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 Listeria monocytogenes. 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.
