Abstract / Zusammenfassung

Background and objectives:
Staphylococcus aureuscan colonize humans and animals and plays an important role as zoonotic pathogen. During recent years, numerous studies focused on staphylococci from humans and animals including zoo and wildlife species. The aim of the present study was to investigate the resistance properties ofS. aureus isolates from naked mole rats (Heterocephalusglaber) kept in captivity.

Material and methods:
In total, eightS. aureusisolates from five individuals were cultured from bite wound abscesses.They were investigated for their enzymatic properties and identified by MALDI-TOF MS and spa typing. Antimicrobial susceptibility testing for 31 antimicrobial agents was performed by broth microdilution. Specific resistance genes were investigated by PCR.

Results:
All isolates were coagulase and hyaluronidase positive. Two spa types t6544 (n=5) and t7200 (n=3) were detected, differing in a duplication of r12 in t7200. Susceptibility testing revealed that all isolates were resistant to penicillin and ampicillin and harbored the β-lactamase gene blaZ. The three isolates with spa type t7200 were additionally resistant to tetracycline. Two isolates were positive for the tet(K) gene, while the remaining isolate harbored thetet(L) gene.

Conclusion:
The isolates from naked mole rats displayed two related spa types and only limited resistance properties. This is a favorable situation regarding a possible zoonotic transmission between animals and humans.
