【摘要】：目的调查洱源县血吸虫病达传播控制标准后流行区小兽及其他终末宿主感染血吸虫情况,探讨其在云南省高原山区血吸虫病传播中的作用。方法 2010-2011年采用夹夜法在洱源县村庄周围农耕区有螺环境内捕获小兽,分类鉴定后解剖观察和检查粪便,了解血吸虫感染情况;同时采用常规方法开展人、畜血吸虫病及螺情调查。结果捕获小兽3目3科4属6种307只,捕获率为12.79%,以斯氏家鼠和齐氏姬鼠为主,分别占捕获总数的53.75%和20.85%,解剖检查305只,1只斯氏家鼠感染血吸虫,感染率为0.61%(1/165),小兽感染率为0.33%(1/305),斯氏家鼠EPG(喁)为0.291,小兽群EPG(喁)为0.157;调查点自然村人群、牛、马和犬感染率分别为1.01%(6/597)、0.83%(5/599)、0.58%(1/173)和5.91%(13/220),人群、牛群、马群和犬群EPG(喁)分别为0.009~0.010、0.005、0.007和0.080,其他家畜未查出血吸虫感染;小兽与犬感染率差异有统计学意义(χ2=15.339,P0.05),小兽与其他宿主感染率间差异均无统计学意义;钉螺密度不断下降,未检出阳性。结论采集点小兽血吸虫感染率较低,在传播控制达标地区仍需进一步监测调查。
[Abstract]:Objective to investigate the infection of schistosomiasis in small animals and other terminal hosts in Eryuan County after reaching the transmission control standard, and to explore the role of schistosomiasis in schistosomiasis transmission in mountainous areas of Yunnan Province. Methods from 2010 to 2011, small animals were captured in the farming area around the village of Eryuan County by night clamping method. After classification and identification, the feces were dissected and examined to understand the infection of Schistosoma japonicum. At the same time, routine methods were used to investigate schistosomiasis and snail situation in human and livestock. Results 307 animals of 3 orders, 3 families, 4 families and 6 species were captured, and the capture rate was 12.79%. The main catch rate was 53.75% and 20.85%, accounting for 53.75% and 20.85%, respectively. 305 mice were dissected and one of them was infected with Schistosoma japonicum. The infection rate was 0.61% (1 鈮，
