Objective to explore the influence of smoking on respiratory microbiota. Methods the traditional bacterial culture method was used to analyze the bacterial colonies qualitatively and quantitatively. The 16SrDNA fragment of characteristic bacterial colonies was amplified by PCR and sequenced, and then compared with the NCBI gene sequence library to analyze the changes of bacterial communities in the secretion of the pharyngeal wall of healthy smokers and non-smokers. Results the bacteria detection rate of smokers was significantly higher than that of non-smokers (P < 0. 05). Conclusion Smoking can increase the amount of bacteria in oropharynx and increase the incidence of pathogenic bacteria, so that the respiratory tract flora imbalance.
