Inhibitory activity of antibiotic-producing marine bacteria against fish pathogens

Resumo
The activity of antibiotic-producing marine bacteria was assayed
against bacterial fish pathogens belonging to the genera Vibrio,
Aeromonas, Pasteurella, Edwardsiella, Yersinia and Pseudomonas
with the aim of evaluating the possible use of these marine strains
for controlling epizootics in aquaculture. Inhibition tests on solid
medium showed that, in general, the majority of fish bacteria were
strongly sensitive to the marine bacteria. Only two strains
(Edwardsiella tarda and Pseudomonas aeruginosa), were resistant to
all the antibiotic-producing strains. The results of antagonism assays
in sea water, however, varied according to the fish pathogensexamined.

Experiments conducted using cell-free supernatant fluids
of marine bacteria demonstrated the involvement of antibiotic
substances in the inhibition of fish pathogens.
