From: Perturbation and restoration of the fathead minnow gut microbiome after low-level triclosan exposure
Triclosan exposure shifts gut microbial community structure. (a) Samples cluster by exposure level immediately following acute triclosan exposure (day 7). After 1 week (b) and two weeks (c) of unexposed recovery (day 14 and day 21), samples are no longer separated by triclosan exposure history. Multi-response permutation procedure (MRPP) significance testing using the weighted UniFrac distance matrices shows that clustering of exposed and unexposed samples is highly non-random at day 7 (A = 0.194, P = 0.0003), but is no longer defined by exposure on day 14 (A = 0.056 P = 0.043) and day 21 (A = 0.003, P = 0.385).
