Abstract
The objective was to analyze the virulence factors dependent on Cuorum Sensing and drug resistance in strains of Pseudomonas aeruginosa. Virulence factors such as pyocyanin, beta-lactamase, biofilm, and antibiotic resistance were determined in 95 strains of P. aeruginosa isolated from hospitalized patients. Genus and species were identified by protein analysis by MALDI-TOF. 100% of the strains were resistant to at least one drug and the highest proportion was 32 strains resistant to 4 drugs and 5 resistant PAM strains. In the analysis of virulence factors, 98.8% produce at least one virulence factor and 48.9% are beta-lactamase producers. Therefore, it is concluded that P. aeruginosa strains isolated from clinical samples constitute a risk factor for hospitalized patients.
