对于钩虫病的病原学诊断已有许多方法,在流行病学调查及普查过程中,无论哪种方法均有假阴性出现,各种方法的符合率也不十分理想。除去检查方法本身的局限性外,虫卵在粪便中的分布情况也可能影响虫卵的检出率。为此,我们于1988年5至6月分别采用改良加藤氏厚片法(简称定透法)及加藤定量—塑料圆管饱和盐水漂浮计数法(简称定漂法)对三份不同
There are many methods for the diagnosis of hookworm etiology. During epidemiological investigation and census, no matter which method has false negative, the coincidence rates of various methods are not very satisfactory either. In addition to the limitations of the inspection method itself, the distribution of eggs in the stool may also affect the detection rate of eggs. To this end, we used the modified Katsushika thick slice method (referred to as constant penetration method) and the Kato quantitative-plastic tube saturated brine floating count method (referred to as the fixed drift method) from May to June 1988 for three different
