  abstract = {{I}n marine environments, plastic debris serves as a vector for pathogenic bacteria that can negatively impact marine fauna, including corals. {T}he {S}aya de {M}alha and {N}azareth {B}anks, located in the {I}ndian {O}cean, harbor an extensive area of coral reefs that may be susceptible to diseases associated with plastic pollution. {I}n this context, we aimed to determine whether plastic debris in this region can act as a vector for coral-associated pathogenic bacteria. {D}uring the "{I}ndian {O}cean mission 2022," floating plastic debris (>500 mu m) was collected from the {S}aya de {M}alha region using manta trawling. {T}he collected debris were quantified, classified by type, size, and weighed. {T}he associated microbiome, along with the viable bacterial communities attached to the plastic, were analyzed using 16{S} r{DNA} high-throughput sequencing and traditional molecular and microbiological techniques. {A} high concentration of plastic debris was recorded both on {S}aya de {M}alha and {N}azareth {B}ank, with 10(5) items.km(-2). {T}he mean viable bacterial count was 15,519 +/- 9340 {CFU}/g of plastic debris. {N}ine bacterial phyla were identified, with {F}irmicutes (58 % of the total) and {P}roteobacteria (42 %) being the dominant groups. {T}he bacterial diversity on the plastic was measured at 0.92, including coral pathogens, such as {A}cinetobacter (27 %), {P}sychrobacter (2 %), and {P}seudomonas (2 %). {I}n addition, probiotic bacteria such as {E}xiguobacterium (58 %), {R}heinheimera (1 %), and {I}diomarina (1 %) were also detected. {T}his preliminary study states the presence of both pathogenic and probiotic coral-associated fixed to plastic. {F}urther research is needed to confirm their direct effect on coral reef disease. {N}evertheless, these findings add to the growing evidence of the widespread presence of plastic debris floating in the region.},
