PNAS: Subdiffusive motion of bacteriophage in mucosal surfaces increases the frequency of bacterial encountersBy Jeremy Barr et al.
Bacteriophages (phages) are viruses that infect and kill bacteria. Being inanimate, phages rely on diffusion to search for bacterial prey. Here we demonstrate that a phage that adheres weakly to mucus exhibits subdiffusive motion, not normal diffusion, in mucosal surfaces. Supporting theory and experiments revealed that subdiffusive motion increases bacterial encounter rates for phages when bacterial concentration is low. To the best of our knowledge, no other predator has been shown to effectively use a subdiffusive search mechanism. Mucosal surfaces are vulnerable to infection. Mucus-adherent phages reduce bacterial infection of lifelike mucosal surfaces more effectively than nonadherent phages. These findings provide a basis for engineering adherent phages to manipulate mucosal surface microbiomes for protection from infection and other purposes.
