1993年闽南漳州地区大面积推广牛蛙养殖。在7—9月份的高温季节,很多牛蛙场都暴发了以牛蛙红腿和皮肤溃疡为主要特征的传染病。该病传染快,发病率和死亡率高,给牛蛙养殖场带来巨大的经济损失。 我们在发病季节从蛙场采集、分离鉴定到该病的主要病原菌为嗜水气单胞菌(Aeromonas hydrophila)。该菌对氯霉素、庆大霉素高敏(抑菌圈≥15mm),对卡那霉素、利福平、红霉素中敏(15mm>抑菌圈≥10mm),对土霉素、四环素、青霉素、强力霉素、痢特灵不敏感。
In 1993, large-scale promotion of bullfrog breeding in Zhangzhou, southern Fujian. In the hot season of July-September, many bullfrog farms have outbreaks of infectious diseases characterized mainly by bull legs and skin ulcers. The disease is contagious, with high morbidity and mortality rates, which can cause enormous economic losses to the bullfrog farms. We collected from the frog field in the season of onset, and the main pathogen isolated and identified was Aeromonas hydrophila. The bacteria on chloramphenicol, gentamicin high sensitivity (inhibition zone ≥ 15mm), kanamycin, rifampicin, erythromycin sensitive (15mm> inhibition zone ≥ 10mm), oxytetracycline, Tetracycline, penicillin, doxycycline, furazolidone insensitive.
