Spatiotemporal dynamics of the total and active Vibrio spp. populations throughout the Changjiang estuary in China.

ABSTRACT: Vibrio is ubiquitously distributed in marine environments and is the most extensively characterized group within Gammaproteobacteria. Studies have investigated Vibrio spp. worldwide, but mostly focused on pathogenic vibrios and based on cultivation methods. Here, using a combination of molecular and culturing methods, we investigated the dynamics of the total and active Vibrio spp. throughout the Changjiang estuary in China. The total Vibrio abundance was higher in summer (~6.59 × 10³ copies ml^-1) than in winter (~1.85 × 10³ copies ml^-1) and increased from freshwater to saltwater (e.g. 8.04 × 10¹ to 9.39 × 10³ copies ml^-1 in summer). The ratio of active to total Vibrio (Va/Vt) revealed a high activity of vibrios,
