  1. Results for model: untransformed tumour necrosis factor alpha (TNF-α) (pg/ml) ~sex + snout-vent length + season + trap group; random model, trap day/process day/assay plate.
  2. †The TLR2/zymosan general linear mixed model for untransformed TNF-α was a relatively poor fit to the data, but results for this model, which are highly consistent with model predictions for the other variables, are presented to maintain direct comparability. TIR = total TNF-α (pg/ml) response summed over all receptor-ligand combinations. Standard errors are given in parentheses.
  3. ‡Percentage change between the uninfected and heaviest infection categories.
