本文在各种类型的基本消灭血吸虫病疫区抽查一批居民,采用粪检(三逆三检或一送三检,沉孵结合),并在同一批受检者进行了直检作比较,看出距灭螺时间越长,灭螺质量越好,则粪检阳性率越低,但直检阳性率下降幅度小,在过去从未用过直检法的地区,直检常可查出历年粪检阴性的大部分患者。但是在受检的1,383人中粪(+)直(-)者也占6.94%,所以在已基本消灭血吸虫病的地方查病时粪检法仍是一种不可缺少的方法。本文还讨论了皮试、环卵沉淀试验等法对于这些地区查病的意义。
This article in a variety of basic eliminate schistosomiasis epidemic spot checks a group of residents, the use of fecal seizures (three check three or one get three seizures, combined with incubation), and in the same batch of subjects were compared for direct inspection The longer the distance from the snail, the better the snail quality, then the lower the positive rate of fecal examination, but the direct test positive rate of decline is small, in the past has never been used in areas where the direct test method can be found in the calendar year Fecal negative majority of patients. However, the fecal (+) straight (-) person also accounted for 6.94% of the 1,383 people examined, so fecal examination was still an indispensable method when checking the disease where the schistosomiasis has basically been eliminated. This article also discussed the skin test, egg and egg precipitation test method for the detection of these areas significance.
