Studies on the Isolation of Vibrio vulnificus from Sea Water and Marine Products in the Southern Sea of Korea

한국 남해안 일대의 해수 및 해산물에서 Vibrio vulnificus의 분리연구

Authors studies on the isolation of V. vulnificus from sea water, sea mud fishes, shellfishes and algae at the seasides of Pusan, Masan, Chungmu and Ulsan in Korea in 1985. Authors carried out test for isolated strains to bacteriological test, hemolysis test about erythrocytes of various animal, sensitivity test of various chemotherapeutic agents and serological test with antiserum of V. vulnificus. The resultls obtained were as follows: 1. V. vulnificus was isolated 15 strains from 399 total specimens: 110 cases of sea water, 40 cases of sea mud, 90 cases of fishes, 60 cases of shellfishes and 79 cases of various algae, respectively. 2. Nine strains were isolalted from sea water, 4 strains were isolated from sea mud and 2 strains were isolated from fishes, respectively. 3. Two strains among 15 strains isolated were lactose positive reaction. 4. All strains isolated were grown in concentration of $0.5%{\sim}7.0%$ NaCl, but were not grown 0% and 8.0% NaCl. 5. Hemolysis reaction about various erythrocytes was sensitived to guinea pig, human and rabbit erythrocytes, but was not sensitived to sheep erythrocytes. 6. Sensitivity test using with chemotherapeutic agents of "BioLab" Microbial Sensitivity Test Discs were generally sensitived to amikacin, ampicillin, clindamycin, erythromycin, gentamycin, kanamycin, streptomycin, tetracyclin and tobramycin, and were moderate to penicillin, but were resistant to methicillin and lincomycin, respectively. 7. The distribution of serotypes of V. vulnificus isolated were on antiserum of $0.1{\sim}07$ of V. vulnificus: 1 case of 01 and 2 cases of 07, respectively.
