Characterization Antibiotic resistant bacterial strains from isolates from critical areas of a hospital in Guayaquil

Abstract

Introduction: Evidence is plentiful on the increasing resistance to antibiotics as a world health problem, which has an important impact on hospitalised patients and healthcare systems. Materials and Methods: this is an exploratory, retrospective study, based on the WHONET database of a hospital in the city of Guayaquil, which aims to analyse the microorganisms detected with reported antimicrobial resistance. Microorganisms with resistance to methicillin or vancomycin were not included in this study, only resistance to 3rd and 4th generation cephalosporins, carbapenemase-producing strains, KPC strains, multidrug-resistant strains and colistin-resistant strains. Results: among the resistance patterns analysed, resistance to 3rd and 4th generation cephalosporins reached 68%, followed by carbapenemase production (17%). Conclusions: antibiotic resistance is a growing problem that requires further research in different countries, in order to implement studies that allow interventions in different sectors, with the aim of reducing resistance, promoting programmes for rational use of antimicrobials, and reducing health care costs.
