ABSTRACT
Objective To investigate the differences of gut microbiota between patients with abdominal aortic aneurysm and atherosclerosis.Methods From December 2018 to June 2019,20 fresh stool samples were collected respectively from the patients with abdominal aortic aneurysm and atherosclerosis treated at the Department of Vascular Surgery,Peking Union Medical College Hospital.The 16S rDNA high-throughput sequencing was employed to compare the composition,abundance,and α and ß diversities of gut microbiota between the two disease groups,and further determine the significantly differential genera.Results The two groups had great similarities in the composition of gut microbiota.There was no statistical difference in α diversity.Although ß diversity did not have statistically significant difference,certain microbial taxa showed differences between the two groups.The LEfSe demonstrated that the abdominal aortic aneurysm group had higher relative abundance of Leuconostocaceae,Ruminococcaceae,Weissella,and Faecalibacterium while lower relative abundance of Firmicuteria,Selenomonadales,and Veillonellaceae.Conclusion The structure of gut microbiota has differences between patients with abdominal aortic aneurysm and atherosclerosis,and sample size should be enlarged to validate the results.
