DNA fingerprinting by pulsed-field gel electrophoresis is more effective than ribotyping in distinguishing among methicillin-resistant Staphylococcus aureus isolates
1 Apr 1992
Abstract excerpt
Pulsed-field gel electrophoresis (PFGE) after SmaI restriction of DNA from 239 methicillin-resistant Staphylococcus aureus isolates (from 142 patients) produced 26 different fingerprints. The deduced chromosome sizes ranged from 2,200 to 3,100 kb (+/- 100 kb). A total of 81 isolates taken from 65 patients were then typed by PFGE and ribotyping with ClaI, EcoRI, and HindIII. Ribotypes were less discriminating than...
