Infection parameters present common determinants evidenced by linear discriminant analysis. Infecting parasite strains (A), phase (B) intestinal (D) and cardiac (G) damage can be efficiently grouped using one-dimensional (B) or two-dimensional (A,D,G) plotting. Each element stands for an animal; points stand for centroids of the group in 2-dimensional graphs; dotted lines stand for the mean of the groups in panel B. Functions used for plotting were calculated by discriminant analysis; their matrices of structure are presented in Table S7. Panels C (for panel B), E and F (for panel D), H and I (for panel G) present the correlation of the parameters to the discriminant function (x axis) and the corresponding inter-class variance of the indicated groups, presented as its cubic root for visualization purposes. Triangles indicate variables whose mean was significantly different between the two indicated groups; points stand for no differences in their means.
