摘要: 将布氏杆菌分不同剂量皮下注射接种于健康牛,于接种后45 d剖杀,采集相关的器官组织制备组织切片,应用免疫组化方法检查细菌在牛体内的分布。结果显示,肝脏、脾脏、肾脏、淋巴结出现强阳性信号;在高剂量注射的牛体内,肺脏、颌下淋巴结出现阳性细胞;心脏和健康牛组织呈阴性反应。阳性信号主要位于感染细胞的胞质中,偶尔出现在细胞核内。

Abstract: The healthy conventional cattles were inoculated subcutaneouly with different CFU of Brucella abortus strain, the cattles were necropsy on day post inoculation. Tissues were collected for preparing tissue sections and immunohistochemistry protocol was developed to detect distribution of B.abortus bacterium in tissue samples. Results showed that in liver, spleen, kidney and lymphoid tissues were positive for B.abortus antigen. Positive signals also presented in lung, mandibular lymph node. Other tissues such as heart and control were negative for antigen. B.abortus antigens were localized predominately in the cytoplasm of the infected cells and rarely observed in the nucleus of the cells.

Key words: Brucella abortus; immunohistochemical; positive signals
