The presence of exotoxin genes and biofilm production in carbapenem-resistant Pseudomonas aeruginosa clinical isolates

<i>Pseudomonas aeruginosa</i> clinical isolates were resistant to many anti-pseudomonal antibiotics. Most of isolates were biofilm-producers. The genes <i>exoT</i>, <i>exoS</i> and <i>exoY</i> were identified in almost all <i>P. aeruginosa</i> strains and are considered an inevitable component of <i>P. aeruginosa</i> virulence.
