Abstract

This study was conducted to investigate the effects of environmental factor such as temperature, salinity, turbidity, pH and dissolved oxygen on the growth of Vibrio spp.. In this survey, total 56 seawater samples were obtained from 8 different sites of the Incheon coastal area during the periods from april 2008 to october 2008. Enumeration of Vibrio spp. was determined by using the most probable number(MPN) procedure. Isolation rates of V. parahaemolyticus, V. vulnificus, V. cholerae in all samples tested were 44.0%, 21.4% and 13.1%, respectively. The enumeration of Vibrio spp. was very low correlated with water temperature and pH and negatively correlated with salinity, dissolved oxygen and turbidity. We found salinity to be the parameter most highly correlated with the enumeration of Vibrio spp. The highest rate of antibiotic resistance of V. vulnificus and V.parahaemolyticus was Cefazolin(11.5%), Ampicillin(70.8%), respectively.
