Natural History of Colonization With Vancomycin-Resistant Enterococci, Methicillin-Resistant Staphylococcus Aureus, And Resistant Gram-Negative Bacilli Among Long-Term–Care Facility Residents

Among LTCF residents, colonization with resistant gram-negative bacilli is four times more likely to clear than colonization with VRE or MRSA. Performance of surveillance cultures at regular intervals may reduce the need for contact precautions for LTCF residents with resistant gram-negative bacilli colonization.
