摘要
产OXA-244大肠埃希菌（OXA-244-Ec）已在欧洲传播，主要是在社区。在波兰，它自 2017 年开始传播，尤其是在 2023 年，但与其他国家不同的是，迄今为止所有分离菌株都是在医院中发现的。这些分离物（n = 101）代表了不同地区的一次大规模爆发和两次有限爆发，以及多种在流行病学和基因上不相关的生物体。OXA-244-Ec 群体由 14 个 ST 组成，其中以 ST38 为主。ST38 分离物属于两个主要菌系--A 群和 B 群，是两起医院疫情的罪魁祸首。有必要加强对 OXA-244-Ec 的监测，并提高警惕。
Several epidemic and multiple sporadic genotypes of OXA-244-producing Escherichia coli in Poland; predominance of the ST38 clone.
OXA-244-producing Escherichia coli (OXA-244-Ec) has disseminated in Europe, mostly in the community. In Poland it has spread since 2017, especially in 2023, but in contrast to other countries, all isolates have been identified in hospitals so far. The isolates (n = 101) represented one large and two limited outbreaks in different regions, and multiple epidemiologically and genetically non-related organisms. The OXA-244-Ec population consisted of 14 STs, with ST38 dominating. The ST38 isolates belonged to two major lineages, Clusters A and B, responsible for two of the hospital outbreaks. Enhanced concern and vigilance are necessary in the OXA-244-Ec surveillance.
