[Quantitative analysis of dominating intestinal flora among groups of people with different body fat].
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.


CONCLUSIONS
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.
