Staphylococcus simiae sp. nov., isolated from South American squirrel monkeys.

Eight coagulase-negative, oxidase-negative and novobiocin-susceptible staphylococcal strains were isolated from the gastrointestinal tracts of South American squirrel monkeys (Saimiri sciureus L.). These strains were differentiated from known staphylococcal species on the basis of 16S rRNA gene and hsp60 gene sequencing, and from the most closely related species by using DNA-DNA hybridization, ribotyping, whole-cell protein profiles and biotyping.

Development of a PCR test for the identification of Staphylococcus intermedius based on the 16S rDNA sequence.

The development of a PCR assay based on the 16S ribosomal RNA gene (rDNA) sequence was carried out for the identification of Staphylococcus intermedius. Sixty-six strains of S. intermedius, 70 of Staphylococcus aureus and 2 of Staphylococcus hyicus were examined for the assay.

Characterization of Staphylococcus intermedius from pigeons, dogs, foxes, mink, and horses by pulsed-field gel electrophoresis.

Staphylococcus intermedius from pigeons, dogs, foxes, mink, and horses, was characterized by pulsed-field gel electrophoresis (PFGE) to evaluate the use of this typing method for discriminating among strains. SmaI cut the chromosomal DNA into 7-13 fragments ranging from approximately 48 kb to 655 kb, with most of the detectable fragments being smaller than 172 kb. S.
