^aU.K., United Kingdom; U.S., United States; Pat., patient. 

^bDates for strains isolated from patients involved in the outbreak and from surgeon A are given as month-year. 

^cThe first letter in the compound RAPD code identifies the ERIC1-ERIC2 result; the second letter identifies the RAPD1-RAPD7 score. 

^dStrain from a quality control study conducted by the Dutch Foundation for Quality Assessment of Medical Microbiological Laboratories (SKMM).
