Overview
Listeriosis can present in different ways depending on the type of infection, such as: fever, headacheand muscle aches, sometimes preceded by diarrhea or other gastrointestinal symptoms. Other less common symptoms may include: stiff neck, confusion and convulsions. It has an incubation period which can range from a median of 24 hours, in Listeria gastroenteritis, to a median of 35 days, in Listeria invasive disease. Manifestations of listeriosis are host-dependent. 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 their newborns. Immunocompetent persons may experience acute febrile gastroenteritis or no symptoms.
History
Symptoms
Although some patients may be transitory carriers of listeriosis, others become symptomatic. Depending on the affected systems, symptoms might include:
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. There may also be an encephalic component present, which will present with focal neurological signs, such as:
- Cranial nerve abnormalities
- Ataxia
- Tremors
- Hemiplegia
- Deafness
- Seizures
Cerebritis/ Encephalitis
In these cases, the clinical picture is dominated by altered consciousness and cognitive disfunction, but may also manifest as:[1]
Rhombencephalitis
Rhombencephalitis often follows a biphasic course, beginning with:
Which lasts for about 4 days, and is followed by an abrupt onset of:
- Asymetrical cranial nerve palsies
- Ataxia
- Tremor
- Decreased consciousness
- Seizures
- Hemiparesis and/or hemisensory deficits
- Respiratory failure
Endocarditis
Listerial endocarditis affects the population at risk for streptococcus viridans endocarditis, producing native and prosthetic valve disease and having an elevated rate of septic complications. Listerial endocarditis alone, may be an indicator of a GI tract abnormality, such as cancer[2].
