ABSTRACT: We analysed the influence of various bacteria on the in vitro growth of trophozoites of a Platyamoeba strain isolated from diseased gill tissues of cultured turbot. Little or no growth was shown by amoebae cultured in the presence
of (1) the turbot-pathogenic bacteria Vibrio anguillarum, Aeromonas salmonicida or Streptococcus sp., (2) Pasteurella piscicida or Vibrio vulnificus (pathogenic for some fishes but not turbot), or (3) the non-pathogenic
'environmental' bacteria Vibrio campbelli, Vibrio fluvialis or Pseudomonas dondorofii. The only bacteria which were successfully utilized as food sources were Aeromonas hydrophila (pathogenic for some fishes but not turbot) and
the non-pathogens Vibrio natriegens, Pseudomonas nautica and Escherichia coli. These results suggest that the colonization of the gills of cultured turbot by the epizoic amoeba Platyamoeba may be an indicator of faecal
contamination.
