KENNEDY-CUEVAS, Cristel Iona e ESTIGARRIBIA-SANABRIA, Gladys Mercedes. Antimicrobial resistance profile of samples with Klebsiella pneumoniae from an Intensive Care Unit in Paraguay. Infect. [online]. 2021, vol.25, n.2, pp.84-88. Epub 10-Maio-2021. ISSN 0123-9392. https://doi.org/10.22354/in.v25i2.924.
Introduction:
Klebsiella pneumoniae produces enzymes such as Extended Spectrum Betalactamases (ESBL) and Carbapenemases. These enzymes have implica tions in Intensive Care Units (ICU), because they enable the survival of bacterial species under unfavorable conditions and, therefore, facilitate their permanence in the hospital environment. There is evidence of the presence of Klebsiella pneumoniae in the ICU, in samples from: patients, health staff, room, sink, and nutri tional formulas.
Objective:
To evaluate the resistance profile of Klebsiella pneumoniae isolates in an ICU in Paraguay.
Material and methods:
descriptive, observational, cross-sectional study. 200 samples were collected (124 enteral formulas, 40 ambient and 36 patients).
Variables analyzed:
sample origin, presence of the germ, enzyme production and resistance profile.
Results:
Klebsiella pneumoniae was isolated in 14% of the samples. The germ was identified in: 25% patients, 12.9% enteral formulas and 7.5% environment. Pro duction of ESBL was observed in 85.7% of the strains, with identical resistance profiles, and production of carbapenemases in 14.3% of the strains, with different resistance profiles.
Conclusion:
the presence and resistance profiles of Klebsiella pneumoniae in the three classes of samples studied, suggest transfer of resistance genes and disse mination of the germ in ICU.
