Abstract
Background: Pseudomonas aeruginosa has developed different mechanisms of resistance against antibiotics and became one of the most life-threatening pathogens. Fighting against its virulence Factors are an alternative therapeutic target. Objective: This study was directed towards the investigation of anti-quorum sensing activity and inhibitory action on virulence factors of different agents including antibacterial agents to which Pseudomonas aeruginosa isolates are resistant and non-antibacterial agents. Methodology: Anti-quorum sensing activity of ceftriaxone, ceftazidime (CAZ), cefepime (FEP), vancomycin (VA), paracetamol (PA), and pheniramine maleate (PHE) investigated as well as their ability to reduce other virulence factors including protease, hemolysin, and pyocyanin production. Results: This study showed that 3rd and 4thgenerations cephalosporins could be used as anti-quorum sensing agents effectively in the treatment of Pseudomonas aeruginosa infections, however, vancomycin, paracetamol, and pheniramine maleate had no effect on inhibiting the studied virulence factors. Conclusion: From our study we conclude that although cephalosporins at the used concentrations did not show anti-pseudomonal activity they were effective as anti-virulent agents that could be utilized in therapeutically in controlling Pseudomonas aeruginosa infections.
