Abstract: Objective The aim of this study was to investigate characteristics of ileal microbiota in patients with metabolic associated fatty liver disease (MAFLD). Methods 54 patients with MAFLD and 18 individuals for physical examination were recruited in our hospital between January 2024 and November 2024, all underwent FibroScan scan for controlled attenuation parameter (CAP) and endoscopy with special device for ileal specimen collection. 16S rDNA sequencing was performed. Results Patients with MAFLD in our series were divided into mild, moderate and severe liver steatosis, with 18 cases in each; patients with MAFLD had an elevated Alpha diversity of ileal flora, with a gradual decrease in percentage of Turicibacter, a reduction in abundance of Lactobacillus and Veillonella, while having an increase in the abundance of Prevotella, Leptotrichia and Porphyromonas. Conclusion The diversity and abundance of ileal microbiota in patients with MAFLD change, which is related to the severity of the entity. The reduction of Turicibacter and the migration of oral colonizing bacteria might be characteristics of the ileal microbiota in patients with MAFLD.
