[Perinatal listeriosis--a case report].

Listeria monocytogenes, an uncommon perinatal infection in human, has been reported to be correlated with abortion, premature labor, intrauterine fetal sepsis, intrauterine fetal death and neonatal infections. Reported here was the first case of perinatal listeriosis complicated with Listeria monocytogenes chorioamnionitis at 33 weeks' gestation in Taiwan. The transabdominal amniocentesis in this particular case confirmed the diagnosis. An live premature male fetus was delivered by emergency cesarean section on the next day of hospitalization due to acute fetal distress. The acute ill baby developed signs of meningitis on the following day. Blood culture of Listeriosis monocytogenes indicated early onset neonatal listeriosis. Brain sonography showed hydrocephalus after a one-month period antibiotic treatment, he was lost to follow-up one month later. A review of the literature is presented to describe the clinical, epidemiological and pathological findings and to highlight their variable presentations and procedures for management. Thus it is of great importance for obstetricians to include listeriosis as a differential diagnosis in cases of fever of unknown origin during pregnancy. Promptly obtaining proper cultures and instituting appropriate antibiotics therapy is emphasized.
