Listeriosis During Pregnancy and in Newborns: 18 Years of Data From a Large Tertiary Hospital in Singapore.

A 20-year retrospective review at a tertiary hospital in Singapore identified 11 cases of perinatal listeriosis in maternal-fetal pairs (incidence, 4.8 cases per 100 000 live births). Fever, meconium-stained amniotic fluid, and fetal akinesia during the third trimester were associated with listeriosis.
