Abstract / Zusammenfassung

The occurrence of potentially pathogenic Vibrio (V.) species at coastal bathing areas of the German North and Baltic Sea steadily rising causing global warming. Due to those facts, the risk of Vibrio infections, especially wound infections, associated with recreational bathing in European coastal waters for visitors and residents increase.
To get an overview, this study monitors the seasonal and spatial distribution of V. cholera, V. parahaemolyticus and V. vulnificus at seven recreational bathing areas over one-year period starting in June 2017.
V. parahaemolyticus was found as dominant Vibrio species during all seasons round the study areas of the North Sea. In contrast, V. vulnificus was found as dominant Vibrio species during all seasons round the study areas of the Baltic Sea. Therefore, the salinity influence the Vibrio spp. composition, whereas the water temperature is the most important determinant to detect Vibrio spp. from the sampling areas. An explosive increase begins around about then degrease water temperature reaching the highest detection rates during the summer months until 104 KBE/100ml water and 106 KBE/100g sediment and decrease rapidly during the winter month. In sediments Vibrio spp. concentrations were up to three log higher than in water and were detected through the winter months indicating an important role for Vibrio ecology (VBNC).
The high detection rates of potentially pathogenic Vibrio spp. during the summer month should be regarded with care.
