Objective. To study the antimicrobial susceptibility profile of Moraxella catarrhalis isolates from different regions of Russia in 2010–2021. Materials and Methods. The study included 352 isolates of M. catarrhalis isolated in 11 cities of Russia (Volgograd, Irkutsk, Kazan, Kirov, Moscow, Murmansk, Perm, Seversk, Togliatti, Tomsk, and Ulan-Ude) in 2010–2021. Identification was done by MALDI-TOF mass spectrometry. Antimicrobial susceptibility testing was determined by broth microdilution method in accordance with the ISO 20776-1:2020.
