1Diversity change indicates whether the number of unique strains increased, decreased, or stayed the same after SDC consumption. Patient number 1 is identified as A1, patient number 5 as A5, etc.
-
2Five E. coli strains were isolated from rectal swabs pre- and post-consumption, and the number of unique fingerprints was determined using Diversilab™ DNA-fingerprinting. Strains were compared using KL clustering, and strains that were ≥95% similar were considered identical and those <95% similar were considered unique. A type designated as 5/0 means that all 5 strains were ≥95% similar and there were no unique strains.
-
3When the DNA fingerprints of all five rectal E. coli isolates were the same, the diversity measure was zero. As the number of unique fingerprints increased, the diversity measure becomes an increasingly negative number.
