The Effects of Spirulina on Intestinal Microflora of Diarrhea Model Mice

Abstract:

The effects of Spirulina on intestinal microflora of diarrhea model mice were observed. Diarrhea model mice were geted by gastric perfusion ampicillin, then these mice were given different doses spirulina by gavage. Selective culture media were used to culture bifidobacteria, bacterium lacticum, enteric bacilli, enterococci, bacteroid, clostridium perfringens in feces at different times. In order to find the difference of collecting samples from feces and intestine, the quantity of detection flora in different segment of intestine were compared too. The result showed that in middle dose group and high dose group spirulina can regulate and improve intestinal flora of diarrhea model mice, and effectively shorten time from disturbance to balance. Fecal sample and intestinal contents sample both manifest a same trend, that is the quantity of bifidobacteria, bacterium lacticum in treatment recovery group is significantly higher than saline group, and enteric bacilli, enterococci, bacteroid, clostridium perfringens is significantly lower than saline group, but each index flora in intestinal contents sample has a significant difference in quantity.
