Listeria meningitis in an immunocompetent child
Helvetica Paediatrica Acta
|June 1, 1982
Summary
A healthy 3-year-old boy developed Listeria monocytogenes meningitis, a rare occurrence in this age group. This case highlights potential environmental factors in pediatric meningitis, even without identified immune deficiencies.
Area of Science:
- Pediatric Infectious Diseases
- Neurology
- Immunology
Background:
- Listeria monocytogenes is a bacterium that can cause serious infections, including meningitis.
- Meningitis is an inflammation of the membranes surrounding the brain and spinal cord.
- While often opportunistic, Listeria meningitis can occur in individuals without apparent immune defects.
Observation:
- A 3-year-old boy, with no detectable immunologic defect, presented with Listeria monocytogenes meningitis.
- The patient resides in an area with a known high incidence of Listeria in local livestock.
- This demographic and geographic profile is unusual for Listeria meningitis.
Findings:
- This represents the first reported case in English literature of Listeria meningitis in a child with a normal immune status.
- The case challenges the typical understanding of Listeria as solely an opportunistic pathogen in immunocompromised individuals.
- The patient's age group is generally considered less susceptible to opportunistic infections.
Implications:
- Environmental exposure, particularly to livestock, may play a significant role in pediatric Listeria meningitis.
- Further investigation into non-immunocompromised risk factors for Listeria meningitis is warranted.
- This case underscores the importance of considering environmental epidemiology in pediatric infectious disease diagnosis.

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
