Extended Data Fig. 6: Percentage of ARGs identified in the four hosts.

a, Percentage of ARGs identified in each of the four hosts uniquely (blue) and in overlap with at least one more host (red). E. coli identified only 57% of the 114 ARGs. b, On average, only 44% (labelled by a horizontal dashed line) of the detected ARGs overlap between pairs of species after accounting for the variability of the replicate screens (83%), that is dividing the percentage overlap between pairs of species by the percentage overlap between replicate screens (0.365/0.83). Data available in Source Data File 6. Boxplots show the median (center horizontal line), the first and third quartiles (bottom and top of box, respectively), with whiskers showing either the maximum (minimum) value or 1.5 times the interquartile range of the data; n = 80 for E. coli, n = 101 for K. pneumoniae, n = 56 for S. enterica and n = 37 for S. sonnei, where ‘n’ is the number of ARGs identified in the given host). Data is available in Supplementary Table 6.
