Objective. To evaluate antimicrobial resistance patterns of clinical Haemophilus influenzae isolates from different regions of Russia during 2014–2017.
Materials and Methods. We included in the study 185 clinical H. influenzae isolates from 13 Russian cities. Susceptibility testing was performed by reference broth microdilution method (ISO 207761:2006). Susceptibility testing results were interpreted using EUCAST v. 10.0 breakpoints.
Results. H. influenzae isolates were highly susceptible to all (96.8%-100%) β-lactams tested (amoxicillin/ clavulanate, cefixime, ceftaroline, ceftibuten, cefditoren, ertapenem) with the exception of ampicillin (15.
