Survival of the fish pathogen Aeromonas salmonicida in seawater.
Survival of Aeromonas salmonicida in natural (non-sterile) seawater, as determined from colony counts on marine agar, was found to be influenced by the presence of potentially inhibitory organisms, i.e., Acinetobacter, Aeromonas hydrophila, Chromobacterium, Escherichia coli, Flavobacterium and Pseudomonas, and their metabolites. Yet, samples, thought to be devoid of culturable A. salmonicida, were found to contain cells, which were filterable through 0.22 and 0.45 microns Millipore Millex porosity filters, and were recoverable on a specialised medium for L-forms, i.e. L-F medium.
