[目的 ]调查鼠类在云南省血吸虫病流行区的传播作用。 [方法 ]用Kato Katz法对鼠类、人群及家畜进行同步调查。 [结果 ]鼠类感染率为 0 .9% (32 / 3 411) ,人群为 15 .6 % (4 6 1/ 2 96 4) ,家畜为 9.6 % (2 39/ 2 482 ) ;感染度EPG( X)鼠类为 5 .77,人群为 1.72 ,家畜为 0 .0 32 ;日粪虫卵数EPD共 3 16 2 40 6个 ;各种宿主所占比重RIT中人群占6 3 .10 % ,家畜占 2 8.32 % ,鼠类占 8.5 8% ;潜在污染指数IPC ,人群 344 .0 7,鼠类 71.83。[结论 ]鼠类在我省部份高原峡谷型血吸虫病流行区传播中的作用居于次要地位 ;在高原平坝型血吸虫病流行区传播中的作用居于再次要地位。
[Objective] To investigate the transmission of murine in the endemic area of schistosomiasis in Yunnan Province. [Method] The Kato Katz method was used to synchronize the investigation of mice, people and livestock. [Results] The infection rate of rats was 0.9% (32/3 411), the population was 15.6% (461/2 964) and the livestock was 9.6% (2 39/2 482) (X) mice was 5.77, the population was 1.72, and the number of livestock was 0.322. The number of eggs on day 1 was 3 16 2 40 6, and the proportion of various hosts accounted for 63.10% , Livestock accounted for 2 8.32% and rats accounted for 8.5 8%; potential pollution index IPC, population 344.07, mice 71.83. [Conclusion] The rodents play a secondary role in the transmission of endemic schistosomiasis in some plateau in our province, and play a second role in the spread of endemic areas of the Pingba schistosomiasis in the plateau.
