Four Novel <i>Caudoviricetes</i> Bacteriophages Isolated from Baltic Sea Water Infect Colonizers of <i>Aurelia aurita</i>.

ABSTRACT: The moon jellyfish Aurelia aurita is associated with a highly diverse microbiota changing with provenance, tissue, and life stage. While the crucial relevance of bacteria to host fitness is well known, bacteriophages have often been neglected. Here, we aimed to isolate virulent phages targeting bacteria that are part of the A. aurita-associated microbiota. Four phages (Staphylococcus phage BSwM KMM1, Citrobacter phages BSwM KMM2-BSwM KMM4) were isolated from the Baltic Sea water column and characterized. Phages KMM2/3/4 infected representatives of Citrobacter, Shigella, and Escherichia (Enterobacteriaceae), whereas KMM1 infected Gram-positive Staphylococcus spp. All phages showed an up to 99% adsorption to host cells within 5 m
