Figure 1

Complementary log-log plots of the empirical survivor functions S(t) versus time since challenge shown on a logarithmic scale. These are shown separately for each genotype group (only donor and recipient strains identified). The mortality phases are indicated by the steep early and late rises, although the timing and size vary between genotype groups. It is worth noting that three of the genotype groups (3, 6 and 9) do not fall in the envelope between the sensitive A/J and tolerant C57/BL strains, indicating additional trypanotolerance of these groups. A small separation between groups (<1 day) has been added to facilitate visual separation.
