Popis:	Edwardsiella ictaluri were found to develop and transfer plasmid-mediated antimicrobial resistance. All isolates tested were found to receive resistance(R)-plasmids at frequencies ranging from 10−3 to 10−6. The antimicrobials to which E. ictaluri became resistant included tetracycline and Romet, the only two antibiotics cleared for use in channel catfish (Ictalurus punctatus) culture. The frequency of plasmid transfer appeared to be temperature related, with higher frequencies at 30 °C than at 20 or 37 °C. E. ictaluri having received an R-plasmid was shown to transfer the plasmid to Escherichia coli and Yersinia ruckeri at fairly high frequencies.
