医务人员肠道菌群生态分布初步调查

A Survey on the Criteria of Intestinal Flora of Medical Personnel

目的 调查医务人员肠道微生态菌群。方法 采集 30例大于 6 0岁老年健康医务人员及 32例小于 6 0岁中青年健康医务人员粪便 ,每例作需氧、厌氧和真菌培养、计数和鉴定。结果 共分离出 19种细菌 ;比较不同年龄组人群在 19种细菌中的差异 ,结果显示在肠杆菌、棒状杆菌、酵母样菌、非发酵革兰阴性杆菌、梭菌和厌氧球菌的数值上两组人群有显著差异 P<0 .0 5 ;比较不同性别组对 19种菌的数值差异表明 ,除乳杆菌外均无统计学差异 ,医务人员肠道菌群中的主要 6种菌 ,包括肠杆菌、肠球菌、拟杆菌、梭菌、双歧杆菌和乳杆菌均高于非医务人员 P<0 .0 1。

OBJECTIVE To survey on the oriteria of intestinal flora of medical personnel. METHODS To collect the feces of 30 cases of healthy senior medical personnel and 32 cases of healthy young people. The aerobic and anaerobic bacteria and yeast were cultured, counted and identified. RESULTS A total of 19 kinds of bacteria were isolated. To compare senior personnel with young ones, we found that there were significant differences (P<0.05) in enterobacillus, corynebacterium, yeast, non fermentative gram negative rods, clostridum and anaerobic counts (see Table 1). To compare male and female, there were no significant differences in 4 kinds, except lactobacillus (P<0.01). Among medical personnel the criteria of enterobacillus, enterococcus, bacteroides, clostridium, bifidobacteria and lactobacillus were significantly high than non medical ones (P<0.01). CONCLUSIONS The value of the fecal flora of medical personnel was significantly high than non medical ones.
