Principal Component Analysis (PCA) of OTU abundance for faeces (squares) compared to swabs (circles). a Overall comparison of all samples (n = 36) for each collection type. Canonical correspondence analysis (CCA) p = 1, b comparison of samples collected at the same time (n = 16)(CCA p = 0.98), c comparison of sample types collected at different times (n = 20) (CCA p = 0.99).
