Plastiome
Plastiome refers to the plastisphere-enriched mobile resistome found in aquatic environments.[1] With persistence of plastics and microplastics in the environment, these act as reservoirs for microbial communities and antibiotic resistance genes,[2] fostering the formation of a mobile resistome encompassing diverse antibiotic, biocide/metal resistance genes, and mobile genetic elements. This collective genetic repertoire, plastome, can potentially perpetuate environmental antimicrobial resistance (AMR).[1] This plastiome in fresh water environments has shown more than three times higher enrichment of antibiotics on microplastics than those in water,[1] and it has been reported that some of the identified taxa attached to the plastics could be potential pathogens and pose a risk to human health and the environment.[3]
Plastiome in Environment
Microplastics are persistent, very mobile and hard to remove from nature.[4][5] Hence, these plastiomes could perpetuate harmful multidrug resistance genes in microbes in the environment. Plastiomes were identified and reported in two rivers near Tokyo, Japan.[6]
Plastiome and Health Risk
The health risks of plastiome can be recognized from four aspects, 1). pathogens residing within the plastisphere[7], 2). potential acquisition of antimicrobial resistance through horizontal gene transfer[8], 3). increased tolerance to antibiotics[9], and 4). trophic transfer through food webs. Microplastics trophic transfer through food webs has been researched and well documented[10][11][12]. Further the evidence indicates that the ratio of pathogens to total bacteria[2], as well as the presence of resistance genes[1], is significantly higher in the plastisphere compared to surrounding water. This raises concerns that the plastiome poses additional health risks associated with antimicrobial resistance in aquatic environments.
