【摘要】 目的了解达州市人群和宿主动物钩端螺旋体菌群分布和变动情况,分析其流行规律,为预防和控制钩体病提供科学依据。方法按照《全国钩端螺旋体病监测实施方案》,对宿主动物密度、构成、带菌以及健康人群血清抗体检测,对资料进行描述性流行病学分析。结果 2013-2015年,达州市监测点平均鼠密度为12.08%,鼠种以四川短尾鼩为主(73.79%);采集鼠肾、猪肾、蛙肾1 016份,未检出钩体菌株;采集健康人群血清300份,检出4个血清群,以黄疸出血群为主,阳性检出率以高龄组居多。结论达州市近年来无钩体病例报告,鼠种构成发生变化,宿主动物中未检出钩体菌,抗体阳性者以历史感染为主,发生暴发流行的风险不高。更多还原

【Abstract】 Objective To investigate distribution and changes of florae of leptospira in men and host animals in Dazhou and analyze the prevalence pattern so as to provide scientific evidence for prevention and control of leptospirosis. Methods According to the National Program for Surveillance of Leptospirosis,the density,constitution and germ carrying of host animals were investigated,and serum antibody tests of healthy people were carried out; the data was analyzed by descriptive epidemiological methods. Results During the period from 2013 to2015,the average rodent density at surveillance sites in Dazhou was 12. 08%,and the major specie was anourosorex squamipes( 73. 79%). 1 016 samples of rodent kidneys,pig kidneys and frog kidneys were analyzed,and no leptospira strain was detected. 300 serum samples of healthy people were analyzed,and four serum groups were detected,with jaundice hemorrhage group accounting for the largest portion; the positive antibody detection rate was the highest in the high-age group. Conclusion No leptospirosis has been reported in Dazhou in recent years; the rodent species composition has changed; leptospira has not been detected from host animals; positive antibodies originate mainly from historical infection; the risk of outbreaks is not high.更多还原
