Abstract

We found viable non-culturable (VNC) Vibrio cholerae O1 attached to the cell envelope of the dinoflagellate Noctiluca scintillans. The significance of this find lies in the fact that N. scintillans could be a reservoir organism of VNC forms of V. cholerae in inter-epidemic periods, particularly when the extensive geographical distribution and the frequently high abundance of this dinoflagellate in marine environments is taken into account.
