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。
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.
