Extended spectrum ß-lactamase-producing Escherichia coli in neonatal care unit

Emerg Infect Dis. 2010 Nov;16(11):1758-60. doi: 10.3201/eid1611.100366.


An outbreak of extended-spectrum ß-lactamase-producing Escherichia coli in a neonatal care unit began with transmission from a mother to her newborn twins during vaginal delivery. Subsequently, infection spread by healthcare worker contact with other neonates; a healthcare worker also was infected. Knowledge about transmission may improve infection control measures.
