16S rRNA sequencing of tongue coating microbiota in patients with pulmonary nodules
This study aimed to characterize the tongue coating microbiota of patients with pulmonary nodules and to compare microbial community differences between patients with greasy tongue coating and those with non-greasy tongue coating. Tongue coating samples were collected from patients with pulmonary nodules, and 16S rRNA gene sequencing was performed to investigate the composition and diversity of the tongue coating microbial communities. The results may provide insights into the microbial characteristics associated with different tongue coating phenotypes and contribute to a better understanding of the relationship between oral microbiota and pulmonary nodule status.
