Edwardsiella tarda was isolated from 47, 88, and 79% of skin, visceral, and dressed-fish samples, respectively. This species was also isolated from 30% of imported dressed fish, 75% of catfish pond water samples, 64% of catfish pond mud samples, and 100% of frogs, turtles, and crayfish from catfish ponds. The incidence of Edwardsiella increased during the summer months, as water temperatures increased. Of several isolation media evaluated, the most effective was selective enrichment in double-strength Salmonella-Shigella broth and subsequent plating on single-strength Samonella-Shigella agar. The significance of the incidence of Edwardsiella in catfish, catfish disease, and public health could not be substantiated.
迟钝爱德华氏菌分别从47%的皮肤样本、88%的内脏样本和79%的去内脏鱼样本中分离得到。该菌种还从30%的进口去内脏鱼、75%的鲶鱼塘水样、64%的鲶鱼塘泥样本以及鲶鱼塘中100%的青蛙、乌龟和小龙虾中分离得到。随着水温升高，夏季几个月里迟钝爱德华氏菌的发生率有所增加。在评估的几种分离培养基中，最有效的是在双倍浓度的沙门氏菌-志贺氏菌肉汤中进行选择性富集，随后接种于单倍浓度的沙门氏菌-志贺氏菌琼脂平板上。鲶鱼中迟钝爱德华氏菌发生率、鲶鱼疾病以及公共卫生方面的意义尚未得到证实。
