FIG. 8.

Lethality of strains from CF patients simultaneously infected with multiple Pseudomonas strains. (A and B) The lethality of Pseudomonas CF isolates from patient 57 (A) and patient 89 (B) was graphed. The pathogenic potential of strains was determined by fly nicking. The strains shown in panel A are 14660 (▴) and 14661 (▪), and the strains shown in panel B are 14649 (○), 14651 (⧫), and 14650 (•). The data are representative of the assay performed twice in triplicate, with error bars representing the standard error of the mean.
