Survival of methicillin-resistant Staphylococcus aureus (MRSA) on naturally contaminated dry mops.

Author information

Department of Pharmacy, Yamaguchi University Hospital, Ube, Japan.


The floors of single rooms being used by inpatients colonized by methicillin-resistant Staphylococcus aureus (MRSA) were cleaned using disposable dust-attracting dry mops. Each mop was divided into 12 sections and MRSA quantified serially. This experiment was repeated a total of 21 times for four patients. The MRSA survival rate on the dry mops compared with a control was 59.0-125% after seven days, 26.3-41.6% after 14 days, 0.1-16.2% after 28 days, 0-0.1% after 56 days and 0% after 84 days. MRSA disseminated by patients over the environment can survive for several weeks on dry mops.
