【摘要】 呋喃那斯对暴发性鱼病的BSK-10菌株的最低抑制浓度(MIC)为0.019mg/L,比呋喃唑酮的用量低32倍。用0.2和0.5mg/L浸泡药浴病鱼的治愈率为90％和100％;50mg/L呋喃唑酮的治愈率为0.10mg/L和20mg/L药浴10分钟的死鱼时间比50mg/L呋喃唑酮迟1天。以0.5和4.0μg/g腹腔注射(ip)给药的防治效果也优于同剂量的呋喃唑酮。对鲢以100mg/L药浴2小时或白鲫ip600mg/kg,均未引起死亡或异常。更多还原

【Abstract】 The Minimal Inhibitory Concentration (MIC) of Furanace to bacteria strain BSK-10 separated from fish with acute epidemic septicemia, was 0.019mg/L, which was 32 times less than that of Furaxone. When infected fishes were immersed with Furanace at concentration of 0. 2mg/L and 0.5mg/L, the cure rates were 90% and 100%, respectively. But Furaxone was ineffective on infected fishes at concentration of 50mg/L. Infected fish in 10 or 20mg/L Furanace died one day later than that in 50mg/L Furaxone for 10 minutes bath, Furanace was more effective than Furaxone to Infected fish which was injected intraperitoneally (ip) at concentration of 0.5 and 4.0μg/g. Furanace was nontoxic to silver carp which was immersed for 2 hours at concentration of 100mg/L, it was also nontoxic to crucian carp which was injected ip at concentration of 600mg/kg.更多还原
