title: Staphylococci Related to Farm Ostriches and Their Sensitivity to Enterocins.
abstract: In Slovakia, ostriches are reared mainly for their meat. There is still limited information related to microflora of ostriches, including staphylococci. Knowing the composition of microflora is very important for the recognition of potential pathogenic agents. Recently, a frequent problem in animals is the occurrence of bacteria resistant to antibiotics. The aim of this study was to detect staphylococcal species in feces of farm ostriches and to test their sensitivity to antibiotics and enterocins. Altogether 140 ostriches from three age groups were sampled (n = 18, faecal mixture samples from each group) on a farm in Slovakia or on Slovak farm. From 54 fecal samples, the staphylococcal count reached an average 4. 3 ± 0. 63 (log10) CFU/g. Twenty-four lactic acid producing strains were taxonomically classified to eight species of the genus Staphylococcus: Staphylococcus equorum, S. xylosus, S. epidermidis, S. haemolyticus, S. cohnii, S. succinus, S. warneri, and S. hominis. Strains were evaluated by secure probable species identification/probable species identification (score value up to 2.299) confirmed also by phenotypization. Most strains were sensitive to antibiotics. Four strains (S. haemolyticus SHae 111, S. haemolyticus SHAe 371, S. xylosus SX 2133, and S. warneri SW 292) were resistant to methicillin but sensitive to six or five of the seven enterocins tested (inhibitory activity 200-12,800 AU/mL). S. warneri SW 292 was sensitive to all enterocins (activity up to 12,800 AU/mL).
