Listeria monocytogenes is a bacterial pathogen and causative agent for the foodborne infection listeriosis, which is mainly a threat for pregnant, elderly, or immunocompromised individuals. Due to its ability to invade and colonize diverse eukaryotic cell types including cells from invertebrates, L. monocytogenes has become a well-established model organism for intracellular growth.

Despite difficulties associated with the collection of adequate data from outbreak investigations or sporadic cases, the limitations of currently available animal models, and the inability to conduct human volunteer studies, some of the available data now allow refinements of the well-established exponential L.

Introduction: Empiric parenteral ampicillin has traditionally been used to treat listeria and enterococcal serious bacterial infections (SBI) in neonates 28 days of age or younger. Anecdotal experience suggests that these infections are rare. Existing data suggest an increasing resistance to ampicillin.

Listeria monocytogenes (Lm) is the etiological agent of listeriosis, one of the deadliest human foodborne infections. Lm is able to cross the intestinal, placental and blood-brain barriers, leading to septicemia, fetoplacental infection, meningitis and encephalitis. The intracellular life cycle of this facultative intracellular bacterium has been studied in detail in in vitro cell culture systems.

Listeriolysin O (LLO) is a toxin produced by Listeria monocytogenes, an opportunistic bacterial pathogen responsible for the disease listeriosis. This disease starts with the ingestion of contaminated foods and mainly affects immunocompromised individuals, newborns, and pregnant women. In the laboratory, L.
