영문 초록

A total 41 strains of Edwardsiella tarda were isolated from cultured eels and examined for drug resistance, distribution and transferabilities of R plasmids. All isolates were multiple-resistant to drugs(at least 4 among 13 drugs) and mostly restricted to LM(41 strains), SD(41 strains), CH(39 strains), SF(38 strains), CP(37 strans), PM(37 strains), OT(36 strains), SM(29 strains), OA(29 strains), AM(28 strains), KM(7 strains), GM(6 strains), AK(6 strains) and EF(2 strains). Twentyfive different drug resistant patterns were observed, the most frequently encountered pattern was LM-SD-CH-SF-CP-PM-OT-SM-OA (8 strains, 20%) followed by LM-SD -CH-SF-CP-PM~SM-OA(5 strains, 12%). In transfer experiment. transferable R plasmids were carried in 39 of 41 resistant strains, indicating that most isolates carried conjugally transferable R plasmids related to multiple drugs. The most frequently observed transferable R plasmids were SD-SF-CP-CH-LM-PM-AM (4 strains), SD-CP-CH-LM-PM-AM-OT(3 strains), SD-SF-CP-CH-LM-PM(3 strains) and SD-SF(3 strains). These results suggest that the chemotherapy of edwardsiellosis is extremely difficult because of the acquirement of multi drug resistance to wide range of antibacterials. Futhermore it seems that high levels of various chemotherapeutjcs have already been introduced to eel culture.
