Fig. 5.

Variation in mean anti-saliva IgG responses (a), mean anti-Leishmania IgG responses (b) and median clinical score through time (c). Dogs were classified as severe infections (filled circles, n = 23), recovered (crosses, n = 6) and mild infections (open circles, n = 18). Estimated time of patent infection is indicated by the vertical dotted line. Asterisks indicate a significant difference between groups after sequential Bonferroni correction by ANOVA (IgG) or Kruskal-Wallis test (clinical score) *P < 0.05, **P < 0.01, ***P < 0.001
