ABSTRACT
Aim: The present study was conducted to characterize VRSA isolates on the basis of pulsed field gel electrophoresis (PFGE) and the presence of spa gene, recovered from different Doon Valley Hospitals.Methodology: Six VRSA isolates were analyzed using PFGE and spa typing. spa gene coded Protein A was used as a genetic marker for the characterization of Staphylococcus aureus isolates. Dendrogram were constructed on the basis of unweighted pair group method with arithmetic means (UPGMA method) for clusters analyses.Results: Dendrogram finally showed two major banding patterns at about 85% similarity designated as PFGE type A and PFGE type B exhibiting differences of 4-6 bands. The length of spa gene varied from 1200 to 1500 bp, showing variation in length. The most prevalent length was 1200bp.
