title: Two-year study evaluating the potential loss of methicillin resistance in a methicillin-resistant Staphylococcus aureus culture collection.
abstract: A reported loss of mecA prompted us to monitor 360 cryostocked methicillin-resistant Staphylococcus aureus strains for stability. Concurrently, 14 well-characterized strains were stored in a Microbank preservation system and subjected to multiple freeze-thaw events. There were no significant declines in the methicillin-resistant populations with either method over a two-year period.
