Resumo(s)

A methicillin-resistant Staphylococcus aureus CC398 was recovered from a wild female boar (Sus scrofa) in the north of Portugal, in 2013 (Sousa et al. 2017). Whole genome sequencing (WGS) revealed this strain carries a new variant of a mecA-containing staphylococcal chromosomal gene cassette (SCCmec) type IV with an uncommon J3 region. WGS studies can facilitate surveillance and provide more detailed characterization of bacterial clones circulating in the wild, reinforcing the need for a one health perspective to better understand and control antimicrobial resistance.

Highlights: New SCCmec type IV J3 variant; Wild boars vectoring antimicrobial resistance; MRSA CC398 whole genome sequencing; MRSA CC398 antimicrobial resistance in silico analysis.
