Antibiotic resistance, virulence factors and genotyping of Pseudomonas aeruginosa in public hospitals of northeastern Mexico.

Introduction: Pseudomonas aeruginosa is the second most prevalent opportunistic pathogen causing nosocomial infections in Mexico. This study evaluated antibiotic resistance, production of virulence factors and clonal diversity of P. aeruginosa strains isolated from patients undergoing nosocomial infections in public hospitals of northeastern Mexico.
