Population diversity of Staphylococcus intermedius isolates from various host species: typing by 16S-23S intergenic ribosomal DNA spacer polymorphism analysis.

Twelve 16S-23S ribosomal DNA intergenic spacer (ITS-PCR) types were identified among 57 Staphylococcus intermedius isolates from humans and other animals. Six ITS-PCR types were host specific, and most human and canine strains belonged to the same types (A and J). Pigeon, horse, and mink strains appeared more heterogeneous.
