A recombinant fimbrial protein of Edwardsiella tarda was designed to detect the specific antibody in Japanese flounder Paralichthys olivaceus. The specific antibody was detected from the fish intraperitoneally injected with E. tarda expressing the fimbria on LB agar containing 3% NaCl, but not from those injected with E. tarda without the fimbria, Streptococcus iniae, S. parauberis or viral hemorrhagic septicemia virus. In a flounder farm suffered with edwardsiellosis, the antibody-positive fish increased in ration with the occurrence of mortality. These results suggested that E. tarda with the fimbria was important for epidemics of edwardsiellosis at flounder farms.
