A recent perspective article by environmental and public health scientists highlights free-living amoebae as an emerging global health concern. These microscopic, single-celled organisms naturally inhabit soil, freshwater, and man-made water systems. While most are harmless, certain species, such as Naegleria fowleri, can cause deadly infections. These amoebae are difficult to control because they survive extreme conditions, including high temperatures, chlorine disinfection, and aging water infrastructure. Researchers warn that amoebae can harbor other harmful microbes, acting as protective hosts in a 'Trojan horse' effect that allows bacteria and viruses to survive and potentially spread, raising concerns about antibiotic resistance. Climate change exacerbates the problem by expanding warm environments where these organisms thrive, leading to outbreaks in regions previously unaffected. Scientists advocate for a coordinated One Health approach, integrating human health, environmental
