All flies were ultimately killed by the infecting pathogen. Wild type, resistant, or sensitive refer to changes in survival relative to wild-type flies. Flies were injected with 50 nl S. typhimurium (OD₆₀₀ = 0.1) or L. monocytogenes (OD₆₀₀ = 0.01) and incubated at 29°. Significance was determined by log-rank test. n = 30 flies. See Figure 1 for survival curves of lines that were significantly sensitive or resistant to bacterial challenge.
