Abstract:
We report the first case of primary amebic meningoencephalitis in Italy, in a 9-year-old boy. Clinical course was fulminant, and diagnosis was made by identifying amebas in stained brain sections and by indirect immunofluorescence analysis. Naegleria fowleri was characterized as genotype I on the basis of polymerase chain reaction test results.
Insights
The first case of primary amebic meningoencephalitis in Italy was a 9-year-old boy. Diagnosis involved identifying Naegleria fowleri amebas in brain tissue, confirmed by PCR as genotype I.
Area of Science:
- Neurology
- Infectious Diseases
- Parasitology
Background:
- Primary amebic meningoencephalitis (PAM) is a rare and fatal brain infection.
- Naegleria fowleri is the causative agent, typically found in warm freshwater.
Observation:
- A 9-year-old boy in Italy presented with a fulminant clinical course consistent with PAM.
- Amebas were identified in stained brain sections.
Findings:
- Indirect immunofluorescence analysis confirmed the presence of amebas.
- Polymerase chain reaction (PCR) identified the pathogen as Naegleria fowleri, genotype I.
Implications:
- This case represents the first documented occurrence of PAM in Italy.
- Highlights the importance of diagnostic methods for Naegleria fowleri infections.
- Contributes to understanding the geographical distribution of Naegleria fowleri genotypes.
