[Considerations regarding the nosocomial potential of surgical wards]

Abstract

Purposes: The aim of our study was to determine the prevalence of multiresistant germs with nosocomial potential and their main resistance phenotype and genotype patterns in surgical departments.

Methods: Identification of germs was performed by the API system (BioMerieux France) and susceptibility tests by disk-diffusion tests, (CLSI standards) with automatic reading methods (Osiris-Bio Rad Laboratories). ESBL producing E. coli and Klebsiella pneumoniae strains have been also genotyped.

Results: From 190 samples (urines, wound secretions, blood, etc.); we isolated 106 microbial strains with nosocomial potential. 56 (52.83%) from these strains were represented by enterobacteria, 26 (24.52%) by Gram negative non-fermentative rods, and 24 (22.64%) by Gram positive cocci.

Conclusions: We noticed a high prevalence of multidrug resistant germs (ESBL, MRSA, etc). The majority of them were involved in nosocomial surgical site and urinary tract infections.
