| Many recent papers have deepened the state of knowledge about lactic acid bacteria (LAB) in fish gut. In spite of high variability in fish microbiota, LAB are sometimes abundant in the intestine, notably in freshwater fish. Several strains of Streptococcus are pathogenic to fish. S. iniae and Lactococcus garvieae are major fish pathogens, against which commercial vaccines are available. Fortunately, most LAB are harmless, and some strains have been reported for beneficent effects on fish health. A major step forward of the recent years was those converging evidences that LAB can stimulate the immune system in fish. An open question is whether viability can affect immunostimulation. The issue is crucial to commercialise live probiotics rather than... |

| This minireview summarizes the present state of knowledge concerning the importance of yeasts in fish gut. Yeasts have been commonly isolated in the gastrointestinal tract, and high population densities were sometimes noted in healthy fish, but the data were quite variable in terms of colony counts and taxonomical diversity. Rhodotorula sp. seemed relatively frequent in both marine and freshwater fish, and Debaryomyces hansenii has been found to be dominant in rainbow trout. Some other dominant strains have been described, such as Metschnikowia zobelii, Trichosporon cutaneum, and Candida tropicalis in marine fish, and Candida sp., Saccharomyces cerevisiae, and Leucosporidium sp. in rainbow trout. The natural proliferation of yeasts in fish mucus may be... |
