摘要
目的掌握沅江市钩体病宿主动物鼠的种类、密度以及感染率,了解健康人群对钩体病的免疫水平,为进一步做好钩体病的预防与控制提供依据。方法按照《湖南钩端螺旋体病监测实施方案》开展鼠类带菌调查,对健康人群血清学监测。结果 4年平均鼠密度为4.76%。鼠种构成以东方田鼠和黑线姬鼠为优势属种,总阳性率为5.41%,各年间、夏季和秋季间阳性率差异无统计学意义(P>0.05),病原学分型以赛罗群为主。人群钩体抗体阳性率平均为60%,年龄、性别、年份人群钩体抗体阳性率差异无统计学意义(P>0.05)。结论沅江市宿主动物钩体带菌率低,血清学显示人群钩体隐性感染率较高,需要采取综合防制措施以进一步控制钩体病疫情。
Objective To know the host animals,rodent density,and infection rates of leptospirosis in Yuanjiang,to understand the immune level of leptospirosis in healthy population,and to provide a basis for further controlling and preventing leptospirosis.Methods In accordance with ＂Implementation Scheme of Leptospirosis Surveillance in Hunan Province＂,the infection rate of rodents was investigated and serological surveillance of healthy population was conducted.Results The average rodent density during the period of 2005～2008 was 4.76%.Microtus fortis and Apodemus agrarius were the dominant species,with the total positive rate of 5.41%.No statistically significant difference was found in the positive rate between the summer and autumn and among each year （P〈0.05）.Cerro group was dominant by etiology-based classification.The average positive rate of leptospira antibody in population was 60%,and there was no statistically significant diff-erence in the positive rate among age group,sex,and years （P〉0.05）.Conclusions The leptospira carrier rate of host animals is low in Yuanjiang.The sero-epidemiological results show that the recessive infection rate of leptospira in population is quite high.It is necessary to take comprehensive control measures for further controlling the epidemic of leptospirosis.
