Consider listeriosis in cases of neonatal sepsis or meningitis and in cases of sepsis or meningitis in children who are immunocompromised.

  • Listeria is acquired by ingestion of contaminated food products.

  • Mothers who acquire Listeria may experience influenzalike illnesses, with headache, malaise, fever, backache, nausea, vomiting, diarrhea, and chills. Mothers with Listeria infections may also undergo premature labor. [11]

  • Listeria in newborns can be classified as early onset or late-onset infection.

  • Meconium-stained amniotic fluid is common in newborns with early onset Listeria.

  • Respiratory difficulty is common, including a history of cyanotic episodes, rapid breathing, and grunting.

  • Parents and health care providers may report poor feeding and fever.
