The aim of this study was to trace the dynamic changes of methicillin-resistant Staphylococcus aureus (MRSA) lineages in the local hospital in both the national and international context. We describe genotypic and phenotypic characterization of 62 non-duplicate MRSA isolates collected during 2010-2016 at University Hospital in Hradec Kralove, Czech Republic. The isolates were characterized by multilocus sequence typing (MLST), spa typing, and staphylococcal cassette chromosome mec typing (SCCmec typing). Eight different genotypes were described; ST225-t003-II (32/62, 52%), ST5-t002-II (13/62, 22%), and ST225-t014-II (12/62, 21%) were constantly detected over the 7-year follow-up period. The genotypes ST225-t151-II, ST225-t1282-II, ST225-t1623-II, ST78-t2832-II, and ST225-t8799-II occurred only once in the period reported. The majority of the strains, represented by ST225, belonged to clonal complex 5 (CC5).

捷克共和国大学医院血液培养物中耐甲氧西林金黄色葡萄球菌分离株的流行病学特征。

这项研究的目的是在国家和国际背景下追踪当地医院耐甲氧西林的金黄色葡萄球菌(MRSA)谱系的动态变化。我们描述了在2010-2016年间在捷克共和国赫拉德茨·克拉洛韦的大学医院收集的62个非重复MRSA分离株的基因型和表型特征。通过多基因座序列分型(MLST),spa分型和葡萄球菌盒式染色体mec分型(SCCmec分型)对分离物进行了表征。描述了八种不同的基因型。在过去7年中不断检测到ST225-t003-II(32/62,52%),ST5-t002-II(13/62,22%)和ST225-t014-II(12/62,21%)随访期。基因型ST225-t151-II,ST225-t1282-II,ST225-t1623-II,ST78-t2832-II和ST225-t8799-II在所报告的时期内仅发生过一次。
