Temporal and spatial co-occurrence of pacific oyster mortality and increased planktonic Vibrio abundance
Summary: Oyster mortality and human food poisoning events are linked to pathogens from the Vibrio genus. However, the link between these events, planktonic bacterial dynamics and environmental variables has not yet been resolved. In Port Stephens, Australia, we characterized the microbial community...

| description | Summary: Oyster mortality and human food poisoning events are linked to pathogens from the Vibrio genus. However, the link between these events, planktonic bacterial dynamics and environmental variables has not yet been resolved. In Port Stephens, Australia, we characterized the microbial community and quantified the abundance of total Vibrio, Vibrio harveyi, and Vibrio parahaemolyticus in a (i) 27-month seawater planktonic microbial time-series; (ii) samples of Pacific oysters (Crassostrea gigas) during a mortality event and (iii) seawater samples following the mortality event. Vibrio harveyi and V. parahaemolyticus exhibited seasonal abundance, peaking during the summer months. Total Vibrio and V. harveyi in seawater were significantly greater at sites with high levels of oyster mortality and decreased 5-fold in the weeks following oyster mortality. Our findings provide evidence for the role of Vibrio in oyster mortality events and indicate that ocean warming and elevated phytoplankton may stimulate putative pathogens in the Vibrio genus. |
