Unmasking Methicillin-resistant Staphylococcus argenteus: pathogenic potential, diagnostic pitfalls and antibiotic resistance of MRSArg in Norway 2008-2019.

ABSTRACT:

Background

Staphylococcus argenteus is a coagulase-positive species within the Staphylococcus aureus complex that may carry the mecA gene, conferring methicillin resistance. Despite its clinical relevance, methicillin-resistant S. argenteus (MRSArg) remains underreported and poorly characterized in many regions.

Aim

This study presents the first nationwide analysis of MRSArg in Norway, detected among MRSA 18,152 isolates submitted to the Norwegian MRSA Reference Laboratory between 2008 and 2019.

Methods

Clinical and epidemiological data were retrieved from national surveillance systems and laboratory records, enabling classification into healthcare- and community-associated categories. A representative panel of MRSArg genotypes (n =
