Abstract
DIAZ-TELLO, José; ROJAS-JAIMES, Jesús; IBARRA-TRUJILLO, Jimmy and TARRAGA-GONZALES, Delza. Antimicrobial sensitivity of the environmental microbiota in the intensive care units of a peruvian hospital. Rev. perú. med. exp. salud publica [online]. 2017, vol.34, n.1, pp.93-97. ISSN 1726-4634. http://dx.doi.org/10.17843/rpmesp.2017.341.2709.
The objective was to detect Gram-negative bacilli and Gram-positive cocci isolated from the environmental microbiota of the Intensive Care Unit (ICU) departments of Neonatology, Pediatrics, and Transplants (kidney, liver, and general) in a Lima hospital and determine their antimicrobial sensitivity. Eighty samples were obtained from inanimate surfaces using a wet swab. A total of 61 bacterial strains were identified, including Staphylococcus epidermis (46.0%), Alcaligenes sp. (21.3%), Pseudomonas aeruginosa (16.4%), Acinetobacter sp. (13.1%), Staphylococcus aureus (1.6%), and Staphylococcus haemolyticus (1.6%). Acinetobacter sp. and P. aeruginosa showed a heightened sensitivity to the antibiotics assessed, while Alcaligenes sp. and S. epidermidis presented the highest antimicrobial resistance. It is recommended that sustained asepsis and monitoring methods be used in ICUs.
