Emergence of MRSA ST630/spa type t4549 in Denmark and other nordic countries
Methicillin-resistant Staphylococcus aureus of sequence type 630 (ST630) and spa type t4549 is an emerging cause of infections in humans in Asia and since 2015 also in the Nordic countries including Denmark, where this lineage was among the most important community associated MRSA lineages in 2018. In this study, the emergence of MRSA ST630/t4549 in Denmark and other Nordic countries was investigated by comparative genomics in order to understand the recent emergence of this lineage in this area of generally low MRSA prevalence.
