【摘要】 目的评价日本血吸虫抗独特型抗体NP30抗体检测法在云南大山区血吸虫病流行现场的应用效果。方法对云南大山区血吸虫病流行区的506位居民进行粪检,同时用NP30抗体检测法和血吸虫抗体ELISA检测试剂盒(SEA-ELISA)分别对其血清进行检测,评价NP30抗体检测法的敏感性;同时检测非流行区的100份血清确定其特异性。结果NP30抗体检测法和SEA-ELISA法的粪检阳性符合率分别为87.80%(144/164)和84.76%(139/164);两者的特异性分别为96.00%(96/100)和94.00%(94/100),差异均无显著性(P均>0.05),但在粪孵阴性人群血清样本中,NP30抗体检测法和SEA-ELISA法的检出率分别为44.15%(151/342)和70.47%(241/342),差异有显著性(P<0.05)。结论NP30抗体检测法可用于云南大山区血吸虫病筛查。更多还原

【Abstract】 Objective To evaluate the potency of NP30 antibody detection for the diagnosis of schistosomiasis japonica in the mountainous endemic spots in Yunnan Province. Methods A total of 506 inhabitants in the mountainous schistosomiasis endemic regions of Yunnan Province were examined by using the stool hatching test for parasitological stool examination; the sera samples from 506 villagers were tested with NP30 antibody detection and SEA-ELISA for immune examination respectively, and the sensitivity of NP30 antibody detection was estimated . Their specificity was determined by testing 100 sera from nonepidemic scenes. Results The positive coincidence of stool hatching test with NP30 antibody detection and SEA-ELISA were 87.80%(144/164)and 84.76%(139/164) respectively, and their specificity as 96.00%(96/100)and 94.00%(94/100), with no significant difference between them (P>0.05). However, in the negative sera from stool hatching test, the detection rate was 44.15% (151/342) by NP30 antibody detection, and 70.47%(241/342)by SEA-ELISA, the difference was significant(P<0.05). Conclusion NP30 could be used in the mountainous area of Yunnan Province for the diagnosis of schistosomiasis japonica.更多还原
