A method for distinguishing among Pseudomonas aeruginosa strains using rand
om amplified polymorphic DNA (RAPD) typing was evaluated for reproducibilit
y and discriminatory power. A total of 200 isolates, blinded in triplicate,
were evaluated by RAPD. All 600 samples were typeable; 197 of 200 isolates
gave identical results on all three occasions, and 131 distinct RAPD types
were identified.
