Overview
The clinical manifestation of listeriosis is host-dependent. Immunocompetent persons may experience acute febrile gastroenteritis or no symptoms. Among older adults and immunocompromised persons, the most common clinical presentations are septicemia and meningitis. Pregnant women may experience a mild flu-like illness, followed by fetal loss, or bacteremia and meningitis in the newborns.
History
Although the source is often unknown, contaminated food is the most common vehicle of transmission. Listeria has an incubation period that can range from a median of 24 hours, in Listeria gastroenteritis, to a median of 35 days, in Listeria invasive disease.[1][2][3] Patients who present with symptoms suggestive of listeriosis should be inquired about history of ingested of uncooked meats and vegetables, unpasteurized (raw) milk and cheeses, processed (or ready-to-eat) meats, and smoked seafood within the last few weeks.
Symptoms
Although some patients may be transitory asymptomatic carriers of listeriosis, others become symptomatic. There is a variety of clinical presentations depending on the affected systems and the immune status of the host.
Febrile Gastroenteritis
Infection in Pregnancy
Sepsis of Unknown Origin
Bacteremia
CNS Infection
Meningoencephalitis
The clinical presentation can range from mild fever and mental status changes, to a more aggressive course with coma. Focal neurological signs might be present, such as:
- Cranial nerve abnormalities
- Ataxia
- Tremors
- Hemiplegia
- Deafness
- Seizures
Cerebritis/ Encephalitis
In cerebritis/encephalitis, the clinical picture is dominated by altered consciousness and cognitive dysfunction. Additional symptoms include:[4]
Rhombencephalitis
Rhombencephalitis often follows a biphasic course. The initial phase lasts for about 4 days and is characterized by the following symptoms:
The initial phase is followed by an abrupt onset of:
- Asymetrical cranial nerve palsies
- Ataxia
- Tremor
- Decreased consciousness
- Seizures
- Hemiparesis and/or hemisensory deficits
- Respiratory failure
