A Average dissimilarity (Morisita-Horn distance) of skin recipient communities at baseline (T00) and collection times following the transfer event to respective soil, leaf, and skin donor bacterial communities. Zero value indicates perfectly similar communities; value of 1 indicates perfectly dissimilar communities. B Subjects who participated in the soap and water wash 8 h after the transfer event had a more dramatic increase in dissimilarity than those assigned to the 24-h post-transfer collection group, suggesting that washing is more effective than time at reducing the imprint of environmental bacterial sources
