目的探讨不同BMI大学生群体部分肠道细菌数量差异。方法依据身高体重指数(BMI),于大学生群体中随机选择BMI≥24的16例(超重组),BMI≤18.5的11例(偏瘦组),18.5≤BMI≤24的19例(正常组),以此为研究对象,采集新鲜粪便,运用活菌计数法统计其需氧条件下在TSC、PS、EMB培养基上细菌的生长数量,比较三组间细菌生长数量差异。结果三种培养基上不同BMI组间细菌数量均存在差异,其中各组间进行两两比较,TSC培养基上,超重组和偏瘦组的细菌菌落数比正常体重组均有升高,但无统计学意义(跃0.05)；PS培养基上,偏瘦组比正常体重组细菌菌落数明显升高(<0.05)；EMB培养基上,偏瘦组比正常体重组和超重组的细菌菌落数量均明显升高,且随着体重指数的升高,有细菌数量明显下降的趋势。结论不同BMI大学生群体粪便中细菌数量构成存在差异。

Objective To investigate the quantity variance of segmental intestinal bacteria in undergraduate with dif erent BMI.Methods According to the Body Mass Index (BMI) criteria,Fecal samples were col ected from 16 students as BMI≥24(overweight group),11 students with BMI≤18.5 (lean group)and 19 students with 18.5≤BMI≤24(normal group).Bacteria which cultured by TSC、PS and EMB mediums respectively under aerobic condition were counted through live bacteria counting method.The quantity variances between groups were compared.Results Bacteria's number in three kinds of medium with disparate BMI exist dif erences. Using pairwise comparison,in TSC mediums,the counts of bacteria colony in overweight and lean group were both higher than normal group,but without statistical significance ( >0.05);In PS mediums,the counts of bacteria colony in lean group contained significant increase than normal group ( <0.05);In EMB mediums,the counts of bacteria colony in lean group were significant more than both normal and overweight group,besides,with the development of BMI index,a decreased trend showed in number of bacteria.Conclusion There are quantity variances of bacterial structure in undergraduates' excrement with dif erent BMI.
