A dramatic increase in the incidence of methicillin-resistant Staphylococcus aureus at a teaching hospital was documented to be due to three factors: a hospital-wide outbreak of 32 cases caused by an epidemic strain, an increase in the number of nosocomial cases caused by several other strains, and an increase in the number of patients admitted carrying strains acquired at other institutions.
Case patients with the epidemic strain were significantly more likely than control patients to have had previous exposure to a respiratory therapist (P=.005) who had chronic sinusitis due to the epidemic strain.
The plasmid DNA of isolates from the implicated respiratory therapist and affected patients yielded the same patterns on restriction endonuclease digestion.
