Summarized WSS scores for infants without antibiotic treatment. All pre-processed DNA sequences from Yassour et al. (19) infants without antibiotics were used to compare each infant's last day of the experiment sample (3-year) to every possible pair of the same infant's samples (<6 months, 1-, and 2-year). Twenty species with known WSS cutoff values were identified. The WSS scores for each infant pair that was above the cut-off at some time (<6 months, 1-, and 2-year) compared with the 3 year sample (related) was a green box while samples (<6 months, 1-, and 2-year) compared to 3 years that were all below the cut-off (unrelated) was a purple box. Each column in the table represents an individual's ID and matches the number shown in the Supplementary Table 1. WSS scores for all identified species are provided in the Supplementary Table 4. For delivery mode, V stands for vaginal birth and C for cesarean section birth.
