计有效人口规模是无限的。所有的蜗牛都可以分为两个集群，进一步的DIYABC分析显示，2016年和2017年的种群都可能来自2015年，这表明2017年的种群在2016年进行的实地调查中肯定被遗漏了。这些发现可能对制定更实用的蜗牛监测和控制指南具有影响。
Schistosomiasis is still one of the most significant neglected tropical diseases worldwide, and China is endemic for Schistosoma japonicum. With its great achievement in schistosomiasis control, the government of China has set the goal to eliminate the parasitic disease at the country level by 2030. However, one major challenge is the remaining huge areas of habitats for the intermediate host Oncomelania hupensis. This is further exacerbated by an increasing number of new emerging snail habitats reported each year. Therefore, population genetics on snails in such areas will be useful in evaluation of snail control effect and/or dispersal. We then sampled snails from new emerging habitats in Taicang of Jiangsu, China, a currently S. japonicum non-endemic area from 2014 to 2017, and performed population genetic analyses based on nine microsatellites. Results showed that all snail populations had low genetic diversity, and most genetic variations originated from within snail populations. The estimated effective population size for the 2015 population was infinitive. All snails could be separated into two clusters, and further DIYABC analysis revealed that both the 2016 and the 2017 populations may derive from the 2015, indicating that the 2017 population must have been missed in the field survey performed in 2016. These findings may have implications in development of more practical guidelines for snail monitoring and control.
