Listeriosis Infection In Pregnancy: A Case Series

Listeriosis is a rare foodborne febrile illness that has a unique predilection for the pregnant population. Listeriosis during pregnancy can cross the placenta, resulting in vertical transmission to the fetus which frequently results in adverse pregnancy outcomes. This is a case series on three pregnant patients who were treated for listeriosis at Latifa Women and Children's Hospital. All three patients reported in this series had no medical comorbidities or pregnancy risk factors; they presented with fever and abdominal and/or back pain; and of significance, none of the patients reported a history of gastrointestinal tract symptoms. Two cases were in the second trimester and one in the third trimester. All cases resulted in fetal loss with 100% fetal mortality. There was no maternal mortality or long-term morbidity in any of the patients.
