ABSTRACT Whole-genome analysis by 62-strain microarray showed variation in resistance and virulence genes on mobile genetic elements (MGEs) between 40 isolates of methicillin-resistant Staphylococcus aureus (MRSA) strain CC22-SCCmecIV but also showed (i) detection of two previously unrecognized MRSA transmission events and (ii) that 7/8 patients were infected with a variant of their own colonizing isolate.

    ABSTRACT: Investigation of S. aureus outbreaks, and particularly those due to methicillin-resistant S. aureus (MRSA) in hospitals, can identify infection reservoirs and prevent further colonization and infection. During outbreaks, S. aureus genomes develop single nucleotide polymorphisms (SNPs), small genetic rearrangements, and/or acquire and lose mobile genetic elements (MGE) encoding resistance and virulence genes. Whole genome sequencing (WGS) is the most powerful method for discriminating between related isolates and deciding which are involved in an outbreak. Isolates with only minor variations are detectable and can identify MRSA transmission routes and identify reservoirs. Some patients may carry 'clouds' of related isolates, and this has consequences for how we interpret the data from outbreak investigations. Different clones of MRSA are evolving at different rates, influencing their typability. S. aureus genome variation reveals the importance of antibiotic resistance in the long term evolution of successful hospital clones, contributing to strategies to prevent the spread of successful MRSA clones.

    ABSTRACT: In many parts of the world, MRSA are responsible for a high proportion of S. aureus infections in patients in contact with healthcare. Molecular studies have shown this is due to one or more MRSA clones that have become endemic in each hospital or healthcare facility, resulting in hospital- or healthcare-associated MRSA (HA-MRSA). The infection rate and clones responsible for HA-MRSA can vary substantially in different geographical locations. Molecular methods have allowed clones to be categorized, as well as the opportunity to track the evolution and spread of clones in healthcare settings and around the world. The genomes of HA-MRSA isolates belonging to the same clonal group can show dramatic variability particularly in the carriage of mobile genetic elements (MGEs) encoding virulence and resistance genes. HA-MRSA are potentially resistant to all classes of antibiotics, although individual isolates that are fully drug resistant are not reported. The incidence of fluoroquinolone resistance in HA-MRSA is remarkably high, suggesting use of this class of antibiotics as well as the β-lactams contributes to the selection and success of HA-MRSA clones in the hospital setting.
