Listeriosis is an infection caused by Listeria monocytogenes bacteria. It can be a serious disease. The most common source of infection is contaminated food such as deli meats, unpasteurized milk or dairy products, soft cheeses, and paté. Despite being so widespread, most infections in humans result from eating contaminated foods. Listeriosis has recently been recognized as an important public health problem in the United States.

Infection is rare, but when it does occur it most frequently affects pregnant women in their last trimester, newborns, and children and adults whose immunity is weakened by diseases such as cancer or AIDS.In the United States, an estimated 1,850 persons become seriously ill with listeriosis each year. While many bacteria generally infect specific locations within the human body, Listeria may infect many different sites, such as the brain or spinal cord membranes or the bloodstream.

Listeria monocytogenes is a Gram-positive rod-shaped bacterium.Most people are not at increased risk for listeriosis. However, there are some people who are considered at risk because they are more susceptible to listeriosis. Animals and people can carry Listeria in their bodies without becoming sick. The disease affects primarily pregnant women, newborns, and adults with weakened immune systems.

Once infected, Listeria lives in the gastrointestinal tract.. In direct smears they may be coccoid, so they can be mistaken for streptococci. Longer cells may resemble corynebacteria. The true incidence of listeriosis in humans is not known, because in the average healthy adult, infections are usually asymptomatic, or at most produce a mild influenza-like disease. Most people are not at increased risk for listeriosis. However, there are some people who are considered “at risk” because they are more susceptible to listeriosis.
