  abstract = {{T}he grazing activity by specific marine organisms represents a growing threat to the survival of many scleractinian species. {F}or example, the recent proliferation of the corallivorous gastropod {D}rupella now constitutes a critical case in all {S}outh-{E}ast {A}sian waters. {I}f the damaging effects caused by this marine snail on coral polyps are relatively well known, the indirect incidence of predation on coral microbial associates is still obscure and might also potentially impair coral health. {I}n this study, we compared the main ecological traits of coral-associated bacterial and viral communities living in the mucus layer of {A}cropora formosa and {A}cropora millepora, of healthy and predated individuals (i.e., colonized by {D}rupella rugosa), in the {B}ay of {V}an {P}hong ({V}ietnam). {O}ur results show a substantial impact of the gastropod on a variety of microbiological markers. {C}olonized corals harbored much more abundant and active epibiotic bacteria whose community composition shifted toward more pathogenic taxa (belonging to the {V}ibrionales, {C}lostridiales, {C}ampylobacterales, and {A}lteromonadales orders), together with their specific phages. {V}iral epibionts were also greatly influenced by {D}rupella corallivory with spectacular modifications in their concentrations, life strategies, genotype richness, and diversity. {N}ovel and abundant circular {R}ep-encoding ss{DNA} viruses ({CRESS}-{DNA} viruses) were detected and characterized in grazed corals and we propose that their occurrence may serve as indicator of the coral health status. {F}inally, our results reveal that corallivory can cause severe dysbiosis by altering virus-bacteria interactions in the mucus layer, and ultimately favoring the development of local opportunistic infections.},
