Fifty-five methicillin-resistant Staphylococcus aureus (MRSA) isolates
collected at New York Hospital Medical Center of Queens in 1989 were
analyzed by molecular fingerprinting techniques. Close to 70% of these
isolates (38 of 55) shared a common pulsed-field gel electrophoretic
pattern, carried the same mecA gene polymorph type II, were free of the
transposon Tn554, and would not react with a mecI-specific gene probe. An
additional five isolates shared all properties of the major MRSA clone
except that they carried mecA gene polymorph type III. All these isolates
had an extremely heterogeneous methicillin resistance phenotype that
belonged to population analysis profile class 1 or 2. The rest of the 12
MRSA isolates showed a variety of chromosomal pulsed- field gel
electrophoretic patterns that carried different mecA polymorphs and that
also gave positive reactions with DNA probes for Tn554 and for the mecI
gene. The molecular features of the majority MRSA clone suggest that it is
an archaic MRSA isolate similar in features to early MRSA isolates
recovered in the 1960s.
