Summary: The use of antimicrobial agents contributes to the spread of antimicrobial resistance which becomes a serious threat affecting both human and animal health. In our study, 117 coagulase-positive (43.2%) and 154 coagulase-negative staphylococci (56.8%) isolated from hares (Lepus europaeus) hunted in North-East Austria, farm pheasants (Phasianus colchicus), mechanically separated poultry (MSP) and deep-frozen poultry (originating in the region of East Slovakia) have been tested for their susceptibility to ten antibiotics by disk diffusion test. The results demonstrate that resistance to at least one antibiotic was found in the majority (72.3%) of staphylococcal isolates tested. The highest number of resistant strains (85.0%) was detected in farm pheasants. In general, staphylococcal isolates were often resistant to penicillin (27.7–52.8%) and ampicillin (19.6–55.6%), although resistance to erythromycin in farm pheasants (48.3%) and resistance to novobiocin in deep-frozen poultry predominated (41.2%). However, methicillin/oxacillin-resistant strains were detected in a much lower frequency (6.5–20.8%). Most strains were simultaneously resistant to 2 antibiotics (29.2% isolates from hares; 31.7% from pheasants; 37.6% from MSP and 15.2% from deep-frozen poultry), but multiresistance was also detected in several strains (7.4%). The most effective antibiotic was vancomycin, to which no staphylococcal isolate was resistant.
