南京市2007～2009年钩端螺旋体病血清学监测结果分析

目的了解南京市钩端螺旋体病流行的主要血清群（型）及其分布，为防治提供科学依据。方法在定点医院，采集疑似患者血清，MAT法检测抗体，采用SPSS13．0分析。结果866名疑似患者钩体抗体总阳性率为10．28％，男、女性阳性率分别为11．33％和8．39％（P〉0．05）。10～19岁、20～29岁、30—39岁、40～49岁和〉50岁年龄组抗体阳性率分别为0．12％、1．04％、2．19％、5．31％和1．62％（P〈0．05）。赖、澳洲、秋季、七日热、犬、波摩那、流感伤寒群抗体阳性率分别为1．85％、1．73％、0．58％、0．92％、0．35％、3．81％、0．46％（P〉0．05）。结论南京市以波摩那群波摩那、澳洲群澳洲型、黄疸出血群赖型为主要血清型，抗体阳性率在年龄分布上存在差异。

Sero - epidemiology surveillance about leptospirosis in 2007 - 2009 year of Nanjing

Objective To explore the leptospirosis dominant serogroups and serovars and their distribution in Nanjing, so as to provide the scientific evidences for preventing and controlling leptospirosis. Methods According to the implement scheme of leptospiresis surveillance in 2007 -2009 of Nanjing, we carried on seroepidemiology investigation with leptospirosis for suspected ease. MAT method was adopted to detect the sera antibody, and the data was statisitiesod by SPSS 13.0 software. Results The positive rate of the suspected case of 866 sera samples was 10.28%. The male positive rate was 11.33%, and the female positive rate was 8.39%, the difference was not significant （P 〉0 05 ）. The positive rate in eachage group was 0. 12% （ 10 - 19）, 1.04% （20 - 29） ,2.19% （30 - 39）, 5.31% （40 - 49）, 1.62% （ 〉 50 ）, respectively, and it had significant difference （ P 〈 0.05 ） among them. The positive rate of each serovar was 1.73 % （ausstralis） , 0. 58 % （ autumnalis）, 1.85 % （lai） ,0.35 % （ eanicola）, 0.92 % （ hebdomadis）, 3.81% （ pomona）, respectively, and it had not significant difference （ P 〉 0.05 ） among them, Conclusion The serovars of leptospiros is primarywere Icte. Autu, Pomona Grip in Nanjing, and the infection rate are significant difference among age groups.
