Listeriosis in pregnancy: a common yet underdiagnosed cause of febrile illness.

Abstract Food borne listeria infection is common in pregnancy as compared to general population because of the reduced immune defense mechanism in pregnancy. It may cause maternal morbidity and fetal mortality if not treated on time. Precooked meat and milk products are the main source of listeria.  The diagnosis is confirmed by blood culture and the infection is cured with ampicillin. This case report is of a patient presenting with febrile illness in second trimester of pregnancy. She gets promptly investigated for possible differential diagnosis, bacterial, viral and protozoal. Maternal complication increased till definitive management is offered.
