A comparison of the major microbial changes seen in the gut microbiotas for IBD and NEC

IBD	NEC
Increased abundance of Proteobacteria	Increased abundance of Proteobacteria
Decreased abundance of Firmicutes	Decreased abundance of Firmicutes
Increased abundance of Enterobacteriaceae	Decreased abundance of Bacteroidetes
Decreased abundance of Faecalibacterium prausnitzii	Increased abundance of Klebsiella

A comparison of the major microbial changes seen in the gut microbiotas for IBD and NEC. The differences in abundance of some organisms is outlined for IBD and NEC for comparison. Abundances are relative abundances and may be changes associated with each disease before, during or after disease onset.

IBD, inflammatory bowel disease; NEC, necrotising enterocolitis.
