血吸虫病流行病学调查中三种检测方法的比较研究

COMPARISON OF THREE DETECTION METHODS FOR THE EPIDEMIOL OGICAL INVESTIGATION OF SCHISTOSOMIASIS

应用粪便检查、环卵沉淀试验（ＣＯＰＴ）、金黄色葡萄球菌Ａ蛋白协同凝集试验（ＳＰＡ一ＣｏＡ）３种方法检测血吸虫病流行区居民３６２例，粪检、ＣＯＰＴ和ＳＰＡ一ＣｏＡ阳性率分别为８．８４％，３４．２５％和１６．３０％。ＣＯＰＴ与粪检阳性符合率９０．６２％，ＳＰＡ一ＣｏＡ与粪检阳性符合率９３．７５％；ＣＯＰＴ与粪检阴性符合率７１．２１％，ＳＰＡ一ＣｏＡ与粪检阴性符合率８６．３０％。正常人血清９５例，ＣＯＰＴ均阴性，ＳＰＡ一ＣｏＡ阳性率３．１６％。调查结果表明，ＳＰＡ一ＣｏＡ方法有较高的敏感性，在血吸虫病流行病学调查中，是一种较好的方法。

The positive rates of fecal examination,COPT and SPA一CoA for schistosomiasis were 8.84%,34.25%and 16.30% respectively from 362 residents lived in an endemic area of thedisease. The positive coincidence rates were 90.62% between results of COPT and fecal examinationand 93. 75%between results of SPA一CoA and fecal examination. Meanwhile, 95 sera from healthypeople all negative by COPT and 3.16% of positive rate by SPA一CoA. These results indicate thatSPA一CoA is of a certain specificity and higher sensitivity.It is a better method for the epidemiologi-cal investigation of schistosomiasis.
