Fever in Pregnancy: A Rare Case of Listeria-Induced Chorioamnionitis

Listeriosis is a rare infection during pregnancy and may result in complications such as chorioamnionitis. Diagnosis is hardly made due to the nonspecific symptoms of listeriosis. A 27-year-old pregnant woman at 27 weeks and 3 days of gestation was admitted with a history of fever for 6 days and decreased fetal movement. Administration of broad-spectrum antibiotics initially did not improve her condition. Amniocentesis was suggestive of chorioamnionitis, and culture was positive for <i>Listeria monocytogenes</i>. In view of that, delivery was indicated for the safety of the mother and baby. Her case highlights the necessity of maintaining a high index of suspicion for listeriosis in pregnant patients with a history of exposure who present with fever without an evident underlying cause. Early diagnosis and management are very important for a better prognosis in such an illness. Educating pregnant women about dietary precautions and prompt medical care may prevent severe complications.
