Figure 2.

Kaplan-Meier graphs for Galleria mellonella (full lines) and Caenorhabditis elegans (dashed lines) survival after infection with Burkholderia cenocepacia clonal isolates retrieved from patient AB during 12.5 y of chronic infection. Results for G. mellonella and C. elegans were obtained as described in materials and methods and as used for patient J isolates in Figure 1. Statistical analysis was performed to compare the virulence potential between the first isolate retrieved from the patient, IST4121, and each of the other isolates for C. elegans (left side of the slash) and G. mellonella (right side of the slash) (* p < 0.05, ns not significant, Mantel-Cox test).
