Firmicutes and Proteobacteria are most abundant phyla in the faecal microbiota of all study subjects. Relative abundances of bacterial phyla and families detected in faecal samples from Strongyloides stercoralis infected and uninfected subjects (S+ and S−, respectively) and of the subset of S+ subjects that had received anthelmintic treatment (associated sub-circles), both prior to (S+pre-treatment) and 6 months post-ivermectin administration (S+post-treatment). Percentages in individual pie chart sections indicate the relative proportion of a given bacterial phylum or family.
