常规试管凝集试验与虎红平板试验判断布氏杆菌病的比较

Comparison of conventional standard tube agglutination test and rose bengal precipitation test in determining brucellosis

目的:寻找一种快速、准确、敏感性强的试验方法诊断布氏杆菌病。方法:虎红平板凝集试验和试管凝集试验。结果:试管凝集试验阳性检出率为35.7%,虎红平板凝集试验阳性检出率为38.1%,阳性符合率为93.8%。虎红平板凝集试验的灵敏性较强。试管凝集试验有良好的特异性。结论:虎红平板凝集试验适用于对布氏杆菌病大范围的筛查及流行病学调查。

Objective： To explore a fast, accurate, sensitive test to diagnose brucellosis. Methods： The rose bengal precipitation test （RBPT） and standard tube agglutination test （SAT） were employed. Results： The positive rate of standard tube agglutination test was 35.7%, while that of rose bengal precipitation test was 38.1%, the positive coincidence rate was 93.8%. The rose bengal precipitation test had stronger sensitivity, while the standard tube agglutination test had a higher specificity. Conclusion： Rose bengal precipitation test is suitable for screening and epidemiological research in wide range of brucellosis.
