The Pseudomonas aeruginosa alternative sigma factor PvdS controls exotoxin A expression and is expressed in lung infections associated with cystic fibrosis

1 Oct 2002

Abstract excerpt

PvdS is an alternative sigma factor regulated by the global iron regulator Fur. It has been demonstrated that PvdS plays a role in the iron-dependent regulation of exotoxin A (ETA) in Pseudomonas aeruginosa strain PAO1. The goals of this research were to determine if pvdS was transcribed by the bacteria in the chronic lung infections associated with cystic fibrosis (CF) and to determine how PvdS interacts with...
