Objective:
To investigate the alteration of dominating intestinal floras among groups of people with different body fat and probe into the possible effect on lipid metabolism.
Methods:
According to the BMI values, subjects were divided into 4 groups, including fleshless group, normal group, overweight group and obese group. Five dominating floras of all fresh stools were quantitated using selective culture method, and all data were analyzed statistically.
Results:
With the increase of BMI values, there is a decreasing trend in the amount of Lactobacillus, Bifidobacterium and Enterobacillus, and the amounts of Bacteriodes obviously increased (P < 0.01). No obvious alternation of the amounts of Enterococcus and Clostridium was observed.
Conclusion:
Bacteriodes may exert an boosting effect on the pile of fat and development of obese, however Enterobacillus, Lactobacillus, and Bifidobacterium have a potential opposite effect.
