Comments:
Useful for diagnosis of Acanthamoeba species and Naegleria fowleri in the central nervous system (CNS) or eye. The free-living amoebae are ubiquitous in the environment, and may be found in soil and fresh water sources. Naegleria fowleri may enter the central nervous system during exposure to infected water and cause a fulminant meningitis in previously healthy individuals. In contrast, Acanthamoeba species and Balamuthis mandrillaris cause chronic granulomatous encephalitis in immunocompromised (and rarely, immunocompetent) adults, and typically disseminate to the CNS from a primary lung or skin source.
