[Antimicrobial susceptibility and molecular mechanisms of resistance to beta-lactams of gram-negative microorganisms--causative agents of nosocomial infections].

Profiles and mechanisms of resistance to beta-lactam antibiotics of isolates of Gram-negative microorganisms, which are causative agents of infections in Intensive Care Unit of hospital surgery department, were studied. Two hundred and ten clinical isolates were studied: Pseudomonas aeruginosa--86 strains (40.9%), Acinetobacter baummanii--45 strains (21.

[Resistance epidemiology of gramnegative nonfermenting pathogens of nosocomial infections in intensive care units and surgical departments].

Etiological structure, patterns and antibiotic resistance mechanisms of gramnegative nonfermenting pathogens of nosocomial infections isolated from patients in intensive care units and surgical departments were investigated. One hundred thirty one clinical isolates, including 86 (65.6%) isolates of Pseudomonas aeruginosa and 45 (34.
