- Vibrio species isolated from various marine enviromments during the period form April to SEptember 1989 in the East sea and the South sea of Korea were studied for species distribution and antibiotiv suseptibility test in vitro. The number of strains isolated were 221 among 324 total specimens, they were classified into V. parahaemolyticus (27.6%), V. alginloyticus (51.6%) and nonfermenting Vibrio species (20.8%), but V. choerae and V. vulnificus were not isolated. V. parahemolyticus were more frequently isolated from Kyungju gun (31.7%) among 41 specimens by regional groups an followed by Geojegun (26.7%) and Masan city (26.3%), and shellfish (8 among 28 specimens; 28.6%) were showed the higher isolation rate among specimens tested. V. alginolyticus were more frequentiy isolated from Kyungju gun (45.2%), and sea water (75 among 166 specimens) showed higher isolation rate than tee other specimens. Nonfermenting Vibrio species were more frequently isolated from Masan city than the other regions, and sea water (10 among 19 specimens;; 24.7%) showed higher isolation rate of this strains. During the period of this study, the increased temperature of sea witer was found to be a correlatioin with the increased frequency of isolation rate of Vibrio species. Among V. parahaemolyticus, all strains were rresistant to penicillin and ampicillin, 68.9% to carbenicillin, and only 3.3% to cephalothin, but no resistant strains to other drugs tested were found. MICs of cephalothin to most strains were 16-32㎍/㎖, thus the resistance criteria to this drug was not deremined.
