广东地区健康人肠道菌群调查分析

A SURVEY ON INTESTINAL FLORA OF EALTH PEOPLE IN GUANG DONG PROVINCE

用直接快速涂片和缩小视野时钟法,检查粪便细菌分布,并与大便菌群培养定量计数比较,观察分析82例不同年龄组广东健康人群。结果表明:老年组(60 岁～78 岁)和儿童组(3 岁～10 岁)较婴儿组(3 月～12 月)的G- b有明显增加(P< 0.05)。男女性别无显著差异:G+ b 和G- b 的数量,随着年龄的增加而减少;G+ c 则随着年龄增加而增加。通过本次调查我们认为缩小视野时钟法,快速准确简便,容易掌握,价格低廉。

By direct smear method、contracted Sight-scale clock method and breeding of fecal flora, the fecal flora from 82 cases of different age gruops were observed. The results show that in the old-age groups(60-78 years old )and children group (3-10 years old), the amounts of G +b and G -b comared with infant group (3-12monthes), decreased definitely(P<0.05); The amount of G +c in infant group (3-12montues) are obviously lower than that of other groups(P<0.05), There is not any difference between the males and the females in all of the groups (P>0.05). The results suggest that the amounts of G +b and G -b in the intestines decreased with aging, whereas G +c and G -c increased. By this experiment we think contracted sight-scale clock method is a exact; simply cheap and rapid method and esay for cliuicians to master
