FIGURE A2.

Source attribution proportions of four selected multi‐locus sequence types (STs) to three sampled sources in 10 models (M1–M10, left to right). Four models (M1, M3, M5, and M8) also include a fourth, “unsampled source.” See Table 1 for more details about the models. ST50 (C. jejuni) was the most observed type in cases, ruminants, and pigs and the fifth most common type in chickens. ST48 (C. jejuni) was fourth most common type in humans, but rare or absent in all sources. ST827 (C. coli) was the second most common type in chickens, and found in the other sources, but relatively uncommon in cases. ST2398 (C. jejuni) was more common in cases than ST827, but not detected in any sources. Estimates of relative abundance of these types in the respective sources can be found in Tables A3 and A4. Estimates of the transmission potential of the four types can be found in Table A6.
