Listeria monocytogenes is a bacterial pathogen that can invade the central nervous system (CNS), causing meningoencephalitis and brain abscesses. The diagnosis of CNS listeriosis, based on the isolation of the bacteria in the cerebrospinal fluid (CSF), can be difficult because of previous antibiotic treatment and a low number of bacteria in the CSF.1. Introduction. Listeria monocytogenes and L. innocua are closely related species of the Gram-positive genus Listeria.They are widely distributed in the environment and frequently isolated from food. L. monocytogenes is the causative agent of listeriosis, a foodborne disease with a high fatality rate (20-30%) that mostly affects the elderly, neonates, and immunocompromised individuals [1, 2].Listeria monocytogenes is a food-borne pathogen responsible for a disease called listeriosis, which is potentially lethal in immunocompromised individuals.

Listeria monocytogenes is a Gram-positive facultative anaerobic bacterium that is responsible for the disease, listeriosis. It is particularly lethal in pregnant women, the fetus, the elderly and the immunocompromised. The pathogen survives and replicates over a wide range of temperatures (4 to 42 °C), pH, salt and oxygen concentrations.Listeria monocytogenes is acquired by ingestion of contaminated food and attaches to the intestinal mucosa. In mouse and guinea pig models, M cells or Peyer's patches may be the primary intestinal invasion site. It is thought that α-d-galactose residues on the bacterial surface bind the α-d-galactose receptors on intestinal cells.Flagella may be an important …Listeria monocytogenes is a facultative, intracellular, gram-positive rod that is responsible for causing the infection listeriosis.
