ELISA method was used for comparison. Results The positive rate of DIGFA in testing the serum from 50 infected rats was 96.0%(48/50). The negative rate of DIGFA in healthy rats was 100%(50/50). Cross reaction with Enteroclysis (13 samples) and Tapeworm (11 sqamples) was not observed. The cross reaction rate in 18 Strongyloidiasis rats was 5.6%. The sensitivity and specificity of DIGFA is comparable with ELISA (96.7%).

结果 用DIGFA检测广州管圆线虫实验感染鼠血清50份，其阳性检出率为96.0%，50份正常鼠血清的阴性符合率达100%，DIGFA分别检测蛲虫阳性鼠血清13份，绦虫阳性鼠血清11份和粪类圆线虫阳性鼠血清18份，前二者均为阴性，后者交叉反应率为5.6%；DIGFA与ELISA平行检测30份广州管圆线虫阳性鼠血清，两法符合率达96.7%。

The results showed that in evaluation of the method by detecting 50 RHD 1227A positive and 50 RHD 1227A negative individuals, the genotyping method displayed a sensitivity of 100% and a specificity of 100%; in evaluation of the method by detecting 33 DEL positive and 89 DEL negative individuals, the sensitivity was 100%, however, there were two serologically negative samples which were confirmed as positive using genotyping method.

结果表明：在50例RHD 1227A阳性和50例RHD 1227A阴性的Rh阴性样本中基因分型方法的灵敏度和特异性都是100％；在33例DEL阳性样本和89例DEL阴性的样本中，基因分型方法的灵敏度为100％，有2例样本血清学结果为阴性而基因分型结果为阳性，重新用血清学方法和序列分析方法复核这2例样本，发现2例都是血清学漏检，因而基因分型方法的特异性是100％。

The results showed that in evaluation of the method by detecting 50 RHD 1227A positive and 50 RHD 1227A negative individuals, the genotyping method displayed a sensitivity of 100% and a specificity of 100%; in evaluation of the method by detecting 33 DEL positive and 89 DEL negative individuals, the sensitivity was 100%, however, there were two serologically negative samples which were confirmed as positive using genotyping method. After re-testing these two samples with serological method and sequence analysis, it was found that original serological method gave false negative results and genotyping method still showed 100% specificity. The minimal target DNA concentration of this genotyping method is 8.13 ng/μl.

Anti-MOG and anti-MBP antibodies predicted more frequent and earlier relapses. Of 39 seronegative patients, nine (23%) had a relapse, and time to relapse was 45 13.7 months. Of 22 patients with anti-MOG and anti-MBP, 21 (95%) relapsed, and mean time to relapse was 7.5 4.4 months. Of 42 patients with only anti-MOG, 35 (83%) relapsed within 14.6 9.6 months P .001 for both comparisons with antibody-seronegative patients.
