Abstract

Continual monitoring of hospital ECO system and its antimicrobial susceptibility is an imperative in prevention of endemic hospital infection. The aim of this paper was to present the significant changes in dynamic balance and antibiotic resistance in the hospital ECO system of the surgical Intensive Care Unit in the period of 15 years (1991-2007). The results obtained have shown decreased isolation of gram negative bacilli from 90% (1991) to 63% (2007)and significant increased isolation of Staphylococcus aureus. Structure of microorganisms found in hospital setting during 1991-1994 was: Pseudomonas aeruginosa (41%), Acinetobacter spp. 2006-07:Staphylococcus aureus (32%), Acinetobacter spp.(27%), Pseudomonas aeruginosa (14%), and Klebsiella aerogenes (11%) Proteus mirabilis (9%), E. coli (5%). The analysis revealed that Pseudomonas aeruginosa was pushed out from the first to the third place, being replaced by Staphylococcus aureus, mainly MRSA(87% out of the total SA). There were endemic strains of enterobacteria (multiresistant Proteus mirabilis, E.coli and Klebsiellaaerogenes), which had no significant importance in causing infection in ICU 15 years ago. Acinetobacter spp. has proved to be a very important hospital pathogen over the last 3 years within its population there has been an increase of strains of extremely multiresistant mutants that are susceptible only to imipenem (10% of resistance) and greatly enlarged resistance percentage to amikacyn (80%). Conclusion 1. The MRSA has become a common nosocomial pathogen in investigated ICU instead of Pseudomonas aeruginosa. 2. Continual monitoring of ICU should be implemented in order to perceive changes in the ICU dynamic balance on time.
