We isolated and characterized Escherichia coli (E. coli) from oyster Crassostrea gigas and inland pollution sources on
Yongnam-Gwangdo island and neighboring areas on the southern coast of Korea in 2014-2015. A total of 222 strains
of E. coli were isolated from 132 oysters and 88 samples from inland pollution sources. These 222 isolates were
tested for their susceptibility to 24 antimicrobial agents, and 221 isolates were found resistant to the tested antibiotics.
Of these 99.5% and 70.7% of the isolates showed very high resistance to rifampin and cephalothin respectively, followed
by tobramycin (23.4%), streptomycin (20.2%), tetracycline (19.4%), cefepime (18.9%), ceftazidime (18.9%)
and nalidixic acid (16.7%). The resistance rate of E. coli isolated from oysters was higher than that from inland pollution
sources. In addition, multiple resistance to at least four antibiotics were present in 73.2% and 26.5% of E. coli
isolates from oysters and inland pollution source samples, respectively.
