Supplementary Table 1. Bacterial alpha diversity assessed using the Chao1 richness estimate, OTU
richness, and Shannon Index, with Kruskall-Wallis test of K samples with a controlled multiple pairwise comparison. Significant differences in measures are indicated using standard notation; samples
that share a letter are not significantly different, while samples that do not share a letter are
significantly different. In this table, we see room 4 is significantly different than rooms 1, 2 and 3 for all
measures (p<0.001).

Supplementary Table 3. Controlled ANOVA tests identified genera whose relative abundance
differed significantly between room groups (cont p < 0.05). Based upon controlled ANOVA using least
square means this table lists significantly different genera between groups (p < 0.05). The LS mean
for each genera and group is provided. Group indicates which room group. Each genus with
significant differences is indicated along with their LS mean and their relative significance. Groups
which share a letter are not significantly different from each other while groups which do not share a
letter (A, B, C) are significantly different (thus, a group which has A is significantly different from a
group which only has letter B, while a group with letter A is not significantly different from a group
which has AB).
