Streptococcus mitis/oralis group isolates with reduced carbapenem susceptibility have been reported, but its isolation rate in Japan is unknown. We collected 356 clinical α-hemolytic streptococcal isolates and identified 142 of them as S. mitis/oralis using partial sodA sequencing. The rate of meropenem non-susceptibility was 17.6% (25/142). All 25 carbapenem-non-susceptible isolates harbored amino acid substitutions in/near the conserved motifs in PBP1A, PBP2B, and PBP2X. Carbapenem non-susceptibility is common among S. mitis/oralis group isolates in Japan.
