Abstract: Summary Sahandi, J., H. Jafaryan, P. Moradi & Ch. Tadiri, 2013. Effect of infeed probiotic blend on growth performance and infection resistance of the guppy ( Poecilia reticulata ). Bulg. J. Vet. Med. , 16, No 4, 243 −250. The present study was carried out to evaluate the dietary effects of Saccharomyces cerevisiae and Bacillus spore ( B. licheniformis and B. latrospore ) probiotic blend in guppy (Poecilia reticulata ) larvae 30 days after the first feeding at ratios of 0.5%, 1% and 1.5%. Bacillus spores were used with the same density of 1×10 9 cfu/100 g in all treatments. There were no significant differences in larvae growth performance (P>0.05). A significant effect was observed when fish were challenged with Ich- thyophtirius multifilus parasites (P<0.05). The highest survival percentage was observed in the group which received 1.5% yeast supplement and 1×10 9 cfu/100 g Bacillus spores. Also the highest mortal� ity was related to group D1 which was fed a diet containing 1% of Saccharomyces cerevisiae and Bacillus spore blend. This information indicates that the blend of Saccharomyces cerevisiae and Ba- cillus spore can act as immune stimulator to treat fish ectoparasites, Ichthyophtirius multifilus instead of chemical drugs.
