PREVALENCIA DE RESISTENCIAS DE BACTERIAS AISLADAS EN HEMOCULTIVOS, EN UN HOSPITAL UNIVERSITARIO DE COLOMBIA RESISTENCIAS DE BACTERIAS AISLADAS EN HEMOCULTIVOS

Objective: to describe the frequency of microorganisms and the antibiotic resistance of isolated bacteria in blood cultures of patients with bacteremia, in a university hospital in Colombia. Methods: An observational, descriptive and cross-sectional study was developed in individuals older than 18 years, where the positive blood cultures were described, isolated in all the services of the University Hospital of the Caribbean. Results: Of the 211 blood cultures analyzed, 53.1% were men. The Gram-positive microorganisms correspond to 49.8%, with a high frequency of S. aureus in 16.1%. Of the Gram negative microorganisms, E.coli was isolated by 18%. Vancomycin resistance was established at 4.4%. K. pneumoniae showed resistance to meropenem in 15.3% of cases. E.coli, P. aeruginosa and E. cloacae are sensitive to carbapenes. Thus, in our study, the bacteria most frequently isolated in the blood cultures were predominantly Gram negative, with resistance to carbapenes for some strains of K. pneumoniae.
