title: Different paths to pathogenesis.
abstract: In a recent issue of Cell Host & Microbe, Elsen and colleagues identify a novel hemolysin in a highly virulent Pseudomonas aeruginosa strain that lacks a type III secretion system. Their analysis provides another example of how individual strains of P. aeruginosa utilize different virulence mechanisms to cause severe infections.
