Salmonella poona infection and surveillance in a neonatal nursery.

BACKGROUND

This article reports the first known outbreak of Salmonella poona infection in a neonatal unit. Three babies had stool cultures positive for the organism. At the same time, S. poona was the cause of a nationwide food-borne outbreak associated with contaminated canteloupe. To minimize the neonatal outbreak, surveys were performed and control measures were instituted.

METHODS

Epidemiologic surveillance included the culture of rectal swabs collected from 48 employees, 18 babies, and four family members of the babies. Control measures used included the placement in cohorts and isolation of infected babies, strict adherence to universal precautions, and the restriction of visitation in the nursery.

RESULTS

A total of three babies and one employee in the surveillance were found to have Salmonella sp. An additional two hospitalized adult patients had S. poona. Of all the people included in the surveillance, only the three babies were found to have S. poona. The hospital employee had S. enteritidis.

CONCLUSIONS

Timely culture results, rapid cohort placement of infected babies, and strict adherence to universal precautions led to the successful eradication of the organism.
