Abstract: 【Objective】 To analyze the changes of gut microbes in patients with postpartum depression so as to explore the relationship between postpartum depression and gut microbes. 【Methods】 A total of 60 postpartum subjects were recruited to participate in this study. The depression status of the participants was scored using the Edinburgh Postpartum Depression Scale (EPDS). Those with a score ≥13 were included in the postpartum depression group (PPD group), while those with a score less than 13 were included in the postpartum healthy control group (PPHC group). The feces of these 60 subjects were collected, and the fecal whole genome DNA was extracted for 16S rDNA sequencing. The data of changes in the bacterial diversity between the groups were obtained, and the possible correlation between the changes of intestinal microbes and postpartum depression was analyzed. 【Results】 The number of microorganisms in PPD patients was significantly reduced (P<0.001); the Chao1 index (P<0.001) and ACE index (P<0.001) of α diversity decreased significantly. There were also significant differences in β diversity between the two groups. Analysis of the bacteria in the groups showed that Acetanaerobacterium, Adlercreutzia, Allobaculum, Alloprevotella, Bifidobacterium, Christensenella, Escherichia, Eubacterium, Faecalicatena, Fusobacterium, Haemophilus, Intestinimonas, Lactobacillus, Megamonas, Monoglobumus, Muribaculum, Oscillospira, Paraprevotella, Streptococcus, Raoultibacter, Ruminococcus and Stomatobaculum were significantly enriched in PPHC group. In contrast, Kineothrix, Lachnoclostridium, Acinetobacter, Aquisphaera, Enterococcus, and Mucispirillum were enriched in PPD group. RDA/CCA analysis showed that EPDS was positively correlated with Prevotella, Kineothrix, and Alistipes, but negatively correlated with Lachnospira. 【Conclusion】 This study found that the intestinal flora of patients with postpartum depression was significantly disrupted, and there was a correlation between the intestinal flora and postpartum depression symptom score. Therefore, intestinal microbial markers may contribute to the diagnosis and treatment of patients with postpartum depression.
