摘要: 目的制备并标化16种实验动物相关病原菌鉴别诊断血清。方法将16种标准菌株灭活,制成适宜浓度的免疫用细菌菌液,分别经耳缘静脉和背部皮下多点注射32只SPF家兔,获得相应抗血清,经吸收去除非特异性凝集,制成特异性诊断血清。结果以玻片法和定量凝集法进行敏感性及特异性试验,结果显示抗血清只与相应的免疫用细菌形成特异性的凝集颗粒,抗血清凝集效价≥1∶1 280。结论所制备的抗血清特异性强、效价高,为实验动物细菌学检测提供了有效的血清学鉴别诊断试剂。

Abstract: Objective To prepare and standardize diagnostic serum which can be used to detect pathogenic bacteria in laboratory animals.Methods Thirty-two SPF rabbits were immunized with sixteen reference strains through intravenous and subcutaneous injections.All rabbits were immunized for five times with 5.0×10~(-8)~10×10~8/mL suspension made of inactivate reference strains after 18~24h culture in 37℃.The titers of antiserum were tested with bacteria agglutination.Results The antisera passessed a high efficiency of agglutination titers.The antisera had no cross-reaction with other reference strains and with a good specificity.Conclusion The antisera produced in this study would provide the useful diagnostic reagents for detecting pathogenic bacteria in laboratory animals.
