目的通过分析钩端螺旋体病血清学结果,了解和掌握广东地区人群中钩体抗体水平及菌群的变化特征。方法参照WS290-2008行业标准方法采用显微镜凝集试验(MAT)方法进行血清学检测。结果2002～2008年共接收疑似患者血清1180份,其中凝集试验阳性23例,阳性率为1.95%(23/1180),分属6种菌群,其中黄疸出血、爪哇、秋季热及七日热4个群占了86.96%。结论广东省人群钩端螺旋体感染率呈逐年下降趋势,部分菌群出现更迭,在防治工作中应注意菌群变化。
Objective To understand and master the antibody level of leptospira and the characteristics of flora in Guangdong province by analyzing serological results of leptospirosis. Methods The method of microscopic agglutination test (MAT) was used to carry out serological tests according to WS290-2008 industry standard method. Results A total of 1180 serum samples were collected from 2002 to 2008, of which 23 were positive for agglutination test. The positive rate was 1.95% (23/1180), which belonged to 6 kinds of bacteria, including jaundice, Java, autumnal heat and seven-day fever 4 groups accounted for 86.96%. Conclusions The population infection rate of Leptospira in Guangdong Province shows a declining trend year by year, with some flora changing. In the prevention and control work, attention should be paid to the change of flora.
