Patterns of Ciprofloxacin-Resistant Gram-Negative Bacteria Colonization in Nursing Home Residents

We evaluated the prevalence of colonization with all gram-negative bacilli (GNB) and with ciprofloxacin-resistant GNB among nursing home residents with and without indwelling devices. We found that device presence increases the risk of colonization with all GNB and with ciprofloxacin-resistant GNB. Colonization with ciprofloxacin-resistant GNB increases with decreasing functional status.
