Jellyfish blooms-an overlooked hotspot and potential vector for the transmission of antimicrobial resistance in marine environments.

ABSTRACT: Gelatinous zooplankton (GZ) represents an important component of marine food webs, capable of generating massive blooms with severe environmental impact. When these blooms collapse, considerable amounts of organic matter (GZ-OM) either sink to the seafloor or can be introduced into the ocean's interior, promoting bacterial growth and providing a colonizable surface for microbial interactions. We hypothesized that GZ-OM is an overlooked marine hotspot for transmitting antimicrobial resistance genes (ARGs). To test this, we first re-analyzed metagenomes from two previous studies that experimentally evolved marine microbial communities in the presence and absence of OM from Aurelia aurita and Mnemiopsis leidyi recovered from bloom events and thereafter performed additional time-
