A training dataset, containing 5631 isolates from the Pathogenwatch database and 181 isolates obtained in the Russian Federation during 2018\u201319, was used to build a regression model. The regression equation was tested on 14 WHO reference strains. Ceftriaxone resistance determinants for the 448 evaluated clinical isolates collected in Russia were identified using microarray analysis, and MICcro values were calculated using the regression equation and compared with those measured by the serial dilution method.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The regression equation for calculating MICcro values included 20 chromosomal resistance determinants. The greatest contributions to the increase in MICcro were shown to be PBP2: Ala-501\u2192Pro, Ala-311\u2192Val, Gly-545\u2192Ser substitutions, Asp(345\u2013346) insertion; and PorB: Gly-120\u2192Arg substitution. The substitutions PBP2: Ala-501\u2192Thr\/Val, PorB: Gly-120\u2192Asn\/Asp\/Lys and PBP1: Leu-421\u2192Pro had weaker effects. For 94.4% of the isolates in the evaluation set, the predicted MICcro was within one doubling dilution of the experimentally determined MICcro.
