An outbreak of Campylobacter jejuni infection in a neonatal intensive care unit.

During a period of 2 weeks Campylobacter jejuni infection was diagnosed in seven infants in a neonatal intensive care unit. An identical serotype of Camp. jejuni was found in five of the cases. Investigations suggested that a common source of infection or infection acquired from mothers during delivery were unlikely. The dates of onset and the common serotype indicate that the outbreak may have been caused by person-to-person spread.
