Listeria Meningitis

Listeriosis meningitis is an infection of the lining of the brain and spinal cord. If your loved one has been diagnosed with this severe illness, it means he or she ate food contaminated with deadly bacteria called Listeria monocytogenes. Listeria is a genus of bacteria. Until 1992, 10 species were known, each containing two subspecies. By 2019, 20 species had been identified.The genus received its current name, after the British pioneer of sterile surgery Joseph Lister, in 1940. Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce endospores. The major human pathogen in the genus Listeria is L. monocytogenes. It is usually the causative agent of the relatively rare bacterial disease listeriosis, an infection caused by eating food contaminated with the bacteria. Listeriosis can cause serious illness in pregnant women, newborns, adults with weakened immune systems and the elderly, and may cause gastroenteritis in others who have been severely infected.   Listeriosis is a serious disease for humans; the overt form of the disease has a case-fatality rate of around 20%. The two main clinical manifestations are sepsis and meningitis. Meningitis is often complicated by encephalitis, when it is known as meningoencephalitis, a pathology that is unusual for bacterial infections.
