Abstract: Objective To understand the status of field feces in Jingzhou City, so as to provide the evidence for improving the control measures to interrupt the transmission routes of schistosomiasis. Methods The distribution of field feces was investigated in 27 schistosomiasis endemic villages in Gong’ an，Jianli，Jiangling，Honghu and Shishou counties（cities）from 2010 to 2012. The schistosome positive status of the field feces was surveyed with the hatching method. Results There were 1 366 field feces and the average density was 0.089 2 feces per 100 square meters in this survey. The cattle feces，human feces，dog feces and elk feces respectively accounted for 99.71%，0.07%，0.15% and 0.07% in the survey. The infection rates of the field feces were 1.46% and 2.42% in the channels and bottomlands，respectively（P > 0.05） . The average rate of infected field feces was 3.21% in 2010，0.36% in 2011，and 1.60% in 2012，and the difference between 2010 and 2012 was not statistically significant（P > 0.05） . Conclusions The main field feces come from cattle，and the main distribution of infected field feces is in channels and bottom? lands. Therefore， the management of cattle and treatment of field feces should be strengthened.

摘要： 目的 目的 了解湖北省荆州市血吸虫病流行区野粪分布和阳性情况， 为阻断血吸虫病传播途径提供科学依据。方 方 法 法 2010-2012年对公安县、 监利县、 江陵县、 洪湖市和石首市27个血吸虫病流行村的野粪分布情况进行调查， 并采用顶管 孵化法调查野粪阳性情况。 结果 结果 2010-2012年共调查1 366份野粪， 其平均密度为0.089 2份/100 m2 ， 其中牛粪、 人粪、 犬 粪、 麋鹿粪分别占99.71%、 0.07%、 0.15%、 0.07%。野粪主要分布在沟渠和外滩； 两环境野粪平均密度为0.090 9份/100 m2 和 0.084 8份/100 m2 ， 阳性率分别为1.46%和2.42%， 差异无统计学意义 （χ2 = 0.20， P > 0.05）。2010-2012年阳性野粪均为牛 粪； 野粪阳性率分别为3.21%、 0.36%和1.60%，2012年野粪阳性率较2010年下降了50.08%， 差异无统计学意义 （χ2 = 2.27，P > 0.05）。结论 结论 荆州市野粪种类以牛粪为主， 阳性野粪主要分布于沟渠和外滩； 加强耕牛管理和野粪处理对控制 血吸虫病流行具有重要意义。
