*Antimicrobial agents tested: chloramphenicol, clindamycin, erythromycin, penicillin G, tetracycline, vancomycin.
†Entries represent putative genetic relatedness to the case-patient no. 1 strain A based on SmaI and SfiI DNA restriction patterns by using categories as defined by Tenover et al. (5). The results obtained with Sfi I correlated completely with the results obtained with SmaI; PFGE, pulse-field gel electrophoresis; OF, opacity-factor.
§Specimen B was nontypable with SmaI but was typable with SfiI.
