Phenotypic and genotypic identification of staphylococci isolated from wild small mammals.

229 strains of Staphylococcus isolated from the intestines of wild small mammals (Insectivora and rodents) were analysed by phenotypic tests and 16S-23S rDNA intergenic spacer PCR amplification (ITS-PCR). Based on the results of three methods (phenotypical tests, API numerical profiles and ITS-PCR) 65.5% of all staphylococcal strains could be identified. The remaining strains were compared by cluster analysis with reference and identified strains. It is quite possible that, a part of unidentified strains represent hitherto undescribed species, all the more as their ITS types were not found among other members of the genus Staphylococcus. Moreover, the results show that small mammals provides a suitable new habitat for certain staphylococci.
