- Pathogen: Acanthamoeba spp.—a free-living amoeba that causes Granulomatous Amoebic Encephalitis (GAE), a rare but typically fatal brain infection.
- Unlike Naegleria fowleri (which causes rapid PAM), Acanthamoeba GAE usually affects immunocompromised individuals and progresses over weeks to months.
- Location: State Public Health Laboratory (SPHL), Thiruvananthapuram, Kerala.
- Scientific Advancement: SPHL developed and used in-house molecular diagnostic kits (PCR-based) for Free-Living Amoeba (FLA) species.
- Milestone: This is the first time the presence of Acanthamoeba spp. has been confirmed in a human cerebrospinal fluid (CSF) sample within Kerala using local molecular methods.
- Impact on Public Health:
- Eliminates Reliance: Kerala no longer has to depend on external national labs (like PGI Chandigarh) for confirmatory molecular testing.
- Early, Targeted Treatment: Accurate, rapid diagnosis is crucial for the highly fatal condition. Early identification of the specific amoeba allows doctors to optimize the drug regimen (e.g., using Miltefosine and Azole antifungals) and avoid presumptive, often ineffective, therapy.
- Surveillance: The new kits can identify up to five pathogenic amoeba species (including Naegleria fowleri, Balamuthia mandrillaris, and Acanthamoeba spp.), enabling faster response to cases of Acute Encephalitis Syndrome (AES) and potential environmental testing.
This breakthrough is considered a “game-changer” for the state’s public health system in combating rare and deadly amoebic infections.
