广东省清远市2007年钩端螺旋体病监测分析

目的对2007年广东省清远市钩端螺旋体病（以下简称钩体病）疫情、人群及宿主动物监测情况进行分析，为制定防治措施提供科学依据。方法采集相关人群及宿主动物血清，用显微镜凝集试验（MAT）进行抗体测定；采集相关人群全血、宿主动物脏器做钩端螺旋体分离培养及分群鉴定。结果报告钩体病8例，发病率0．23／10万。流行前健康人血清抗体阳性率为19．897％，菌群以黄疸出血热为主；流行后期健康人血清体抗阳性率为15．54％，菌群以七日热为主；流行期疑似病人血清抗体阳性率为0．88％，菌群为七日热。鼠血清抗体总阳性率为18．15％，黄毛鼠、板齿鼠、褐家鼠、臭鼬鼯和施氏屋顶鼠的血清抗体阳性率在14．08％～50．00％之间，菌群以秋季热群为主，其次为波摩那群，黄胸鼠和青毛鼠血清抗体阳性率为零；水禽（鸭）血清抗体阳性率为2．0％，菌群为犬热群。未从人群及宿主动物中分离出钩端螺旋体。结论该市人群及宿主动物钩体病隐性感染水平均较高，出现钩体病发病年龄组后移。
