Abstract
The distribution of Clostridium botulinum serotypes A, B, E and F in aquatic environments of the Baltic Sea and Finnish mainland was examined. A total of 110 samples were tested with a neurotoxin-specific PCR assay. Clostridium botulinum type E was found in 81% of sea and 61% of freshwater samples. No other toxinotypes were found. Spore counts were quantified by the most probable number method, Cl. botulinum type E kg(-1) averaging 940 in sea and 370 in freshwater samples. The overall prevalence and spore counts of Cl. botulinum type E in aquatic sediments correlated significantly with offshore bottom oxygen content, depth, and bioturbation activity, whereas there was no correlation with bottom water temperature. These findings indicate the possibility of Cl. botulinum type E multiplication or at least, suitable conditions for spore survival, in anoxic sediments.Entities:
