The oral microbiota has been observed to be influenced by cigarette smoking and linked to several human diseases. However, research on the effect of cigarette smoking on the oral microbiota has not been systematically conducted in the Chinese population. We profiled the oral microbiota of 316 healthy subjects in the Chinese population by 16S rRNA gene sequencing. The alpha diversity of oral microbiota was different between never smokers and smokers ( P = 0.002). Several bacterial taxa were first reported to be associated with cigarette smoking by LEfSe analysis, including Moryella ( q = 1.56E-04), Bulleidia ( q = 1.65E-06), and Moraxella ( q = 3.52E-02) at the genus level and Rothia dentocariosa ( q = 1.55E-02), Prevotella melaninogenica ( q = 8.48E-08), Prevotella pallens ( q = 4.13E-03), Bulleidia moorei ( q = 1.79E-06), Rothia aeria ( q = 3.83E-06), Actinobacillus parahaemolyticus ( q = 2.28E-04), and Haemophilus parainfluenzae ( q = 4.82E-02) at the species level. Two nitrite-producing bacteria that can increase the acidity of the oral cavity, Actinomyces and Veillonella , were also enriched in smokers with FDR-adjusted q -values of 3.62E-06 and 1.10E-06, respectively. Notably, we observed that two acid production-related pathways, amino acid-related enzymes ( q = 6.19E-05) and amino sugar and nucleotide sugar metabolism ( q = 2.63E-06), were increased in smokers by PICRUSt analysis. Finally, the co-occurrence analysis demonstrated that smoker-enriched bacteria were signi...
