摘  要:为了研究沙门菌感染雏鹅的主要病理组织学变化。采取腹腔注射沙门菌人工感染7日龄健康雏鹅,对发病雏鹅进行病理剖检,并采取肺脏、肝脏、脾脏和肠道病料制作病理切片,光学显微镜下进行病理组织学观察。受感染雏鹅剖检病变可见皮下、心肌、肺脏、脾脏、肠道、脑膜等多处出血,肝脏坏死,胆囊、脾脏肿大;显微病理组织学变化为肝、脾、肺、肠道等器官出血、细胞变性、坏死,有炎性细胞浸润。结果表明,感染沙门菌雏鹅出现了广泛性的组织损伤,同时伴随着机体各器官明显的炎症反应。To investigate the histopathology of goslings infected with salmonella,seven-day-old goslings with good conditions were intraperitoneally inoculated with 0.2 mL Salmonella.The pathological changes were observed with naked-eye after autopsy.Meanwhile,tissues of lungs,liver,spleen and intestines were prepared into paraffin sections,followed by histopathology observation under a microscope.The results showed that hemorrhage in subcutaneous,cardiac,lung,spleen,intestine and meninx,necrosis in liver,tumefaction of spleen and gallbladder in goslings.The histopathology under the microscope were hemorrhage,cell degeneration,necrosis and inflammatory infiltration in liver,spleen,lung and intestine.In conclusion,goslings infected with salmonella show extensive tissues damage,and significant inflammatory response in multiple organs.
