Linear discriminant analysis (LDA) effect size (LEfSe) at species level of Illumina sequencing datasets based on 16S rRNA gene sequences. Nine differentially abundant bacterial species were detected (p = 0.05, LDA score > 3.0) at species level. Of these, 8 bacterial groups were significantly over-represented in brachycephalic dogs (blue) and one bacterial group was over-represented in dogs of terrier breeds (yellow)
