Rate of nosocomial MRSA transmission evaluated via contact screening.

Background: The prevention of methicillin-resistant S. aureus (MRSA) transmission in the healthcare setting is a priority in Infection Control practices. A cornerstone of this policy is contact tracing of nosocomial contacts after an unexpected MRSA finding.

Livestock-associated methicillin-resistant epidemiology, genetic diversity, and clinical characteristics in an urban region.

Objectives: While Livestock-associated methicillin-resistant (LA-MRSA), defined as CC398, is a well-known pathogen among those working with livestock, there are indications that LA-MRSA prevalence among the general population is increasing. However, the clinical impact in urban areas remains unknown. The aim of this study was to assess the genetic epidemiology and clinical characteristics of LA-MRSA in an urban area with a limited livestock population.

Hospital transmission of borderline oxacillin-resistant evaluated by whole-genome sequencing.

is a major cause of hospital infections worldwide. Awareness towards methicillin-resistant (MRSA) infections is high but attention towards borderline oxacillin-resistant (BORSA) is limited, possibly due to an underestimated clinical relevance, presumption of low incidence and diagnostic limitations. BORSA surveillance has not been routinely implemented, and thus consensus with regard to a definition and infection control measures is lacking.
