Abstract
The epidemiology of methicillin-resistant Staphylococcus aureus has changed considerably over the last 3 decades, including the recognition of lineages associated with the community and with livestock exposure, in addition to nosocomial strains. A recent study by R. N. Sieber, R. L. Skov, J. Nielsen, J. Schulz, et al. (mBio 9:e02142-18, https://doi.org/10.1128/mBio.02142-18) demonstrates the importance of multisectoral cooperation at the intersection of occupational health, genomics, veterinary medicine practitioners, and farmers in order for us to better understand the epidemiology of antibiotic-resistant organisms.
Highlights
The epidemiology of the opportunistic pathogen Staphylococcus aureus has changed substantially over the last 3 decades
S. aureus was originally considered a hospital-associated organism, but new classes of strains that emerged outside of the hospital setting were identified in the 1990s and in the 2000s
The latter was first associated with a single multilocus sequence type, ST398, and other closely related strains within clonal complex 398 (CC398)
Summary
The epidemiology of the opportunistic pathogen Staphylococcus aureus has changed substantially over the last 3 decades. The application of whole-genome sequencing (WGS) has enabled better understanding of the potential origins of CC398 [4], and in the study discussed here, Sieber et al [5] have applied this tool to better understand how animal movement within the Danish pig production system drives the spread of CC398.
