Effect of Fed by Dietary Restriction on Evolution (Growth) of Intestinal Microflora in Rat
Öz
This study was conducted to evaluate the effect of the long-term dietary restriction applied to rat on counts of lactobacilli, coliform bacteria, enterococci and Enterobactericeae which are intestinal microflora mem-bers. For this purpose, rats vere divided to two groups. While the first group of rats were administrated dietary restrictions during 150 days, second group rats were control group and were fed by ad libitum. For both group, faeces samples of rats were collected at 1st, 30th, 60th, 90th, 120th and 150th days and microbiological analysis were performed. According to analysis results, lactobacillus, coliform bacteria enterococci and Enterobactericeae counts in the faeces of rats who was applied dietary restriction showed the a 1 log10 increase in the end of the 150th day while enterococci counts were determined in the same level. A statistically significant difference (p=0.02) was only observed in the counts of lactobacillus having probiotic properties in dietary restricted group. While a 2 log10 decrease in only enterococci counts in control group was observed, any change in counts of other bacterial groups was not detected. Statistical comparison between groups showed that coliform bacteria and Enterobactericeae counts were statistically different (p<0.05), while lactobacillus and enterococci counts were not statistically significant (p>0.05). As a result of this study, it was determined that the long-term dietary restriction in rat model has potential to change intestinal microflora.
