Our current knowledge of microbiota in wild ruminants is limited. The goal of this study was to evaluate staphylococcal species in red and roe deer for various attributes (haemolysis, DNase, and urease activities; lactic acid and biofilm production; and antibiotic profile) and their susceptibility to gallidermin. Sixteen staphylococcal strains were identified from faeces of 21 free-living animals (9 adult female Cervus elaphus—red deer and 12 young female Capreolus capreolus—roe deer) sampled by the Polish colleagues in the Strzałowo Forest District, Piska Primaeval Forest. The variability in the species of staphylococci was determined. Seven species (Staphylococcus capitis, S. epidermidis, S. haemolyticus, S. hominis, S. pseudintermedius, S. vitulinus and S. warneri) and five clusters/groups of coagulase-negative staphylococci (CoNS) were identified. The strains were generally not haemolytic and Dnase negative; did not form biofilms or only produced low-grade biofilms; exhibited high levels of lactic acid; were urease positive; and were generally susceptible to antibiotics (only two strains were resistant to multiple antibiotics). However, all of the strains were susceptible to the lantibiotic bacteriocin gallidermin, with a minimal inhibitory concentration of 0.0156 μg (up to 6400 AU/ml in arbitrary units). This is the first study to perform a detailed study of the properties of CoNS from roe and red deer.
