Abstract:
Saccharomyces cerevisiae (SC47) yeast has been used in the feeding of several domestic animal species and humans and symbiotic Kombucha tea (TK) has been used in humans, both as
alternative therapy and health-enhancing. The mechanisms of these effects are not known, and it is thought that might be associated with a modification of the intestinal flora. In this work, the effects of these probiotics on the fecal coliform populations isolated rabbit was evaluated. The experimental model was three groups of adult rabbits, without contact with probiotics. The Sc group which received 0.3% commercial SC47, the TK group received two ml / kg body weight of commercial TK: A stool sample from all animals in the experimental group on days 0, 7, 14 and 21 were taken; seed on selective media for coliform per g. of faeces; isolation, counting and identifying bacterial species was made using samples of the experimental days 0 and 21. The results showed that both probiotics increased faecal coliform populations (P <0.05). The culture supernatants of SC47 had no antimicrobial effect on the isolated bacterial genera. Kombucha supernatant had an inhibitory (P <0.05) effect on the genera E. coli, Plesiomona spp, Serratia spp, Salmonella spp, Yersinia spp, Acinetobacter, Pseudomonas spp, Actinobacillus spp, Moraxella spp, Alcaligenes spp, Pasteurella spp. Both probiotics modulated faecal coliform populations in rabbits by different mechanisms; antimicrobial and / or by competitive exclusion. Although it has been reported that some probiotics can modulate the intestinal microbiota by acidification of the medium, in this study no changes in pH were observed. Mechanisms of intestinal microbiota modulation induced by probiotics are poorly understood, so further studies are required.
