Microorganismos frecuentes y resistencia antimicrobiana en muestras biológicas en el área de neonatología del Hospital Vicente Corral Moscoso 2015

Abstract

Background: The immunological immaturity of newborns involves a greater susceptibility to infections by various microorganisms, including those traditionally innocuous. Intra-hospital infections are an important cause of morbidity and mortality in neonates. Objective: Determine the frequent and antimicrobial resistance of microorganisms in biological samples of neonates in “Vicente Corral Moscoso” Hospital, during January-December 2015. Methodology: A descriptive, retrospective and observational study was conducted, based on the data from microbiology area in “Vicente Corral Moscoso” Hospital. Bacterial isolates and antimicrobial resistance in biological samples of neonatology during 2015 were examined. The development of the database and statistical analysis were done on the programs SPSS v22 and Microsoft Excel. The variables were described using frequency tables and percentages. Results: 343 medical records were analyzed, and a total of 343 microorganisms were found in 11 types of biological samples which were classified into 27 bacterial species. Klebsiella pneumoniae was the most frequent bacteria with 26.5% and the most resistant with 45.2%. A total of 2885 resistances to 37 different types of antibiotics were counted, being Ampicillin the antibiotic to which the bacteria showed greater resistance to, with 9.5%
