A rather wide variety of drug resistant gram-negative bacteria were isolated from the eel-pond water as well as from the intestinal tracts of cultured and wild eels (Anguilla japonica and Anguilla anguilla) in various districts. A fairly high proportion of the drug resistant bacteria isolated were found to carry R factors. Occurrence rate of R factor-carrying bacteria varied in different districts, being high in the Yaizu and Yoshida areas and low in the Hamana-Lake area and in wild eels. R factors were found in Aeromonas liquefaciens, Vibrio and Enterobacteriaceae strains but not in Achromobacter, Alcaligenes, Pseudomonas strains. The drug-resistance markers of the R factors were almost exclusively sulfonamides and tetracycline. This tendency was apparent particularly in A. liquefaciens.
