The aim of the RESOURCE study was to determine the antimicrobial resistance profile of gram-negative bacteria isolated from outpatient urine samples collected across the Russian Federation.MethodsA total of 96,781 urine samples were collected from 520 cities of the Russian Federation between January 1 and December 31, 2017. Antibiotic susceptibility was performed using semi-automated analysers. The mean age of the study population was 40.9 years, 80.2% were female and 19.8% were male.FindingsOf the uropathogens isolated, 64.2% were gram-negative bacteria. Among these, Escherichia coli was the most common (49.1%), followed by Klebsiella pneumoniae (9.5%), Proteus mirabilis (2.9%), Pseudomonas aeruginosa (1.7%) and Enterobacter spp. (1.0%). Of the antibiotics tested, 50% of the isolated E. coli strains were resistant to ampicillin, followed by co-trimoxazole (30.3%), aztreonam (26.2%), levofloxacin (28.8%) and cefuroxime (21%). Conversely, E. coli were highly susceptible to imipenem (0.7% resistant strains isolated), amikacin (0.9%), nitrofurantoin (4.5%) and fosfomycin (1.2%)...
