Listeriosis in newborns

[Oralee]

Listeriosis is infection caused by the bacteria Listeria monocytogenes.

Listeriosis in newborns can be acquired in the womb or during or after delivery.
Symptoms vary but may include listlessness and poor feeding.
The diagnosis is confirmed by identifying the bacteria in a sample of blood or other material taken from the newborn and mother.
Some newborns die from the infection.
Pregnant women should avoid certain foods and properly wash their hands and kitchen equipment after handling uncooked foods.
Antibiotics can cure the infection.

The Listeria monocytogenes bacteria resides in the intestine of some people and many animals worldwide. Unlike many other organisms, it survives well at refrigerator temperatures.
Pregnant women can become infected if they eat contaminated food. These foods include unpasteurized dairy products, soft cheeses, raw vegetables, prepared deli meats and salads, refrigerated meat spreads, or smoked seafood. Fetuses become infected if Listeria monocytogenes crosses the placenta (the organ that provides nourishment to the fetus) during pregnancy. Newborns may become infected during or after delivery.
