血吸虫病的诊断以粪中查出血吸虫卵最为确实,定量诊断尤为准确,且操作程序愈简便,造成技术误差的机会愈小。1954年Kato和Miura介绍了粪便厚涂片的检验技术,方法简便。此后几经改进,目前已广为采用。方法的准确性业经Katz N等(1968,1970)、Chaia G等(1968)和TeesdaleCH、Amin MA(1976)等学者多次实验证明,对粪中加入的虫卵,与其他方法相比,Kato厚涂片虫卵计数法回收率最高,检得的平均虫卵数亦居首位。作者在血吸虫病防治实际工作中发现用Kato法对同一受检者的两张平行涂片,镜下计得的虫卵数,往往先制备的一张多于后一张。为探讨存在上述现象的原因,通过实验观察发现Kato厚涂片虫卵数的
The diagnosis of schistosomiasis Schistosoma japonicum eggs to find the most accurate, quantitative diagnosis is particularly accurate, and the more simple the operation procedures, resulting in less technical error opportunities. In 1954, Kato and Miura introduced the inspection technique for thick stools and the method is simple and convenient. After several improvements, is now widely used. The accuracy of the method was verified by several experiments by Katz N et al. (1968, 1970), Chaia G et al. (1968) and Teesdale CH, Amin MA (1976) and others. Compared with other methods, Kato Thick smear eggs count the highest recovery rate, the average number of eggs detected also ranks first. In the practical work of schistosomiasis prevention and control, the author found that using Kato’s method to test two parallel smears of the same subject, the number of eggs counted under the microscope often more than one prepared later. In order to explore the reasons for the existence of the above phenomena, the number of ovo
