| Abstract: |
| 目的为人畜布鲁氏菌病（布病）血清学诊断、监测及流行病学调查提供实用和简便的方法。方法在首次制备布鲁氏菌（布氏菌）抗原-辣根过氧化物酶结合物的基础上,建立了检测人畜布氏菌抗体的双抗原夹心酶免疫试验（DAgS-EIA,包括DAgS-ELISA及DAgS-DIEA）.用本法及间接ELISA（I-ELISA）、试管凝集试验（SAT）及虎红平板凝集试验（RBPT）等常规血清学方法对从河南省及河北省收集的部分布病患者、可疑患者,布氏菌感染羊只以及布氏菌感染的实验动物血清标本进行了检测。结果对布病患者及可疑者的检查结果表明,阳性率以DAgS-ELISA最高（60.0%～62.9%）,余依次为RBPT（48.6%～58.1%）、I-ELISA（55.6%）、DAgS-DIEA（53.7%）及SAT（44.2%）;对布氏菌感染羊的阳性率均为81.8%.结论 上述结果表明,双抗原夹心酶免疫试验检测人畜布氏菌抗体,不仅特异、简便而且仅制备一种布氏菌抗原-酶结合物就可对人及多种动物进行检测。 |

| ObjectiveIn order to develop practicable methods for serodiagnosis,surveillance and epidemiological surveys in human and animals Brucellosis.Methods A double antigens sandwic Enzyme Immunoassay (DAgS-EIA include DAgS-ELISA and DAgS-DIEA)have been developed under the basis of first production conjugate of Brucella antigen with horseradish peroxidase.Serum samplesfrom diagnosed patients,suspected patients of Brucellosis and sheep infected with Brucella in Henan and Hebei provinces as well as from experimental animals of infected w ith Brucella in laboratory detected through DAgS-EIA,I-ELISA,RBPT and SAT tests.Results Of the diagnosed and suspected Brucellosis patients, positive rates of DAgS-ELISA,RBPT,I-ELISA,DAgS-DIEA and SAT were 60.0%-62.9%,48.6%-58.1%,55.6%,53.7% and 44.2% respectively;as for sheep with Brucella infection,positive rate of the above mentioned 5 tests were 81.8%.Conclusion Results showed that DAgS-EIA were not only specific and practicable but may use for Brucella specific antibodies detection in humans and various animals with only one conjugate of Brucella antigen with horseradish peroxidase |
