What Are the Basics of Listeria Monocytogenes?

What is listeria monocytogenes?

Listeriosis is a disease caused by the proliferation of listeria monocytogenes, usually after eating contaminated food or liquid.

 

What are the symptoms of listeria monocytogenes?

The symptoms and signs of listeriosis can vary widely, and clinical presentation often depends largely on the patient’s health and age. Most healthy individuals infected with mononuclear listeria have no symptoms, although they rarely develop mild self-limiting gastrointestinal diseases. There can be a significant delay from a few days to two or three months. The symptoms of listeriosis include:

  • fever
  • muscle aches
  • diarrhea.

 

What is the treatment for listeriosis?

Starting antibiotics immediately when suspected or diagnosed can speed recovery and prevent the more serious potential complications that listeriosis sometimes encounters.

Intravenous medications can be used to treat nausea and/or vomiting.

Most authorities believe that even those who eat food contaminated with listeria do not need treatment if there are no signs or symptoms of infection.

Pregnant women must be taken seriously, however, because listeriosis can potentially damage fetuses and newborns.
