A total of 423 shellfish (Oysters, Crassostrea gigas; short-necked clams, Ruditapes philippinarum and corb shells, Cyclina sinensis) were collected from the west coast of Korea, from which 277 Escherichia coli strains were isolated. The antimicrobial susceptibility patterns of isolated strains were analyzed for 22 antimicrobial agents used in Korea for clinical or veterinary therapy. The resistance of E. coli isolates to ampicillin (37.2%) was highest, followed by cephalothin (21.7%), cefazolin (19.9%), trimethoprim (15.2%). Antimicrobial resistance was present in 56.7% of E. coli isolates against at least one antimicrobial agent. Of 277 isolates, 44 (15.9%) were resistant to multiple antimicrobial agents.
