Genomic DNA from methicillin-resistantStaphylococcus aureus isolates recovered from pigs and their caretakers proved resistant to SmaI digestion, leading to uninterpretable results in standard pulsed-field gel electrophoresis. This is the result of a yet unknown restriction/methylation system in the genusStaphylococcus with the recognition sequence CCNGG.
