The US military has seen steady increases in multidrug-resistant MDR gram-negative bacteria GNB infections in casualties from Iraq and Afghanistan. This study evaluates the prevalence of MDR GNB colonization in US military personnel. GNB colonization surveillance of healthy, asymptomatic military personnel 101 in the US and 100 in Afghanistan was performed by swabbing 7 anatomical sites, US-based personnel had received no antibiotics within 30 days of specimen collection, and Afghanistan-based personnel were receiving doxycycline for malaria chemoprophylaxis at time of specimen collection. Isolates underwent genotypic and phenotypic characterization.
