title: Protection of rainbow trout (Oncorhynchus mykiss) from lactococcosis by probiotic bacteria.
abstract: We analysed the effect of probiotic supplementation on the control of lactococcosis in rainbow trout. Probiotic strains Leuconostoc mesenteroides CLFP 196 and Lactobacillus plantarum CLFP 238 were administered orally to fish for 30 days at 10(7) CFU g(-1) feed. Thirty days after the start of the probiotic feeding, fish were challenged with Lactococcus garvieae. Probiotic supplementation reduced fish mortality significantly, from 78% in the control group to 46-54% in the probiotic groups.
