Pseudomonas aeruginosa is a pathogenic microbe that has a wide variety of opportunistic infections, including surgical site, urinary tract, pneumonia and bloodstream, wounds and burns, ear, nose, and throat infections, as nosocomial infections in the hospital intensive care units (ICUs). Nineteen isolates of P. aeruginosa from burns and wounds were collected. All isolates also were subjected to the cultural, biochemical tests as well as vitek 2 system. Moreover, these isolates had been tested for susceptibility to (10) antibiotic discs and also detection of some virulence factors included hemolysin, pyocyanin, swarming motility, and biofilm formation. Most isolates were resistant to tetracycline, imipenem, and doxycycline, whereas they showed more sensitive to amikacin, tobramycin, and aztreonam. P. aeruginosa had been showed different range for hemolysin activity, pyocyanin and swarming motility, furthermore they varied (moderate and weak) for biofilm formation.
