Bacteriophages and bacterial biofilms are widely present in natural environments, a fact that
has accelerated the evolution of phages and their bacterial hosts in these particular niches.
Phage-host interactions in biofilm communities are rather complex, where phages are not
always merely predators but also can establish symbiotic relationships that induce and
strengthen biofilms. In this review we provide an overview of the main features affecting
phage-biofilm interactions as well as the currently available methods of studying these …
