Infections in the immunocompromised host. Patients who are immunosuppressed, particularly transplant recipients, burn patients, and patients with cancer and with neutropenia, are at increased risk of acquiring P. aeruginosa infection (22–24).
Abstract
Infections with Pseudomonas aeruginosa have become a real concern in hospital-acquired infections, especially in critically ill and immunocompromised patients. The major problem leading to high mortality lies in the appearance of drug-resistant strains. Therefore, a vast number of approaches to develop novel anti-infectives is currently pursued.
Introduction
One of the most important challenges for physicians is the adequate treatment of infections due to Gram-negative pathogens because of the increasing antimicrobial resistance in the healthcare setting [ 1 ].
Risk factors for antimicrobial resistance in P. aeruginosa
Multi-drug resistance (MDR) has increased dramatically in recent years and is now recognized as a major threat worldwide [ 7 ]. Risk factors for the development of MDR strains have been evaluated in several studies.
Mechanisms of antibiotic resistance
Bacteria exhibit multiple resistance mechanisms to antibiotics including decreased permeability, expression of efflux systems, production of antibiotic inactivating enzymes and target modifications. P.
Laboratory role
Diagnostic laboratories need to implement several methodologies and procedures to identify P. aeruginosa strains and rapidly provide antibiotic susceptibility testing (AST) for the management of antibiotic regimens.

P. aeruginosa bloodstream infection (BSI) is a serious disease that requires prompt attention and pertinent clinical decisions in order to achieve a satisfactory outcome. Currently, Pseudomonas spp.
Management of P. aeruginosa VAP
P. aeruginosa is one of the leading causes of ventilator-associated pneumonia (VAP) in the US and Europe [ 77 – 79 ]. VAP due to P. aeruginosa is increasing in incidence and poses unique challenges for its clinical management. Risk factors for the development of P.
Why is Pseudomonas aeruginosa important?
Pseudomonas aeruginosa is an important cause of nosocomial pneumonia associated with a high morbidity and mortality rate. This bacterium expresses a variety of factors that confer resistance to a broad array of antimicrobial agents.
Why is empirical antibiotic therapy inadequate?
Empirical antibiotic therapy is often inadequate because cultures from initial specimens grow strains that are resistant to initial antibiotics. Surveillance data, hospital antibiogram and individualization of regimens based on prior antibiotic use may reduce the risk of inadequate therapy.

Antibiotic combination s that yield some degree of susceptibility in vitro are the recours e, although the efficacy of these regimens has yet to be established in clinical studies. Experimental polypeptides may provide a new therapeutic approach.

aeruginosa infections in people with non-CF bronchiectasis. According to these guidelines, oral ciprofloxacin is a preferred treatment for a first infection, and intravenous treatment is to be considered for people who do respond. Resistant strains of this bacteria likely require combination antibiotic treatment, including ciprofloxacin, and combinations are recommended for bronchiectasis patients who “will require many subsequent antibiotic courses to reduce the development of drug resistance.”

Nebulized colistin is also a potential treatment for this infection.
Why do bacteria persist in the airways?
