1980年和1981年静冈县鳗鱼养殖池现场调查采集迟缓爱德华氏菌445株，其中270株（61%）经O凝集试验分为4个血清型（A、B、C、D）。以下3种样品血清型组成无较大差异；鳗鱼直肠含量、鳗鱼池塘水和池塘沉积物（A：13-17％，B：22-35％，C：4-13％，D：2-4％）。然而，肾脏样本中以A血清型为主（A：72%，B：0%，C：3%，D：13%）。通过对鳗鱼、罗非鱼和泥鳅的实验感染，与其他测试的血清型相比，E. tarda A血清型对鱼类，特别是鳗鱼具有高毒力。
Four hundred and forty five isolates of Edwardsiella tarda were collected on field surveys in eel culture ponds in Shizuoka Prefecture in 1980 and 1981. Two hundred and seventy isolates (61%) were classified, according to O-agglutination test, into four serotypes (A, B, C and D).There were no great differences in the composition of the serotypes among the following three kinds of samples; rectum contents of eel, eel pond water and pond sediments (A: 13-17%, B: 22 35%, C: 4-13%, D: 2-4%). However, serotype A was predominant in kidney samples (A: 72%, B: 0%, C: 3%, D: 13%).By experimental infection to eel, tilapia and loach, serotype A of E. tarda proved highly virulent to the fishes, especially to eel, in comparison with the other serotypes tested.
