呼吸道感染是常见的一种感染性疾病,是由于机体免疫低下、病原微生物入侵等多种因素综合作用造成呼吸道微生态平衡的结果,至今无特效的预防手段。Belliveau早在1973年就提出了呼吸道正常菌群与病原菌感染的关系。近年来,研究呼吸道微生态也成为了研究者关注的焦点[1-2]。如何在保护微生态的基础上,通过恢复和调整菌群平衡达到治疗疾病、消除感染成为呼吸病学领域的新课题。为了解青年上呼吸道正常微生物菌群情况,本研究
Respiratory tract infection is a common infectious disease, which is caused by the combination of many factors, such as low immunity and pathogenic microorganisms, resulting in the micro-ecological balance of the respiratory tract. So far, there are no effective preventive measures. As early as 1973, Belliveau proposed the relationship between normal respiratory flora and pathogen infection. In recent years, the study of respiratory microecology has also become the focus of researchers [1-2]. How to protect the micro-ecology on the basis of recovery and adjustment of flora balance to achieve the treatment of disease, eliminate infection has become a new topic in the field of respiratory disease. To understand the young upper respiratory tract normal microbial flora, this study
