Pseudomonas aeruginosa (P. aeruginosa) is a Gram-negative, aerobic, rod-shaped and polar-flagella bacterium with unipolar motility. Furthermore, it is an opportunistic pathogen responsible for ventilator-acquired pneumonia (VAP). VAP due to P. aeruginosa is usually multidrug-resistant and associated with severe infection and increased mortality. The goals of this review are as follows: (I) to present selected recent epidemiological literature characterizing the population at risk of P. aeruginosa pneumonia, (II) to describe some of the virulence factors of P. aeruginosa that are related to infection, and (III) to illustrate clinical outcomes of ventilated patients with large burdens of P. aeruginosa as well as the mechanism by which this bacterium may evade the host immune response.

UI	MeSH Term	Description	Entries
D009894	Opportunistic Infections	An infection caused by an organism which becomes pathogenic under certain conditions, e.g., during immunosuppression.	Infection, Opportunistic,Infections, Opportunistic,Opportunistic Infection
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.	Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D011550	Pseudomonas aeruginosa	A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.

D014774	Virulence	The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenic capacity of an organism is determined by its VIRULENCE FACTORS.	Pathogenicity

D015331	Cohort Studies	Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
