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 using partial 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 group isolates in Japan.
已报道具有较低碳青霉烯类药物敏感性的 组分离株,但在日本其分离率尚不清楚。我们收集了 356 株临床甲型溶血性链球菌分离株,并通过部分测序鉴定出其中 142 株为 。美罗培南不敏感率为 17.6%(25/142)。所有 25 株碳青霉烯类药物不敏感的分离株均在 PBP1A、PBP2B 和 PBP2X 的保守基序中或附近携带氨基酸取代。日本 组分离株中碳青霉烯类药物不敏感较为常见。
