Treatment response for the different bacterial and worm strain combinations of the main experiment. The response is expressed as host condition (values for the whole experiment), such that the black area refers to the proportion of dead worms, grey to the proportion of morbid, and white to the proportion of live worms. For C. elegans, both strain (bottom line) and genotype (top line) designations are given. For S. marcescens, only strain names are listed.
