败血症是一种在家禽屠宰场进行宰后检查时根据肉眼可见的病变诊断出的不健康状况。败血症的早期识别具有重要的公共卫生意义。在这项研究中，多杀性巴氏杆菌，大肠杆菌，金黄色葡萄球菌败血症诱导肉鸡，以确定急性败血症的病变是否可以在骨骼肌的变化发展之前，在肉鸡尸体的内脏器官大体检测。在败血症急性期观察到脾脏和肝脏重量增加。在急性期观察到气囊炎、心包炎和肝周炎。和关节炎是S.金黄色葡萄球菌引起的败血症这些肉眼可见的病变足以在尸体骨骼肌发生变化之前识别出不健康的败血症肉鸡尸体。
Septicemia is an unwholesome condition diagnosed during postmortem inspection in poultry slaughter establishments on the basis of macroscopic lesions. Early identification of septicemia has important public health implications. In this study, Pasteurella multocida, Escherichia coli, and Staphylococcus aureus septicemia were induced in broilers in order to determine if lesions of acute septicemia can be grossly detected in the visceral organs of broiler carcasses prior to the development of changes in the skeletal muscle. Increased spleen and liver weights were observed during the acute phase of septicemia. Airsacculitis, pericarditis, and perihepatitis were observed during the acute phase of P. multocida- and E. roll-induced septicemia; and arthritis was the earliest indicator of S. aureus-induced septicemia. These macroscopic lesions were sufficient to identify unwholesome septicemic broiler carcasses prior to the development of changes in the skeletal muscle of the carcass.
