Microbiota composition of shed leech mucus obtained through Illumina sequencing of the V3-V4 hypervariable region of 16S rRNA gene. (A) The relative abundance of total reads, following quality control, within phyla. (B) The relative abundance of reads, comprising ≥2% of total reads, of genera housed within Proteobacteria. ^*Indicates previously described within the leech (Worthen et al., 2006; Kikuchi et al., 2009). (C) The relative abundance of reads, comprising ≥1% of total reads, of genera housed within Bacteroidetes.
