【摘要】 目的了解湖南省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6个监测点采集健康人群血清,MAT法检测抗体,采用SPSS13.0分析。结果人群钩体抗体总阳性率为61.04%,男、女性阳性率分别为62.27%和60.06%(P>0.05)。10～19、20～29、30～39、40～49和50～岁年龄组抗体阳性率分别为43.01%、57.78%、60.76%、67.59%和69.23%(P<0.05)。宁乡县、湘潭县、双峰县、沅江市、浏阳市、醴陵市抗体阳性率分别为52.53%、62.50%、55.00%、73.79%、70.00%和51.00%(P<0.05)。赖、拜伦、澳洲、秋季、临海、七日热、犬、清水、波摩那、乌尔夫型抗体阳性率分别为30.19%、27.27%、23.70%、12.50%、8.77%、6.17%、5.36%、4.38%、3.41%和1.30%(P<0.05)。结论湖南省以黄疸出血群赖型、秋季群秋季型、拜伦群拜伦型、澳洲群澳洲型为主要血清型,抗体阳性率在地区、年龄、均存在差异。更多还原

【Abstract】 【Objectives】To explore the leptospirosis dominant serogroups and serovars and their distribution in Hunan province, so as to provide the scientific evidences for preventing and controlling leptospirosis. 【Methods】 According to the implement scheme of leptospirosis surveillance in 2007 in Hunan province, we carried on seroepi-demiology investigation with leptospirosis for healthy people in six surveillance areas. MAT method was adopted to detect the sera antibody, and the data was statisiticsed by SPSS 13.0 software. 【Results】The positive rate of the health people of 616 sera samples was 61.04%. The male positive rate was 62.27%, and the female positive rate was 56.63%, the difference was not significant (P>0.05). The positive rate in each age group was 43.01% (10～19), 57.78% (20～29), 60.76% (30～39), 67.59% (40～49), 69.23% (50～ ), respectively, and it had significant difference (P <0.05) among them. The positive rates were 52.53% (Ningxiang), 62.50% (Xiangtan), 55.00%(Shuangfeng), 73.79% (Yuanjiang), 70.00% (Liuyang), 51.00% (Liling), respectively, and it had significant difference (P <0.05) among them. The positive rate of each serovar was 30.19% (lai), 27.27% (ballum),23.70% (ausstralis), 12.50% (autumnalis), 8.77% (linhai), 6.17% (canicola), 5.36% (hebdomadis), 4.38% (cingshui), 3.41% (pomona), 1.30% (wolffi) re- spectively, and it had significant difference (P <0.05) among them. 【Conclusions】The serovars of leptospirosis pri- mary were Icte, Autu, Grip in Hunan province, and the infection rate were significant difference among surveillance areas, serotypes ,genders and age groups.更多还原
