新生儿肠道细菌定植研究进展

细菌定植是发生医院内细菌感染的先兆,一种细菌的定植率代表了发生该菌感染的风险性.新生儿是医院感染的高危人群,近年来研究表明阴道分娩、母乳喂养、益生菌的应用等措施可降低肠道致病菌的定植,从而减少新生儿肠源性感染的发生.然而影响肠道菌群定植的因素很多,且受试验条件的限制,很多问题尚待进一步研究.

Progress in neonatal bacteria colonization

Bacterial colonization is a sign of bacterial infection in the hospital, and the bacterial colonization rate indicates the risk of bacteria infection. Newborn infection happen easily in the hospital. In recent years, sereral researches indicate that vaginal delivery, breastfeeding and probiotics usage and so on can lower the probability of intestinal pathogenic bacteria colonization, which can lower the probability of neonatal enterogenous infection. Therefore, there are many factors that can effect on newborn intestinal bacteria colonization, and because experimental conditions are limitated, so we have many problems to solove in the future.
