采用人肠道菌群的培养与定量测定方法,利用4种选择性培养基,对本院大二学生及老年教师主要正常肠道菌群进行调查,结果显示:大二学生各类菌群均值(Log10n/克便)分别是:双歧杆菌:10.98±0.26;乳杆菌:8.27±0.57;肠杆菌:7.89±0.66;肠球菌:6.59±0.43。老年教师各类菌群均值(Log10n/克便)分别是:双歧杆菌:9.42±0.8;乳杆菌:8.02±0.59;肠杆菌:8.49±0.42;肠球菌:7.94±0.13。
Using the methods of culturing and quantifying human intestinal flora, using four selective culture media, the normal normal intestinal flora of sophomores and senior teachers in this hospital was investigated. The results showed that: (Log10n/g stool) were: Bifidobacterium: 10.98±0.26; Lactobacillus: 8.27±0.57; Enterobacteriaceae: 7.89±0.66; Enterococcus: 6.59±0.43. The average value of each group of geriatric teachers (Log10n/g stool) was: Bifidobacterium: 9.42±0.8; Lactobacillus: 8.02±0.59; Enterobacteriaceae: 8.49±0.42; Enterococci: 7.94±0.13.
