【摘要】 为比较塑料袋培养法与试管滤纸培养法和Kato-Katz法检查钩虫感染的效果,我们于1997年9月在南陵县奚滩乡中洲村进行了现场对比观察。结果在受检的158人中塑料袋培养法检出钩虫63例,阳性率为39.99％;试管滤纸培养法58例,阳性率36.71％;Kato-Katz氏法79例,阳性率50.0％。经两两配对比较,塑料袋培养法与试管法检出率差异无显著意义(x~2=0.757 P>0.05)。塑料袋法检出率低于Kato-Katz法,差异有高度显著意义(x~2=11.31 P<0.01)。3种方法总符合率为63.92％。提示无论那种方法检查钩虫感染,均有一定的漏检率。更多还原

【Abstract】 In order to evaluate the effect of filter paper strip culture method in plastic bag, filer paper strip cultuere method in tube, and Kato-Katz thick smear method for examination of hookworm infection, a field comparative observation was performed at Zhongzhou village, Xitan town, Nanling county in Sep.1997.158 residents were detected by three kinds of methods in the study.The results showed that the positive rate of hookworm by filter paper strip culture method in plastics bag, by the culture method in tube, and by Kato-Katz thick smear was 39.99%, 36.71%, and 50.0% respectively.There were no significant difference at two kinds of culture methods (χ~2=0.757 P>0.05).But the positive rate of hookworm by two kinds of culture methods was lower than by Kato-Katz thick smear method (χ~2=11.31 P<0.01).The crude agreement of three kinds of methods was only 63.92%.This result demonstrated that there was a high false negative rate for examination of hookworm infection by any one in the three kinds of methods.更多还原
