Abstract

Abstract

The diversity and distribution of vibrios in Shenzhen coastal waters were studied, and the relationships between environmental factors and vibrio quantity were investigated. Results showed that the seasonal variations of culturable vibrios in Shenzhen coastal sea seemed to be obvious. In the east costal sea, the number of marine vibrios in April(with an average value of 1.50×10⁴ CFU/cm³) was higher than that in September(with an average value of 8.89×10² CFU/cm³), while in the west costal sea, the number of marine vibrios in September(with an average value of 5.09×10² CFU/cm³) was higher than that in April(with an average value of 2.66×10² CFU/cm³). The highest number was detected in the Daya Bay. The seasonal variations of each dominant Vibrio sp. in the coastal waters indicate that V. gigantis-like species and V. splendidus-like species were dominant in April with lower temperature, while V. natriegens-like species were dominant in September with higher temperature; V. alginolyticus-like species were the dominant group in both seasons, the average number of it in April are higher than that in September. The vibrios density showed certain relationship between temperature, salinity, pH, level of fecal coliforms, level of total bacteria and culturable bacteria, and the salinity controls the distribution of vibrios obviously.
