本文作者研究与O139有交叉反应的弧菌,其目的一是要证明为O139提供rfb基因的弧菌,二是要确保O139单克隆血清、多克隆血清诊断腹泻的特异性。作者筛选200株模拟弧菌,其中一株来源于池溏水,命名为N-57。通过玻片凝集证明N-57与O139多克隆抗血清(仅用霍乱弧菌CA385吸收)凝集,与O139诊断血清(用霍乱弧菌CA385、O22、O155吸收)不凝集, The aim of this study is to demonstrate that a Vibrio with rfb gene is provided for O139 and that the specificity of O139 monoclonal and polyclonal sera to diagnose diarrhea should be ensured. The authors screened 200 strains of Vibrio simiarum, one of which was derived from pool water and named N-57. Agglutination of the N-57 and O139 polyclonal antisera (only with Vibrio cholerae CA385) was confirmed by slide agglutination and did not aggregate with the O139 diagnostic serum (absorbed with V. cholerae CA385, O22, O155)
