Host-Pathogen Interaction in the Lung of Patients Infected withPseudomonas aeruginosa

Pseudomonas aeruginosa is an opportunistic bacterium that can proliferate in the soil, water, and even humans if they are immunologically depressed. During lung infections, P. aeruginosa goes through significant morphological changes turning into the mucoid form after which its eradication becomes almost impossible. Within this chapter, we explore the bioenergetics changes produced within P. aeruginosa during infections in humans and the metabolic pathways that are involved in those changes that lead to chronic infection.
