Article Synopsis
- A study in Spain analyzed the rise of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) from 2004 to 2012, revealing a notable increase in cases over time.
- 246 of the 8326 MRSA strains studied were identified as CA-MRSA, with a significant rise from 0.43% in 2004-2007 to 5.44% in 2008-2012.
- The majority of CA-MRSA strains were PVL-positive, particularly the ST8-IVc clone, along with the emergence of the USA300 and pig-associated ST398-V clones, reflecting a diverse genetic landscape of these bacteria.
Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the mecC gene have been reported from humans and animals from several European countries, but never from Spain. We describe the first isolates of mecC-positive MRSA of human origin collected in Spain and report a fatal case of bacteraemia.
Methods: Isolates were tested for phenotypic resistance using cefoxitin, tested for the mecA/mecC genes and toxin genes by PCR, and typed by staphylococcal cassette chromosome mec (SCCmec), PFGE, spa, multilocus sequence typing and agr.
In a point-prevalence study performed in 145 Spanish hospitals in 2006, we collected 463 isolates of Staphylococcus aureus in a single day. Of these, 135 (29.2%) were methicillin (meticillin)-resistant S.

Methods: The distributions of molecular markers, including antibiotic resistance genes, were investigated in 203 S. aureus, comprising 90 methicillin-resistant S.
Introduction: Since 1986 we have carried out five nationwide point-prevalence studies in Spain analyzing Staphylococcus spp. The 2006 data, corresponding to the sixth study, are presented herein.
Methods: A total of 145 hospitals from all geographic areas of the country participated in the study.
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) isolates producing the Panton-Valentine leukocidin (PVL) have been reported worldwide. We describe the molecular characteristics of PVL-positive CA-MRSA strains isolated in Madrid, Spain, and analyze the clinical features of patients infected with these isolates. From 2004 to 2007, we collected 13 PVL-positive MRSA isolates from patients attending to the emergency department.
