Abstract:

The authors investigate dynamic change regularity of Vibrio species in the Daya Bay using molecular identification method. Brine from different locations of the Daya Bay was cultured, purified and identified. A total of 368 Vibrio isolates were obtained from 224 seawater samples. Using molecular biology method following biochemical identification, they find Vibrio alginolyticus, V. parahaemolyticus, V. harveyi and V. vulnificus, but not V. cholerae, V. mimicus, V. vulnificus and V. hollisae in the brine from the Daya Bay. The results show that V. alginolyticus and V. parahaemolyticus are the dominant species, which occupy 27.99% and 21.74% of the overall Vibrio isolates, respectively.

Key words: Vibrio, molecular identification, species composition, the Daya Bay, seasonal distribution
