以分离大鲵感染的病原菌并进行菌株鉴定和药敏实验为目的,通过从患病大鲵的不同部位取样,分离培养到可疑菌落,然后进行鉴定和药敏试验。根据药敏试验结果指导养殖场进行治疗。结果鉴定为恶臭假单胞菌,中等大小、光滑、湿润的灰白色革兰氏阴性长杆菌,排列不规则。药敏试验证实对舒普深、诺氟沙星、呋喃妥因等敏感。 For the purpose of isolating the pathogen of Rana nigromaculata and isolating and detecting the strain, the samples were collected from different parts of Sick Owl and the suspicious colonies were isolated and cultured. Then the identification and drug susceptibility test were carried out. According to drug susceptibility test results guide the farm for treatment. Results identified as Pseudomonas putida, medium size, smooth, moist gray-white gram-negative bacteria, arranged irregularly. Susceptibility testing confirmed Shu Pu deep, norfloxacin, nitrofurantoin and other sensitive.
