摘要
本文以厌氧菌双歧杆菌、需氧菌肠杆菌为代表对46例足月新生儿、15例早产儿出生后肠道细菌的定植进行了详细观察,并对早产儿进行动态观察。结果发现,首先肠道定植细菌是肠杆菌,后为双歧杆菌。分娩方式、喂养方式、早产、温箱护理和应用抗生素可影响肠菌群的定植,而且剖宫产儿、早产儿肠道双歧杆菌开始定植及达优势化时间均较晚.其研究结果为指导临床治疗、护理和婴幼儿保健提供了理论依据。
The fecal flora of E. Coli and bifidobacteria were investigated ia 46 full-term and 15 premature cases which collected from neonates, sequencial and dynamic observation of premature was done. Results showed that the first colonized intestinal flora was E. Coli then laterly was bifidobacteria; and that such relevant factors as different modes of delivery, different types of feeding and premature labor did have significant influence on early intestial flora colonization; compared with full-term neonates,the time when bifidobacteria became colonized and predominated at the intestine was retarded in such infants as those of abdominal section premature labor and bottle-fed. Similarety for infants nursed in an incubator or often treated with antibiotics,the intestinal flora colonization of bifidobacteria was also delayed. Thus, present study may provide some valuable clues for infant treatment nursing and health care.
