Background: Studies on microbiota characteristics of infants with small intestinal ostomy due to various etiologies are limited. Here, we investigated the intestinal microbiota of neonates with ileostomy due to different primary diseases.
Methods: Fifteen patients with necrotizing enterocolitis, eight patients with meconium peritonitis, and seven patients with Hirschsprung's disease were included in the study. The small intestinal microbiota composition in infants with ileostomy caused by different disease was investigated.
Results: The microbial diversity in neonatal ileostomy fluid was generally low, dominated by Proteobacteria and Firmicutes members. At the genus levels, the most abundant bacteria were Klebsiella, Escherichia-Shigella, Streptococcus, Clostridium sensu stricto 1, Enterococcus, and Lactobacillus. Streptococcus and Veillonella were related to carbohydrate metabolism and immunity, and breastfeeding could increase the proportion of these beneficial bacteria. The proportion of Bifidobacterium in the breastfeeding group was higher than that in the non-breastfeeding group, and the incidence of colitis and sepsis was significantly reduced in the breastfeeding group. The increase of body weight in the breastfeeding group was also higher than that in the non-breastfeeding group.
Conclusions: Excessive Klebsiella and Escherichia-Shigella and low abundance of Streptococcus, Veillonella, and Faecalibacterium indicated that the small intestinal microbiota was still in an unhealthy state. However, Streptococcus, Faecalibacterium, and Veillonella were commonly found, suggesting that these bacteria might promote the development of immune system after surgeries.
