摘要
目的了解湛江市农村人群肠道蠕虫感染现状。方法随机采集村民新鲜粪便,用直接涂片法及饱和盐水浮聚法检查虫卵,用盐酸左旋咪唑驱虫法检查感染钩虫种类。结果粪检190人,虫卵阳性78人,总感染率为41.1%。检出3种肠道蠕虫卵,其中钩虫感染率25.8%,蛔虫感染率12.1%,鞭虫感染率10.5%,有2种或3种虫卵阳性率为6.8%;不同地点各虫感染率不同;钩虫以50~70岁人群感染率较高,蛔虫、鞭虫以20岁以下人群常见;女性的钩虫感染率明显高于男性。药物驱虫后检获有十二指肠钩虫成虫、美洲钩虫成虫及雄性蛔虫,其中,十二指肠钩虫占钩虫比例87.4%,美洲钩虫占钩虫比例12.6%。结论湛江市农村人群感染蛔虫、鞭虫及钩虫常见,其中以钩虫感染最为严重。钩虫感染率较高与旱作生产生活方式密切相关。十二指肠钩虫在该地钩虫流行中占了重要地位。
