用BgATCC-47A-1纯培养物接种兔耳和背部皮下,造成急性感染、炎症反应。实验证实Bg是一株能引起组织损害的可疑病源菌。早期光镜下可见急性炎症反应组织像,许多细菌已被白细胞吞噬。晚期巨噬细胞增多,胞浆内亦有被吞噬的细菌。电镜下细菌位于细胞间隙或巨噬细胞胞浆内,可见吞饮泡,其内细菌有的形态基本完整,有的边界模糊。 Rabbit ears and back were inoculated subcutaneously with BgATCC-47A-1 pure culture, causing acute infection and inflammatory reaction. Experiments confirmed that Bg is a suspicious pathogen that can cause tissue damage. Early light microscopy shows acute inflammatory response tissue, many bacteria have been phagocytosed by leukocytes. Advanced macrophages increased cytoplasm also have been phagocytized bacteria. Bacteria under the electron microscope located in the cytoplasm of the intercellular space or macrophages, swallowing can be seen in the bubble, some of its internal bacteria morphology is complete, and some fuzzy boundaries.
