Figure 4:

Principal components analysis (PCA) illustrating relationships among Batrachochytrium dendrobatidis (Bd) load, bacterial killing ability (BKA), growth rates and neutrophil/lymphocyte (N/L) ratios in uninfected frogs (n = 11, purple), Bd-infected individuals that did not develop chytridiomycosis (n = 10, green), Bd-infected individuals with chytridiomycosis (n = 6, blue) or Bd-exposed individuals euthanized during early infection, before disease signs occurred (n = 5, pink). Corresponding ellipses represent 68% confidence intervals for each group. Individuals with missing data for any of the above parameters were excluded from the PCA by necessity, resulting in smaller sample sizes.
