藏獒魏氏梭菌病的诊断与防治

The diagnosis and prevention of Tibetan mastiff's Clostridium welchii disease

对疑似魏氏梭菌病的藏獒进行临床检查、病理剖检,无菌采取病料进行触片染色镜检、细菌分离、培养和生化试验,结果表明,该藏獒因长期采食未经加热处理的、冷冻保存的死猪肉而发病,临床出现精神沉郁,流涎、呕血、排煤焦油样的稀便后很快死亡;剖检内脏器官出现不同程度的出血、坏死,严重出血性肠炎;并分离出一株两端顿圆粗大平直的致病性梭状杆菌,确诊为藏獒魏氏梭菌病。

In order to provide a simple and practical method to the diagnosis and prevention for dogs which are infected with Clostridium welchii,the Tibetan mastiff suspected risk of Clostridium welchii disease were tested through clinical examination,pathological anatomy,and took sterile disease materials,contacted staining,bacterial isolation,culture and biochemical tests.The Tibetan mastiff＇s clinical symptoms,such as ademosyne,dribble,haematemesis,the loose stools look like coal tar and quickly died,because they foraged long-term the pork which was not heat-treatmented and cryopreservation.The pathological anatomy showed that the internal organs were hemorrhage and necrosis,besides there was hemorrhagic enteritis severity.Because the pathogenicity spindle rod was isolated,final diagnosis proved that the pathogenicity disease was Clostridium welchii.
