Identification of Staphylococcus spp. by PCR-restriction fragment length polymorphism analysis of dnaJ gene.

ABSTRACT: A PCR-restriction fragment length polymorphism (RFLP) analysis method that analyzes a part of the dnaJ gene was designed for the rapid and accurate identification of Staphylococcus spp. XapI or Bsp143I digestion of the PCR-generated products rendered distinctive RFLP patterns that allowed 41 reference species and subspecies to be identified with a high degree of specificity. The novel method was validated by the identification of 23 clinical staphylococcal strains, and the results were compared with those obtained by other genotypic identification methods. A 100% concordance of the results was shown. Therefore, PCR-RFLP analysis of the dnaJ gene is proposed as a reliable and reproducible method for the identification of Staphylococcus spp.
