Forskare uppmanar till närmare övervakning av fritt levande amöbor – mikroskopiska organismer som finns i jord och vatten – och varnar för att vissa arter kan orsaka allvarliga, ibland dödliga infektioner och är svåra att kontrollera i vattensystem.
Fritt levande amöbor – encelliga organismer som naturligt förekommer i jord och vatten – väcker ny uppmärksamhet som ett potentiellt hot mot folkhälsan, enligt en perspektivartikel publicerad i tidskriften Biocontaminant.
De initiala reaktionerna på X till artikeln är få och består främst av delningar som länkar till ScienceDaily-släppet. Inläggare framhåller de fritt levande amöborna motståndskraft mot värme och klor, deras förmåga att hysa patogener och exempel som hjärnätande amöbor. Stämningarna är mestadels neutrala, med vissa larmtoner som kopplar hotet till klimatförändringar och åldrande infrastruktur, och kräver brådskande övervakning och vattensäkerhet.

SCIENCE WARNING: "BRAIN-EATING" AMOEBAS SPREADING 🦠🌡️
This isn't a movie script. It’s a new global health alert.
Scientists warn that dangerous "free-living amoebas" (like Naegleria fowleri) are spreading globally due to climate change.

Scientists are monitoring Vibrio bacteria, including the dangerous strain vulnificus, as it expands northward along the US East Coast amid rising ocean temperatures. Researchers at the University of Florida are developing an early warning system to predict high-risk areas a month in advance. The bacteria thrives in warm, brackish waters and poses greater risks to those with weakened immune systems.

Researchers at the University of Waterloo have developed engineered bacteria designed to invade and eat solid tumors from the inside out. The approach uses microbes that thrive in oxygen-free environments, targeting the low-oxygen cores of tumors. A genetic modification allows the bacteria to survive near oxygenated edges, controlled by a quorum-sensing mechanism.
Researchers have demonstrated that the single-celled protist Stentor coeruleus can engage in associative learning, similar to Pavlov's experiments with dogs. This finding suggests such cognitive abilities may predate the evolution of brains by hundreds of millions of years. The study highlights unexpected complexity in simple organisms.

Researchers at the University of York have identified a protein called ESB2 that acts as a molecular shredder, enabling the African trypanosome parasite to evade the human immune system. The parasite, which causes sleeping sickness, uses ESB2 to precisely edit its genetic instructions in real time. This breakthrough solves a 40-year mystery in the parasite's biology.
