【摘要】 从海南省文昌县某养殖场患病方斑东风螺(Babylonia areolata)的吻、肌肉和肝脏中分离到2株优势菌。人工感染证实其中1株为致病菌,经形态学检测和生化鉴定,该病原菌为鳗弧菌生物变种Ⅰ(Vibrio anguillarum BiovarⅠ)。该病原菌对方斑东风螺的LD50值为1.7×10~6 cfu/g。药敏试验表明派拉西林、罗红霉素、红霉素、洁霉素、氟哌酸、先锋必、妥布霉素、菌必治、复方新诺明、利福平、复达欣、呋喃妥因等12种抗生素类药物对该病原菌敏感。更多还原

【Abstract】 Two dominant bacterial strains were isolated from the proboscis, muscle and liver of sick Babylonia areolata from a farm at Wengchang, Hainan. One of the stains was confirmed to be a bacterial pathogen of B. areolata by artificial infection and was determined to be Vibrio anguillarum BiovarⅠBased on morphological detection and biochemical tests. The LD50 of the pathogen to B. areolata was 1.7×10~6 cfu/g. Antibiotic sensitivity analysis indicated that the pathoge was sensitive to piperacillin, roxithromycin, cefobid, tobramycin, ceftriaxone, compound sulfamethoxazole,rifampicin, fortum and nitrofurantoin.更多还原
