[Listeria monocytogenes in human infections].

The Listeria genus is distinguished into six species from which just one--Listeria monocytogenes is pathogenic for humans. The main route of acquisition of Listeria is through the ingestion of contaminated food products. An important element of the L. monocytogenes pathogenesis infection is affiliation with high-risk group of immunocompromised patients, infants or pregnant women, who infected by this microorganism can lead to miscarriage. Listeriosis can appear in the form of sepsis, infection of the nervous system or local abscesses. Another form of listeriosis is gastrointestinal tract infection--noticed in case of food poisoning outbreak.
