Background. P. aeruginosa, one of the main opportunistic nosocomial pathogens, causes infections with high rates of morbidity and mortality. Objectives. To determine the frequency of antibiotic resistance in isolates of P. aeruginosa causing bacteremia during the periods 2008-2010 and 2017-2019. To determine the frequency of carbapenemase production in isolates of P. aeruginosa resistant or with intermediate susceptibility to any carbapenem in both periods. Materials and methods. Descriptive study combining secondary data analysis and experimental work. To describe the percentages of antibiotic resistance of P. aeruginosa in the indicated periods, data from studies that collected isolates from bacteremia patients in different hospitals in Peru were used. In stored isolates of P. aeruginosa resistant or with intermediate susceptibility to any carbapenem, phenotypic procedures (mCIM and eCIM) were developed for the detection of carbapenemase production. Results. The observed percentages of antibiotic resistance in P. aeruginosa isolates from the first period exceeded those of the second period overall. In 2008-2010, 18 isolates producing carbapenemases (14.9%) and 5 producers of metallo-β-lactamases (MBL) (4.1%) were identified. In 2017-2019, 5 isolates producing carbapenemases (20%) and no MBL were identified. The studied isolates were mainly obtained from patients hospitalized in Intensive Care Units (ICU) and Medicine services. Conclusions. The frequency of antibiotic resistance in the first period was higher than that in the second. The percentage of detection of carbapenemases among P. aeruginosa isolates not susceptible to at least one carbapenem increased from one period to another.
