This discovery and the characterization of Naegleriaviruses were made possible through international collaboration with researchers from the universities in Poitiers, the Canary Islands, and the US-based Joint Genome Institute.
Viruses are employed in phage therapy to combat bacterial pathogens. “The newly identified Naegleriaviruses may not be suitable to treatinfections, given the challenging accessibility of the brain, where infections occur. However, this discovery opens the door to the possibility of preventative treatment of at-risk water bodies, such as during swimming pool water treatment, but this would first require further research.
