occurrence
showed a strong relationship to water temperature, as temperatures
above 20 ◦C promote growth of V. vulnificus. In sediments,
however, V. vulnificus remained culturable during the whole year,
presumably owing to favourable nutrient conditions. Non-O1/nonO139
V. cholerae were detected at all Baltic Sea sampling sites as
well and were found to be omnipresent during the whole year (in
the sediment also in January) (Brennholt et al., 2014).
