The proportion of individuals surviving following a challenge ((a) challenge with Bt1, (b) challenge with Bt2, (c) challenge with Bs, (d) challenge with Ec) when they had been previously primed with either a homologous (filled circles: (a) Bt1–Bt1, (b) Bt2–Bt2, (c) Bs–Bs, (d) Ec–Ec) or different levels of heterologous bacteria (open circles: (a) Bs–Bt1, (b) Ec–Bt2, (c) Bt1–Bs, (d) Bt1–Ec; filled down triangles: (a) Bt2–Bt1, (b) Bs–Bt2, (c) Bt2–Bs, (d) Bt2–Ec; open up triangles: (a) Ec–Bt1, (b) Bt1–Bt2, (c) Ec–Bs, (d) Bs–Ec). Filled squares represent animals that were left naive at the priming; open squares represent animals that were treated with Ringer's solution at the priming.
