Cerebrospinal fluid centrifuge analysis in primary amebic meningoencephalitis due to Naegleria fowleri

Insights

This report details the first known case of primary amebic meningoencephalitis caused by Naegleria fowleri in Missouri. Morphologic identification of amebas in cerebrospinal fluid is emphasized for diagnosis.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Primary amebic meningoencephalitis (PAM) is a rare and fatal infection of the central nervous system.
  • Naegleria fowleri is a free-living ameba responsible for PAM, typically found in warm freshwater environments.

Observation:

  • This case represents the first documented occurrence of Naegleria fowleri infection in Missouri.
  • The patient presented with symptoms consistent with rapidly progressive meningoencephalitis.

Findings:

  • Morphologic identification of degenerating amebas was successfully performed on a cerebrospinal fluid cytospin preparation.
  • Wright's stain proved effective in visualizing the amebic forms during the acute stage of the illness.

Implications:

  • This case highlights the geographic expansion or increased recognition of Naegleria fowleri in new regions.
  • Early diagnostic methods, including microscopic examination of CSF, are crucial for timely identification and management of PAM.
  • Increased awareness among clinicians in Missouri regarding this rare but devastating infection is warranted.

Bacterial 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...
Viral Meningitis01:18

Viral 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...

Cryptococcal 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,...

Bacterial 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...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Encephalitis 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...
