目的了解宁夏泾源县人群棘球蚴抗体水平,为开展综合防控工作提供参考依据。方法采用整群随机抽样方法,于2012年在全县按照东、西、南、北、中不同方位抽取5个乡镇,每个乡镇随机抽取3个村共15个村作为调查点,对其3周岁以上、外出时间不超过半年的常住居民,采用酶联免疫吸附试验(ELISA)方法测定其血清包虫IgG抗体。结果调查3 181人,阳性血清84人份,阳性率2.64%;半个山村人群棘球蚴抗体阳性率最高(8.15%),且不同村人群抗体阳性率差异有统计学意义(χ2=12.85,P<0.05);感染主要以60~岁、牛羊屠宰及皮毛贩运者、回族、信仰伊斯兰教等人群为主;男、女性别血清抗体阳性率间差异无统计学意义(P>0.05)。结论棘球蚴病在泾源县的部分地区广泛流行,且牛羊屠宰及皮毛贩运者、60岁以上等人群感染率较高,提示应加强重点地区、重点人群的防控工作。
Objective To understand the level of hydatid antibody in the population of Jingyuan County in Ningxia, and to provide a reference for carrying out comprehensive prevention and control work. Methods A cluster random sampling method was used to select 5 townships in different orientations in East, West, South, North and North of China in 2012. 15 villages of 3 villages were randomly selected from each township for investigation. Permanent residents over the age of, less than six months out of time residents, enzyme-linked immunosorbent assay (ELISA) method for the determination of serum ejaculated IgG antibody. Results A total of 3 181 and 84 positive samples were obtained. The positive rate was 2.64%. The positive rate of echinococcosis antibody was the highest (8.15%) in half of the village population, and the positive rate of antibody in different village groups was statistically significant (χ2 = 12.85, P <0.05). The infection mainly occurred in people aged 60 ~, cattle and sheep slaughtered and trafficked, Muslims and Islam. There was no significant difference in the positive rate of serum antibody between male and female (P> 0.05). Conclusion Echinococcosis is widely prevalent in some areas of Jingyuan County. In cattle and sheep slaughter and fur traffickers, the infection rate is higher in people over 60 years of age, suggesting that the prevention and control of key populations and key populations should be strengthened.
