Differences in microbial community between sick and healthy individuals. Principal Coordinate Analysis plots of microbial communities from all samples throughout the experiment, excluding the 8 samples taken from individuals when dead. Samples that were taken from an individual that was sick at the time of sampling are colored purple while samples that were taken from an individual that was healthy at the time of sampling are colored orange. Principal Coordinate Analysis was based on the weighted UniFrac distance matrix. Ellipses are drawn around each group’s centroid (confidence interval, 0.95).
