Listeria is a food-borne pathogen responsible for a disease called listeriosis, which is potentially lethal in immunocompromised individuals. It is a genus of bacteria that acts as an intracellular parasite in mammals and as of 2020 was known to contain 21 species. 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 (Radoshevich & Cossart, 2018).
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.
L. ivanovii is a pathogen of mammals, specifically ruminants, and has rarely caused listeriosis in humans.
