Pseudomonas aeruginosa virulence factors as a therapeutic target in multidrug-resistant strains
Pseudomonas aeruginosa (PSAE) is known for its ability to form biofilm and produce other virulence factors associated with a resistant phenotype. Multidrug-resistant (MDR) PSAE strains represent a serious problem in healthcare and are the focus of an increasing number of studies dealing with the therapy of infections caused by these bacteria. Nowadays, a number of studies focus on the presence of virulence factors rather than on the mechanisms of resistance to the antibiotics used, as it is the study of virulence factors that makes it possible to expand the possibilities of effective and efficient therapy. This review describes the virulence factors produced by the one of the five PSAE secretion systems that have the potential to become targets for so-called antivirulence therapy, have been described. These are mainly alkaline protease, elastase B, exotoxins A, S and Y and pyocyanin. In addition to specific virulence factors, recent studies have focused on the components of the PSAE secretion systems that mediate the transport of toxins and lytic enzymes out of the bacterial cell. Inhibition of specific molecules for type 2 and 3 secretion systems may prevent secretion of virulence factors into the extracellular space and host cells, which would have a significant impact on reducing PSAE virulence.
