农村集体服药后肠道线虫感染情况调查

目的了解深圳市龙岗区居民集体服药驱除肠道线虫效果。方法于2006年9月对肠道线虫感染高的龙岗区区居民集体服甲苯咪唑糖片驱虫，2007年1月经盐水漂浮法和改良加藤氏法粪检调查550名居民的感染情况，分析驱虫效果。结果肠道线虫卵总检出率为18．73％（103／550）。单虫阳性率以鞭虫卵最高，为9．27％，钩虫卵次之，为6．36％，蛔虫卵最低，为4．00％。用饱和盐水漂浮法检出率为8．18％；改良加藤氏法检出率为10．36％，经统计学处理（x^2=1．296，P〉0．05），无统计学意义。从单虫检出情况看，盐漂法检出钩虫卵阳性21人，加藤法为13人，经统计学处理无统计学意义（x^2=3．379，P〉0．05）。蛔虫卵分别检出16人和6人，显示盐漂法明显高于加藤法（x^2=4．638，P〈0．05）。鞭虫卵检出分另0为12人和39人，显示加藤法明显高于盐漂法（x^2=29．987，P〈0．01）。结论甲苯咪唑糖片对人体肠道线虫有良好的驱除效果。通过集体驱虫后当地肠道线虫感染率大副下降。
