Clustering of multiple endemic strains of methicillin-resistant Staphylococcus aureus in a nursing home: an 8-year study.
PFGE was performed on residents' first clinical MRSA isolate (n=94) during 8 years. Sixty-one percent of the isolates were clustered in time (P < .05) and space (P < .05) (i.e., 2 separate statistically significant tests). Isolates from individual units were genetically related, with only the occasional unrelated isolate.
