Objective: To evaluate the microbiological characteristics of patients with positive urine cultures at the Hospital Universita-rio del Rio, Ecuador. Materials and methods: An observational, retrospective, and descriptive study was carried out in patients undergoing a urine culture, in the microbiology service in In-tensive Care Unit (ICU) for adults, pediatric ICU, outpatient, and hospitalization service during 2018, the clinical data were obtained of the medical records department. Results: Of the 395 positive reports, the most common germs among the gram negative were Escherichia coli with 69.6% (n=275), among the gram positive Enterococcus faecalis with 3% (n=12), and among the fungal agentes Candida albicans with 6.3% (n=25). Regarding antimicrobial resistance, gram negative germs were mainly resistant to quinolones (47.8%; n=161) and cephalo-sporins (26.4%; n=89), the most common resistance markers being resistance to quinolones (33.5%; n=113) and extended spectrum beta-lactamases (ESBL) (19.9%; n=67). On the other hand, gram positive germs were mainly resistant to oxacillin (20%; n=5), the most common resistance markers being resistance to quinolones (36%; n=9) and Staphylococcus methicillin resistance (20%; n=5). Conclusion: The microbiological reports at the Hospital Universitario del Río, Ecuador, were predomi-nantly in women, in subjects older than 20 years of age, and with outpatient management; Escherichia coli, Enterococcus faecalis, and Candida albicans were the most frequently iso-lated germs, with a high resistance to quinolones.

INTRODUCTION. – Urinary tract infection (UTI) is the process of colonization of microorganisms that invade the sterile areas of the genitourinary device of the patient, affects not only pediatric populations but also adults. For its identification, there are several tests: EMO, Gram staining, urine culture, and antibiogram, the Gold Standard being the urine culture accompanied by the antibiogram. GENERAL OBJECTIVE. – Determine the prevalence of microorganisms present in positive urine cultures and their susceptibility profile in patients who attend at Río University Hospital. METHODOLOGY. – A retrospective cross-sectional descriptive study was carried out, whose universe consisted of 1.392, and the sample was propositional. The data was collected using a collection instrument (application form). Subsequently, the results were analyzed and tabulated through the statistical software IBM SPSS version 22 and Microsoft Excel 2016. RESULTS. – According to reports from the microbiology service during 2018, 28 % urine cultures were positive, of which the main microorganisms were: Escherichia coli 69.62 %, Enterococcus faecalis 3.03 % and within the Candida albicans 6.33 % fungi. 16.32 % of the Escherichia coli isolates were producers of extended-spectrum betalactamases and 31.75 % resistant to quinolones. 26.3 % of the positive reports corresponded to the female sex between 20 and 39 years. Concerning hospital service, a prevalence of 80 % in outpatients is evidenced. CONCLUSIONS. – Positive reports mainly affected women in 80.8 % of cases. The uropathogens most affected were Escherichia coli, Klebsiella spp, and were found resistance markers: ESBL, KPC, AMPc, MRS, and resistance to quinolones.
