Abstract
Patient colonization with extended-spectrum β-lactamase–producing gram-negative bacteria (ESBL-GNB) could serve as a
potential reservoir for transmission of multidrug-resistant (MDR)
bacteria in a hospital setting. Individuals colonized with ESBLEnterobacteriaceae are also known to be at a higher risk of ESBLGNB infection following their colonization.1 We encountered an
outbreak of MDR Klebsiella pneumoniae in the neonatal care unit
(NCU) of the Médecins Sans Frontiéres (MSF) obstetric emergency hospital in Port au Prince (CRUO), Haiti, between 2014
and 2015.2 As part of ongoing surveillance activities for MDR
bacteria and in an effort to better target infection, prevention,
and control (IPC) measures throughout the hospital, we conducted a point-prevalence survey to estimate the prevalence of
colonization with ESBL-GNB and to identify risk factors for
colonization with ESBL-GNB in women and neonates admitted
to this hospital.
