Table 1. Results of the GAM for parametric effects (temperature (T) and genotypes a-g (G) and smoothed interaction (genotype by temperature (f(GxT))) on net production of uninfected and infected host cells mL^–1 in parasite exposed cultures, on net change in infection prevalence and on the net reduction of production of uninfected host cells mL^–1.
