本文应用青海囊型包虫抗原 Dot- EL ISA、IHA和新疆囊型包虫抗原 EL ISA、泡型包虫 EM18抗原 EL IB对流行病学调查现场的 2 0 6例包虫病人血清进行了检测。结果表明青海囊型包虫抗原 Dot- EL ISA和 IHA对囊型包虫病人血清的阳性率分别是 90 .37%和 91.98% ;新疆囊型包虫抗原 EL ISA对囊型包虫病人血清的阳性率为 75 .94% ;三种方法对钙化灶型囊型包虫病人血清的阳性率分别是 77.2 7%、81.82 %和 6 5 .91% ,显著低于其它囊型包虫病人血清的阳性率 ;阴性者主要是单纯性肺脏和肝脏囊型包虫病人血清。3种方法 B超、X线诊断的泡型包虫病人的血清阳性率均为 10 0 .0 %。泡型包虫抗原 EM18-EL IB检测结果表明 ,B超 ,X线诊断的泡型包虫病人血清阳性率为 73.6 8% ;囊型包虫病人血清阳性率为 5 .88% ,其中钙化灶型病人血清阳性率为 15 .91% ;阳性血清数与阴性血清数比例约为 1:7(2 5 :181)。对不同方法在囊型和泡型包虫病诊断与鉴别诊断中的价值及意义进行了讨论
In this paper, Dot-EL ISA, IHA and EL ISA of Xinjiang cystic echinococcosis antigen and EL IB of EM18 antigen of hydatid cyst were used to detect the serum of 206 hydatid disease patients in the field of epidemiology Detection. The results showed that the positive rates of Dot-EL ISA and IHA in Qinghai cysts were 90.37% and 91.98%, respectively. The EL ISA of Xinjiang cystic echinococcosis patients The positive rate of serum was 75.94%. The positive rates of three methods were 77.27%, 81.82% and 65.91% respectively, which were significantly lower than those of other cystic echinococcosis Serum positive rate of patients; negative were mainly pure lung and liver cystic hydatid sera. The seroprevalence of three methods of B ultrasound and X-ray diagnosis of hydatid disease patients were 100%. The results of EM18-EL IB assay showed that the seroprevalence of the B hydrometery patients diagnosed by B ultrasound and X-ray was 73.6 8%, and the seropositivity rate of cystic echinococcosis was 5.88% Serum positive rate of calcification type patients was 15.91%; the ratio of positive serum to negative serum was about 1: 7 (25:181). The value and significance of different methods in the diagnosis and differential diagnosis of cystic and alveolar echinococcosis
