Abstract:

目的分析天津市农牧地区高危人群蚤传及螨传立克次体病流行趋势.方法 2007-2009年,利用现场流行病学调查方法,以农户为单位随机调查天津地区直属的8个区(县)从事农牧业的人群,并现场采集886份血液标本,采用微量间接免疫荧光检测人群莫氏立克次体、横赛巴尔通体及恙虫病东方体特异IgG抗体,并分析比较不同年份、地区、性别及年龄组人群抗体阳性率变化趋势.结果 3种立克次体抗体阳性率均呈上升趋势.其中莫氏立克次体阳性率变化范围为5.0%～58.2%;横赛巴尔通体为2.6%～14.5%;恙虫病东方体为1.8%～39.8%.3种病原体阳性率较高的地区主要集中在天津市东南部及中部近海低海拔地区.结论天津地区农牧人群普遍存在蚤传及螨传立克次体感染,并且有逐年上升趋势.

English Abstract:

Objective To study the sero-epidemiological starus regarding Rickettsia (R.) typhi,Bartonella (B.) henselae and Orientia (O.) tsutsugamushi in farmers from rural areas of Tianjin.Methods Field epidemiological surveys were performed in 8 districts (county) of Tianjin city from 2007 to 2009.886 farmers were randomly recruited and their serum samples collected to detect the specific antibodies of R.typhi,B.henselae and O.tsutsugamushi by micro-indirect immunoflorescence (IFA).Results The total antibody positive rates of R.typhi increased from 5.0% to 58.2% while B.heaselae had an increase from 2.6% to 14.5% and O.tsutsugamushi increased from 1.8% to 39.8%.Geographic distribution showed that farmers living in the central and southeast areas were higher than that in other areas.Conclusion Infections of both R.typhi,B.henselae and O.tsutsugamushi in farmers from Tianjin areas were popular and the antibody positive rates ofR.typhi,B.henselae and O.tsutsugamushi had an annual increase.
