Introduction: Nosocomial infections produce high mortality rates and increase health care costs. One of the main problems presented by nosocomial infections is multiresistant microorganisms. Material and methods: A multicentric epidemiological study was performed in several hospitals in Mexico to know the resistance of those microorganisms causing epidemiologically relevant infections; here, we present the preliminary report of three of them. The information of each participating hospital was concentrated in databases for its statistical analysis. Results: Five hundred sixty-three records of infections were obtained, of which 477 isolates were registered: 55% (310) were gram-negative bacilli, 27% (154) were gram-positive bacilli, 2.3% (13) were fungi; non isolates were found in 15.2% (86). Pseudomonas aeruginosa was the bacteria with more isolates, 24% (115), followed by Acinetobacter baumannii, 12.5% (60), and Staphylococcus aureus, 9% (43). Discussion: The importance of performing these multicentric studies in Mexico is to make clear the local status of bacterial resistances and be able to evaluate the multiresistance panorama. Conclusions: Multi-year multicenter studies help to assess and compare the local epidemiology of each hospital and monitor the resistance of microorganisms to frequently used antibiotics in order to detect the emergence of multiresistant strains. It is advisable to perform a molecular biological analysis to define the phenotype and genotype of each bacterium and, thus, know the genetic information about possible new forms of bacterial resistance.

Key words: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and species of Enterobacteriaceae, nosocomial infections, multiresistance, multidrug resistance.
