Ga. Wooster et Pr. Bowser, THE AEROBIOLOGICAL PATHWAY OF A FISH PATHOGEN - SURVIVAL AND DISSEMINATION OF AEROMONAS-SALMONICIDA IN AEROSOLS AND ITS IMPLICATIONS IN FISH HEALTH MANAGEMENT, Journal of the World Aquaculture Society, 27(1), 1996, pp. 7-14
The aerobiological (aerosol) pathway of Aeromonas salmonicida subspeci
es salmonicida (ATCC 33658) was investigated, Results indicate that vi
able A, salmonicida can travel as an aerosol/droplet spray at least 10
4.1 cm (limits of the test chamber used) when carried by air currents.
Additionally, viable A. salmonicida was recovered from water exposed
to an experimentally generated aerosol/droplet spray of A. salmonicida
downwind from the contaminant source. It is possible that viable bact
erial aquatic animal pathogens can be spread via the airborne route, T
his possible route of pathogen introduction could effect current manag
ement or system designs, especially when aquaculture systems consist o
f tanks in close proximity.
