Abstract	Listeria monocytogenes (L. monocytogenes) is a gram-positive, facultative, intracellular bacterium that causes meningitis, meningoencephalitis, and infrequently hydrocephalus and cerebral bleeding. These infections are more prone to occur in elderly, pregnant women, new-borns and immunocompromised patients than healthy adults. It is transmitted either vertical transmission from mother to child or through ingestion of contaminated food. Patients may present with symptoms like fever, headache and signs of meningitis. The patient may have an altered mental status with a drop in GCS. It is diagnosed through CSF analysis, blood cultures, placental fluid cultures and now through molecular testing and contributed by MRI imaging. Since listeria meningoencephalitis has a high mortality rate of up to 30%, if it is not identified and treated quickly, it can cause coma, irreversible brain damage, and even death.
