A new study highlights the increasing global threat posed by brain-eating amoebae, such as Naegleria fowleri, which can cause fatal brain infections. Researchers attribute this rise to climate change, aging water infrastructure, and inadequate monitoring. These amoebae are resilient, surviving high temperatures and disinfectants, and can act as carriers for other pathogens, potentially spreading antibiotic resistance. Climate warming is expected to expand their range into new regions.
