Rapid bedside test for the brain‑eating amoeba Naegleria fowleri

Development of a latex-agglutination assay for the rapid detection of Naegleria fowleri

What this research studies

Researchers will make antibodies by inoculating rabbits and purifying the antibodies that stick to Naegleria fowleri. Those antibodies will be attached to dyed latex beads to create a read‑out that clumps when the amoeba is present, giving results in under 15 minutes without extra equipment. The team will compare the new clumping test to current methods like microscopy and nucleic acid tests using prepared samples and cerebrospinal fluid from infected animals. They will also check for cross‑reaction with common bacterial and fungal causes of meningitis to make sure the test is specific.

Who could benefit from this research

Good fit: People who present with sudden meningitis‑like symptoms after freshwater exposure and who undergo a lumbar puncture would be the likely candidates for using this test.

Not a fit: People without suspected central nervous system infection or those who cannot have a spinal tap would not benefit from this test.

Why it matters

Potential benefit: If successful, this test could let clinicians diagnose deadly Naegleria fowleri infections at the bedside much faster, potentially enabling earlier treatment.

How similar studies have performed: Rapid latex‑agglutination and point‑of‑care tests work for other pathogens, but applying this approach to Naegleria fowleri is largely novel and is being tested here.
