Listeriosis
Listeriosis is a bacterial infection caused by a gram-positive, motile bacterium, Listeria monocytogenes. It occurs primarily in newborn infants, elderly and immunocompromised patients. Listeriosis is a relatively rare infection but has become significant with upsurge in HIV - AIDS. Ingestion of contaminated food products viz raw meat, dairy products, vegetables, seafood, soft cheeses and unpasteurized milk are the main route of acquisition of Listeria. Sepsis or meningitis is the most common clinical presentation. Ampicillin is the drug of choice with an aminoglycoside added for synergistic effect.
