To determine antimicrobial susceptibility and molecular characteristics of mecC-carrying methicillin-resistant Staphylococcus aureus (MRSA) and non-S. aureus staphylococci isolated from wildlife.
Analyzed five oxacillin-resistant S. aureus isolates and one coagulase-negative Staphylococcus isolate that were negative for mecA by conventional PCR.
Performed mecC and Panton-Valentine leucocidin PCR, spa typing, multilocus sequence typing, SCCmec typing, and 16S rDNA sequence analysis alongside antimicrobial susceptibility testing.
All five MRSA isolates carried mecC and SCCmec type XI, lacked PVL genes, were resistant exclusively to β-lactams, and belonged to ST130 (spa types t843, t10513, t3256) or ST2620 (spa type t4335).
The non-S. aureus isolate was closely related to Staphylococcus stepanovicii and harbored mecA and blaZ genes linked to SCCmec XI.
Findings mark the first identification of mecC-positive MRSA in a European otter and European brown hare, and the first methicillin-resistant non-S. aureus isolate in a Eurasian lynx.
