Microbiological characteristics of patients with positive urocultives at the hospital universitario del rio, Ecuador

Abstract

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.
