Prolonged colonization with the methicillin-resistant Staphylococcus aureus strain USA300 among residents of extended care facilities.
We performed a retrospective cohort study (n=129) to assess whether residents of extended care facilities who were initially colonized or infected with the methicillin-resistant Staphylococcus aureus (MRSA) strain USA300 were less likely to have prolonged colonization than were residents colonized or infected with other MRSA strains. We found no difference in prolonged colonization (adjusted odds ratio, 1.1 [95% confidence interval, 0.5-2.4]).
