Bacteria Resistances in Positive Urine Cultures from a Tertiary Care Hospital in Western Part of Romania – a Cross-Sectional Study

Background/Objectives: Urinary tract infections represent a global problem with implications on mortality and morbidity. Published data present different bacterial incidence and different antibiotics resistances. With this study, we aimed to evaluate bacteria distribution and antibiotic resistance in a tertiary care hospital from the Western part of Romania. Methods: we evaluated all the positive urine culture from the year 2021 from the Emergency County Hospital “Pius Brinzeu” from Timisoara, Romania. We evaluated 1264 urine cultures and identified the following bacteria: Escherichia Coli, Klebsiella spp, Proteus spp., Pseudomonas auruginosa, Staphylococcus aureus, Enteroccocus spp., Enterobacter spp., Acinetobacter baumanii, Providencia spp., Corynebacterium spp. Results: Median age was 67 with 65.6% females. Diabetes mellitus incidence was 12%. Most common bacteria was E. coli – 44.1%, followed by Enterococcus spp. – 17.1%, Klebsiella spp. -15.7% and Proteus spp. – 5.4% E. coli presented the highest resistance rate to amoxicillin-clavulanic acid (50%), Enterococcus spp. to ciprofloxacin (71.3%), Klebsiella spp. to piperacillin-tazobactam (43.3%) and Proteus spp. to trimetroprime-sulfometoxazole (33%). The highest incidence of MDR bacteria was among Acinetobacter baumanii (40%), followed by MRSA (31.8%) and Klebsiella spp. (25.3%). Conclusions: Bacteria distribution is similar in all the Romanian regions among the positive urine cultures. Antibiotics resistance differ among regions and the MDR bacteria incidence is rising.
