棘胸蛙体大肉鲜,有较高的食用和药用价值,是倍受市场青睐的养殖品种,目前随着人工养殖的发展,以及养殖密度的提高,引发的棘胸蛙疾病也愈来愈多,危害日益严重,直接影响养殖的经济效益。我县棘胸蛙仿生态养殖已遍布8个乡(镇)20个村80多户(场),养殖总面积达8561米2,年产商品蛙12.05吨的生产规模。针对这一状况,笔者于1998~1999年间,对我县棘胸蛙养殖的蛙病开展了大面积调查研究,并进行了棘胸蛙药物敏感试验,现将结果报告如下。1病害调查1.1调查范围及方法调查范围为全县7个重点养蛙乡镇、19个… 相似文献

自腹部肿大、腹水和出血等症状的患病棘胸蛙蝌蚪内脏中分离到4株细菌,人工感染确定菌株JK-3为致病菌。经生化鉴定,菌株JK-3符合肺炎克雷伯菌特征; 16S rDNA基因序列比对及系统发育分析表明,菌株JK-3与肺炎克雷伯菌标准株(ATCC700721/NR_074913.1)的同源性达99.5%。结果表明,菌株JK-3为肺炎克雷伯菌,是引起棘胸蛙蝌蚪腹部肿大、腹水和出血等症状疾病的病原。药敏试验结果显示,肺炎克雷伯菌JK-3对美满霉素、丁胺卡那、复达欣、哌拉西林、庆大霉素、先锋必素、先锋Ⅳ敏感,对其余19种药物均耐药或中度耐药。 相似文献

棘胸蛙烂皮病奇异变形杆菌的分离、鉴定及对药物敏感性研究 总被引:2,自引:0,他引:2
从患烂皮病的棘胸蛙(Rana spinosa)中分离到一株致病菌,通过形态学、生理生化试验等方法鉴定该致病菌株为奇异变形杆菌(Proteus mirabilis)。同时,通过抑菌圈法研究了该菌株对11种抗生素、11种中草药、4种消毒剂的敏感性。结果显示:该菌株对头孢曲松、阿莫西林、链霉素、诺氟沙星、庆大霉素、卡那霉素、氯霉素等抗生素敏感,对四环素、红霉素不敏感;未观察到黄芪、茵陈对该菌的抑制作用,忍冬藤抑菌效果最好,其次依次为紫花地丁、金银花与甘草、鱼腥草、大青叶与柴胡、陈皮、黄连;致病菌株对消毒剂的敏感性依次为:高锰酸钾﹥三氯异氰脲酸﹥硫酸铜﹥氧化钙。 相似文献

Five herbs such as Acalypha indica, Hygrophila spinosa, Picrorhiza kurooa, Tinospora cordifolia and Zingiber officinale were selected to screen for the in vitro immunostimulant activity against the shrimp pathogen Vibrio harveyi using different organic polar and non-polar solvents. After initial screening, the best extract of the five herbs was mixed thoroughly in equal proportion and made it an artificial immunostimulant diets (ISD) such as ISD-1(500), ISD-2 (1,000), ISD-3 (1,500) and ISD-4 (2,000) mg?kg?1. The control diet was prepared without adding immunostimulant herbal extracts. The Indian white shrimp, Fenneropenaeus indicus having the weight of 8.0?±?1.0?g, were fed with the above diets for 60?days. After the completion of feeding trail, they were challenged with V. harveyi at the rate of 107CFU/ml and found out the cumulative mortality, growth parameters, haematological and immunological parameters. The weight gain and specific growth rate were significantly (P?<?0.05) increased from the control group to experimental group. The immunostimulant active principles helped to decrease the coagulation time and improved the total haemocyte count (THC), phagocytosis, phenol oxidase (PO) activity, haemagglutinin activity and bacterial clearance. 相似文献
