Figure 1From: Insect immunity: oral exposure to a bacterial pathogen elicits free radical response and protects from a recurring infectionLarval survival after septic injury. The four survival curves present different priming-injection groups, where the first term is bacteria used in the priming, and second term bacteria used in septic infection 120 h later. Ec stands for the control bacterium, E. coli, and Sm for S. marcescens. Treatments from the least to the most virulent combination: Ec-Ec < Sm-Ec < Sm-Sm < Ec-Sm.Back to article page
