【摘要】 针对龙井市林蛙养殖场中出现的后腿肌肉变成红色、肝肿大呈紫红色、肾脏充血呈鲜红色心肌缺血性坏死为主要症状的患病林蛙,进行了细菌分离培养、生化试验、毒力检测、人工感染、药物敏感度等试验研究,结果证明引起该病的病原菌为嗜水气单胞菌。药敏试验结果表明,该病原菌对链霉素,诺氟沙星、庆大霉素等高度敏感,而对红霉素、青霉素等不敏感。更多还原

【Abstract】 The bacterial pathogens were isolated from the diseased wood frog ,which were cultured in a certain farm in Longjing county,Yanbian,Jilin province.The main symptom of diseased wood frog was that the muscle under hind-leg tur- ned red,the liver turned tumefy and appeared deep mauve,and the kidney congested and appeared fresh-red.Heart muscle ischemic necrosis. By the experiment of isolation , biochemical experiment,cultivationartificial infection,biochemical ex- periment and antibiotic sensitivity,the pathogens were identified as Aeromonas hydrophila.The results of antibiotic sensi- tivity tests showed that Streptomycin , Norfloxacin and Gentamycin were the most sensitive drugs and the pathogens were not sensitive to Erythromycin.更多还原
