Distribution of bacterial relative abundance among the three groups of faecal samples collected at farm #A: Cryptosporidium parvum-only-infected (n = 8), rotavirus-only-infected (n = 5) and pathogen-negative (n = 7). An average value for the relative abundance across the six sampling points for each genus is shown using a gradient scale. (a) The 261 analysed genera (Table S2) were plotted as rows in which the most abundant genus in the C. parvum-only infected group is shown at the top. The next most abundant genera are shown sequentially in order of abundance. (b) The 10 most abundant genera (shown on the left-hand side) in the C. parvum-only-infected group in comparison with the corresponding abundances in the rotavirus-only-infected and pathogen-negative groups. The top 10 genera were obtained from (a). A specific increase of Fusobacterium in the C. parvum-only-infected group was suggested. (c–e) Time-dependent change of bacterial relative abundance among C. parvum-only-infected, rotavirus-only-infected and pathogen-negative groups. The column titles are the numbers of faecal samples collected in each age in days (see Table S1).
