不同喂养方式对婴儿肠道微生态的影响

目的 探讨不同喂养方式对婴儿肠道微生态的影响。 方法 在湖南省某市募集200名0~6月龄婴儿为研究对象,问卷调查,收集婴儿基本资料,采用经典的传统微生态培养方法,检测不同喂养方式婴儿肠道微生态主要组成成分。 结果 母乳喂养组婴儿粪便中乳酸杆菌[(4.906 2±0.689 6) vs. (4.383 4±0.439 2)CFU/g]、双歧杆菌[(7.644 9±0.535 3) vs. (7.438 2±0.359 4)CFU/g]和拟杆菌[(7.820 7±0.590 0)vs. (7.607 9±0.379 7)CFU/g]显著高于人工喂养组婴儿(P＜0.05);其它指标(肠球菌、肠杆菌、产气荚膜梭菌、葡萄球菌、其它肠杆菌、其它厌氧菌和其它需氧菌)两组比较差异无统计学意义(P＞0.05)。 结论 母乳喂养婴儿肠道微生态优于人工喂养组婴儿。

Effects of different feeding modes on intestinal microecology of infants

Objective To explore the effects of different feeding Methods on the intestinal microbial ecology of infants. Methods We recruited 200 infants aged 0-6 months in a city in Hunan Province to serve as the research subjects. A questionnaire survey was conducted to collect the infants' general information. The major components of intestinal microbial ecology of infants with different feeding ways were detected by classical microecological culture method. Results The number of lactic acid bacteria (4.9062±0.6896 vs. 4.3834±0.4392 CFU/g), Bifidobacterium (7.6449±0.5353 vs. 7.4382±0.3594 CFU/g) and Bacteroidaceae (7.8207±0.5900 vs. 7.6079±0.3797 CFU/g) was significantly higher in the breast feeding group than in the artificial feeding group (P<0.05). And no statistically significant differences were observed in other indicators (including Enterobacter, Enterococcus, Clostridium perfringens, Staphylococcus aureus, other enterobacteriaceae, other anaerobic bacteria and other bacteria) between the two groups (P>0.05). Conclusions The intestinal microecology of infants with breast feeding is superior to that of infants with artificial feeding.
