Resumen
La Pseudomona aeruginosa tiende a desarrollar fenotipos de multirresistencia que junto a la adquisición de la morfología mucoide y la capacidad de formar biopelículas en la mayoría de las superficies biológicas y abióticas, lo cual le brinda ventajas para incrementar sus niveles de resistencia a los antibióticos, sin embargo a pesar de la importancia de este problema son pocas las investigaciones sobre este tema a nivel nacional y regional. Se determinó la susceptibilidad antimicrobiana de Pseudomona aeruginosa en el Hospital Isidro Ayora de la ciudad de Loja, para lo cual se aislaron e identificaron quince cepas de P. aeruginosa, de un total de cien pacientes, muestras que fueron procesadas en Laboratorio San Gabriel, en el que se utilizaron diferentes parámetros como la observación de la morfología de las colonias, reacción de citocromo oxidasa y catalasa; seguidamente se realizó la prueba de sensibilidad a los antimicrobianos de forma automatizada en el MicroScan, usando doce antibióticosantipseudomónicos. En cuanto a los resultados de la presente investigación la susceptibilidad de Pseudomonas aeruginosa oscila entre 46,66% y 86,66% de los doce antibióticos usados, siendo el imipenem y el meropenem, quienes tienen una mayor susceptibilidad.

Antimicrobial susceptibility of Pseudomonas aeruginosa was determined in the Isidro Ayora Hospital in the city of Loja, for which they were isolated and identified fifteen strains of P. aeruginosa, a total of one hundred patients, samples were processed in laboratories San Gabriel, in the different parameters such as observation of colony morphology, reaction of cytochrome oxidase and catalase were used; then test antimicrobial susceptibility automated way the MicroScan was conducted using twelve-antipseudomónicos antibiotics. As for the results of this study the susceptibility of Pseudomonas aeruginosa between 46.66% and 86.66% for the twelve antibiotics used, with imipenem and meropemen who have increased susceptibility.
