To evaluate the diagnostic value of a single-serum Widal agglutination test (WAT) for patients with suspected paratyphoid fever A.
目的：评价疑似甲型副伤寒病例单份血清肥达凝集试验（WAT）的诊断价值。
Although non typhoidal febrile children manifested false positive Widal test, agglutinin level at titre of 1 ∶ 800 was only found in a few patients.
虽然非伤寒患儿肥达反应可呈假阳性反应，但O、H抗体凝集效价极少达到1∶800。
Objective:To reevaluate the diagnostic value of Widal test and some problems concerned in children with typhoid fever.
目的：评价肥达反应在儿童伤寒的诊断价值以及应注意的问题。
To evaluate the diagnostic value of a single-serum Widal agglutination test for patients with suspected paratyphoid fever A.

〔 Methods 〕 The pathogenic bacteria were cultured using the blood and bone marrow excrement biochemistry, serum agglutinin test, Widal reaction, ELISA and medicine sensitivity test.
〔方法〕采用血、骨髓、粪便病原菌培养方法、生化反应、血清凝集实验、肥达氏反应、抗原酶联免疫实验方法和药物敏感性试验。
The Widal test positive rate and IHA positive rate of 34 cases arc 91.2% and 94.4% respectively, but the latter's titre is higher than the former.
34例患者的Widal反应和IHA阳性率分别为91.2%和94.1%，但后者滴度较高。
Results: There was significant difference in positive rate of Widal test between the typhoid fever group and the non typhoidal fever group (97% vs 4%, P0.001).
结果：伤寒组肥达反应的肥达反应阳性率为97%（84/87），非伤寒组为4%（40/922），两组比较差异有极显著意义，P0.001。

The normal extent of Widal test on 100 cases of healthy donor in Dalian
大连地区100例健康人肥达氏试验正常值的评价
Of 106 serum samples which showed positive results in Widal test, the positive rate of this assay were 93.4% (99/106).
在肥达试验阳性的血清标本106例中，本法的阳性率为93.4%（99／106）。
Results The positive rate of immunoassay of typhoid (ELISA) and LPS-PHA in typhoid individuals were 85.4%, 80.5% on 7th day, both of them were much higher than those of blood culture and Widal test (P < 0.05).
结果伤寒杆菌抗原酶免法（ELISA）、LPS-PHA在第7d的检出率分别为85.4%和80.5%，显著高于血培养和肥达氏反应（P<0.05）。
Sensitivities (indicated by GMT) of the antisera H and O by this system were 6-7 times higher than that by routine ELISA, and 11-12 times by Widal test.
检出抗H及抗O抗体的敏感性（以GMT计），较常规ELISA高6～7倍；较传统的肥达氏试验高11～22倍。
Conclusion: Widal test is still considered to be a reliable and significant test for the diagnosis of typhoid fever in children with negative bacterial culture, and its diagnostic value should be confirmed.
结论：肥达反应仍是当今诊断儿童伤寒尤其是细菌培养阴性的伤寒患儿的可靠、有意义的辅助性诊断指标，其诊断价值应得到肯定。
Only 49 cases (62.0%) had positive widal test. The positive rate was higher in the patients with typhoid fever than in the patients with paratyphoid fever (73.3% and 26.3%, respectively; P < 0.05).
79例病人仅有49例（62.0%）肥达氏反应阳性，其中伤寒病人的阳性率明显高于副伤寒病人，分别为73.3%与26.3%（P<0.05）；
Blood culture remains the gold standard diagnostic method for diagnosis of typhoid fever. The positive rate of Widal test is low, but it is still of great significance for the cases with negative bacterial culture. 5.
血培养仍是伤寒诊断的金标准，肥达反应阳性率低，但对于细菌培养阴性者仍有重要意义。
