目的 调查研究四川省 1993 -2 0 0 1年钩端螺旋体 (简称钩体 )病传染源情况 ,为防治该病提供科学依据。方法 按全国钩体病监测方案全省选择 10个监测点 ,进行钩体病主要传染源调查。结果 黑线姬鼠带菌率占第 1位 ,主要携带黄疸出血群钩体 ,首次从牛尿中检出七日热群钩体 结论 鼠密度、鼠带菌率、带菌鼠密度分别与钩体发病率呈正相关。黑线姬鼠是四川省稻田型钩体主要传染源。耕牛作为七日热群钩体宿主和重要传染源应继续调查。
Objective To investigate the infectious origin of Leptospira (Leptospira) from 1993 to 2001 in Sichuan Province and provide a scientific basis for the prevention and treatment of the disease. Methods According to the national monitoring program of leptospirosis, 10 monitoring points were selected in the whole province to investigate the main sources of leptospirosis. Results The Apodemus agrarius belonged to the first place, carrying the hook body of hemorrhagic jaundice, and the conclu- sion of rodent density, rat carriage rate, Was positively correlated. Apodemus agrarius is the main source of infection in paddy field in Sichuan Province. Cattle as a seven-day hot cluster hook host and an important source of infection should continue to investigate.
