(a) Proportion of successful infections as a function of bacteria virulence (indicated here by their lethal time 50 (LT₅₀), highly virulent lineages having low LT₅₀). (b) Reproductive success as a function of bacteria LT₅₀. (c) Reproductive success as a function of XaxAB-dependent haemolytic activity. Haemolytic activity is measured as the proportion, for each lineage, of clones that display the full haemolysis phenotype. (d) Proportion of surviving IJs after 56 days spent at 28°C, as a function of the average number of bacteria they carry. In all figures, point size indicates haemolytic activity (filled circles, ancestral lineages; triangles, LDI; open circles, HDI).
