目的 了解在人蛔虫和猪蛔虫感染并存的农村社区内因交叉感染发生的可能性 ,猪蛔虫对人群蛔虫感染传播的作用。方法 选择两个基线情况基本相同的自然村 ,即江西省新建县樵舍乡蔓湖行政村的老支村和畔支村为实验现场。在对两村所有人群进行相同药物治疗处理的同时 ,对其中 1个村的猪群也进行治疗 ,并以约 2个月的间隔重复对猪治疗 2次 ,但对另一村的猪群不作治疗处理。在随后 1年内 ,约每 2个月 1次 ,用改良加藤法观察两村人群蛔虫感染的回升情况。结果 药物治疗后连续 5次横断面调查表明 ,人群蛔虫流行率和感染度在两村之间均无统计学差异 (χ2 <0 .6 5 8,F <1.6 5 8,P >0 .1)。结论 当地猪蛔虫的传播对人群蛔虫的传播无重要影响
Objective To understand the role of Ascaris suum in the transmission of Ascaris infection in rural communities where human Ascaris and Ascaris suum infection co-exist due to the possibility of cross-infection. Methods Two natural villages with the same baseline conditions were chosen as the experimental site, Laochai and Banci villages in Manhu Administrative Village, Qiaoshe Township, Xinjian County, Jiangxi Province. In the same medication treatment for all groups in both villages, swine herds in one village were also treated and pigs were treated twice in succession at intervals of about 2 months, but not in herds in another village Treatment treatment. In the next year, about once every two months, with improved Kato method observed two villages crowd roundworm infection recovery. Results Five consecutive cross-sectional surveys showed that there was no significant difference in the prevalence and infection of roundworms among the two groups (χ2 <0.056, F <1.658, P> 0.01) . Conclusion The local transmission of Ascaris suum has no significant impact on the spread of Ascaris in the population
