  • In this study, the ${\beta}$-lactamase (VPA0477) gene was used as a new target for the PCR-based detection of Vibrio parahaemolyticus. Primers specific for the ${\beta}$-lactamase (VPA0477) gene of V. parahaemolyticus, were designed and incorporated into a PCR-based assay. The assay was able to specifically detect all of the 191 V. parahaemolyticus strains tested, but did not result in amplification of 39 other Vibrio spp. and non-Vibrio spp. strains tested. The detection limit of the assay was 10 CFU of V. parahaemolyticus RIMD2210633 from pure culture broth. The ${\beta}$-lactamase (VPA0477) gene-based assay developed in this study was sensitive and specific, and has great potential for the accurate detection and identification of V. parahaemolyticus in seawater or seafood samples.

  • This study was carried out to investigate the distribution of Vibrio parahaemolyticus in the Incheon adjacent sea, and antimicrobial effect on growth of Vibrio parahaemolyticus in lactic acid and hydrogen peroxide and combination of lactic acid and hydrogen peroxide. The detected strains were compared geographical, months and sample types. The distribution of Vibrio parahaemolyticus was high at Ganghwa county with 66.1%(336 samples), on 7-9 months with 72.4%(386 samples) and from tireland with 75.0%(90 samples), respectively. The minimun inhibitory concentration (MIC) of lactic acid in Vibrio parahaemolyticus were 1250 ppm at pH 6.5 and 7.0, 625 ppm at pH 6.0. respectively. The minimun inhibitory concentration (MIC) of hydrogen peroxide in Vibrio parahaemolyticus were 25 ppm at pH 6.5 and 7.0, 12.5 ppm at pH 6.0, respectively. MICs of combined treatment of lactic acid and hydrogen peroxide in Vibrio parahaemolyticus were 625 ppm of lactic acid with 12.5 ppm of hydrogen peroxide. The correlations between MICs of lactic acid and hydrogen peroxide in Vibrio parahaemolyticus were obtained through the coefficient of determination($R^2$). $R^2$ value were 1.0000. The antimicrobial effect of lactic acid and hydrogen peroxide in Vibrio parahaemolyticus could be confirmed from the result of this experiment.

  • To investigate the distribution of Vibrio parahaemopyticus in the southern 4 coastal areas, Vibrio parahaemolyticus was isolated from seawater, shellfish and sediment from May to October in 1991, and antimicrobial effect of grapefruit seed extract (GFSE) on the growth of isolated strains were examined. In the 120 sample from 4 coastal areas, 16 strains of Vibrio parahaemolyticus were isolated and identified. The distribution serotype of isolated strains was 10 types of monovalent k-antiserum. Especially k-5 and k-28 were highly distribyted with 3 and 4 strains. 31.3% of isolated strains showed positive on Kanagawa phenomenon test. All isolated Vibrio parahaemolyticus were sensitive to chloramphenicol and gentamycin, 5 and 6 strains were resistant to streptomycin and colistin, respectively. Isolated strains were compared with geographical, month and sample. The distribution of 16 isolated Vibrio parahamolyticus was high at Hadong with 50%(8 strains), on July with 43.8%(7 strains) and from seawater with 37.5%(6 strains) respectively. Minimal inhibitory level of GFSE to Vibrio parahaemolyticus was 50 ppm. With 100 ppm treatment of GFSE, the destroy of cell membrane function, outflow of cell ingredients and ghost morphology of cell were investigated.

  • In the case of being contaminated with pathogenic Vibrio, shellfish pose a serious threat for public health. This study was conducted to investigate the presence of Vibrio parahaemolyticus and V. vulnificus in the seawater, bottom deposit and shellfish samples collected from the Gomso Bay, west coast of Korea. V. parahaemolyticus (30-80 CFU/g) was detected from seawater Jul. to Oct. and highest at Sep. V. parahaemolyticus was detected less than 10 CFU/g from seawater at Nov. with $14.6^{\circ}C$ of seawater temperature. V. parahaemolyticus (180-1,850 CFU/g) was detected more than 100 CFU/g from 3 kinds of shellfish, Short-necked clam Ruditapes philippinarum, Corb shell Cyclina sinensis, and Surf clam Mactra veneriformis, Jul. to Oct. and was highest in Surf clam at Oct. V. parahaemolyticus was detected less than 20 CFU/g from all tested shellfish at Nov. V. vulnificus (1.8-2.7 MPN/100 mL) was detected from seawater Jul. to Oct. and was not detected at Nov. V. vulnificus (18-236.7 MPN/100 g) was also detected from 3 kinds of shellfish Jul. to Oct. and was highest in Corb shell at Jul. V. vulnificus was not detected from all tested shellfish at Nov.

  • The naturally occurring plasmids of Vibrio species have been isolated in part to investigate their genetic traits. Among six different Vibrio species tested, Vibrio anguillarum, Vibrio fluvialis, Vibrio vulnficus, Vibrio mimicus and Vibrio furnissi did not show any presence of plasmid. One environmental isolate of Vibrio parahaemolyticus harboring plasmid was observed. The isolated plasmid was 8.7 kb by analysis with restriction endonuclease digestion. No common feature was shown relationships between the presence of plasmid and resistance against commonly used antibiotic compounds from the tested Vibrios.

  • 산초는 우리나라를 비롯한 일본, 중국 등지 에 널리 분포하고 있으며 전통적으로 우리 정서에 친숙한 식미와 향기를 가지는 아시아권의 공통적인 향신료이다. 더불어 우리나라에서는 생선회와 어패류의 소비가 증가함에 따라 Vibrio parahaemolyticus에 의한 식중독발생 억제방안의 확립이 필요한 실정이다. 따라서 본 연구는 독성이 없는 새로운 천연 식품 보존제의 개발을 위하여 식품 및 향신료로서 적용 범위가 광범위한 산초를 대상으로 Vibrio parahaemolyticus에 대한 천연항균제의 적용 가능성을 검토하였다. 산초나무 추출물의 항균작용을 알아보기 위해서 Vibrio parahaemolyticus에 대한 항균력 분석에서 종자를 제외한 성분으로 제조한 산초의 주정추출물이 효과가 가장 우수함을 확인하였으며, 이 추출물의 온도 및 pH에 대한 안정성을 검토한 결과 다양한 범위의 온도, pH에 대해서 매우 안정하다는 것을 알 수 있었다. 또한 GC-MS에 의한 산초 추출물의 분리, 동정 결과에서는 estragole이 항균활성을 나타내는 주성분임을 확인하였다. 이 결과를 바탕으로 우리나라에서 많이 사용되는 산초를 Vibrio parahaemolyticus에 의한 식중독을 줄일 수 있는 항균제로 적용할 수 있음을 확인할 수 있었다. 따라서 식품첨가제 및 포장재, 식품포장 외부 충진 물질, 살균소독제 등의 다양한 형태로의 응용이 가능하리라 생각된다.
