Review Meta AnalysisA systematic review and meta-analysis on Exo-toxins prevalence in hospital acquired Pseudomonas aeruginosa isolates.
Pseudomonas aeruginosa (PA) is an opportunistic pathogen that produces widespread and often overwhelming infections. Among different virulence factors, toxins are important bacterial agent which increases PA pathogenesis especially in immunocompromised patients. The aim of this meta-analysis was to determine the prevalence of exotoxin production in PA isolates in the world. Also according to the importance of drug resistance in isolates with more pathogenicity this estimation was conducted in resistant isolates. ⋯ This first meta-analysis on PA isolates with toxin potency indicated high prevalence of exotoxin production in clinical isolates of PA which is an alarming point as a clinical aspect. It was found that the ExoT has the most prevalence rate among toxins. The results of simultaneous evaluation of exotoxins and antimicrobial resistance can develop treatment policies against PA infections in hospitals and hospitalized patients.
