Transcriptional responses of Haemophilus parasuis to iron-restriction stress in vitro

Haemophilus parasuis is the causative agent of Glasser’s disease, which is responsible for the increasing economic losses in the pig industry worldwide. In this study, selective capture of transcribed sequences approach was used to investigate the transcriptional responses of H. parasuis to iron-restriction stress. Thirty-six genes were identified to be up-regulated under iron-restricted conditions. Knowledge of the genes involved in adaptation to environments encountered during disease will help understand the mechanisms of pathogenesis for this economically significant bacterium.
