“…Microbial populations may release chemical substances that have a bactericidal or bacteriostatic effect on other microbial populations, which can alter interpopulation relationships by influencing the outcome of competition for chemicals or available energy (28,62,94). The presence of bacteria producing inhibitory substances in the intestine of the host, on its surface, or in its culture medium is thought to constitute a barrier against the proliferation of (opportunistic) pathogens.…”

“…In general, the antibacterial effect of bacteria is due to the following factors, either singly or in combination: production of antibiotics (145), bacteriocins (15,94,136), siderophores (which are dealt with in a later section), lysozymes, proteases, and/or hydrogen peroxide and the alteration of pH values by the production of organic acids (126). Vandenbergh (136) added the formation of ammonia and diacetyl to this list.…”

“…Pybus et al (94) tested thirty strains of V. anguillarum as potential probiotics against the salmon pathogen V. ordalii by the deferred-antagonism test. Only one strain (V. anguillarum VL4335) inhibited strains of V. ordalii in vitro, and this effect was blocked when iron salts were added to the medium, indicating that the growth inhibition was linked to iron deficiency.…”

SUMMARY There is an urgent need in aquaculture to develop microbial control strategies, since disease outbreaks are recognized as important constraints to aquaculture production and trade and since the development of antibiotic resistance has become a matter of growing concern. One of the alternatives to antimicrobials in disease control could be the use of probiotic bacteria as microbial control agents. This review describes the state of the art of probiotic research in the culture of fish, crustaceans, mollusks, and live food, with an evaluation of the results obtained so far. A new definition of probiotics, also applicable to aquatic environments, is proposed, and a detailed description is given of their possible modes of action, i.e., production of compounds that are inhibitory toward pathogens, competition with harmful microorganisms for nutrients and energy, competition with deleterious species for adhesion sites, enhancement of the immune response of the animal, improvement of water quality, and interaction with phytoplankton. A rationale is proposed for the multistep and multidisciplinary process required for the development of effective and safe probiotics for commercial application in aquaculture. Finally, directions for further research are discussed.

SUMMARYA total of 279 Vibrio anguillarum strains were serotyped and examined for plasmid content. Plasmids were subjected to digestion with restriction enzymes. Most strains belonged to serogroup 01 (39%) and 02 (16%). In total 164 strains (53%) carried plasmids. Of the 01 and 02 isolates, 92 % and 30%, respectively, carried one or more plasmids. Restriction fragment length polymorphism (RFLP) analysis of plasmid DNA indicated that plasmids belonged to several groups. Each group seemed to be restricted to a single 0-serovar. The largest group was the pJM1-like plasmids among most serovar 01 strains. Most of these plasmids were about 67 kb like the pJM1 plasmid, but various derivatives ranged from 26-77 kb. RFLP studies of the 67 kb plasmids revealed 17 different restriction patterns. Some patterns were dominant among European strains whereas others were dominant among North American strains. The results confirmed the applicability of 0-serotyping together with plasmid profile and restriction analysis of plasmids for typing of V. anguillarum. They also indicated that plasmids among strains which belonged to the traditional fish pathogenic serogroups, 01 and 02, showed more homology than did strains from most other serogroups, that were usually non-pathogenic, environmental bacteria.

New Zealand isolates of Vibrio anguillarum from water, sediments and healthy salmon were tested for their ability to grow under iron-limiting conditions and to produce siderophores. Their growth in the presence of the iron chelator ethylenediamine-di(o-hydroxyphenylacetic acid) (EDDA) suggested they could withstand conditions of iron limitation, with a 200 µM EDDA MIC recorded for the majority of strains. A positive reaction in the chrome azurol sulphate assay after growth in a low iron-containing medium, which was negated when the medium was supplemented with 10 µM iron, indicated they could produce siderophores. The siderophores were of the phenolate class and their biological activities indicated they were related to enterobactin.
