Plastic pollution is a global emerging concern, but in the Arctic Ocean, role of plastisphere as potential carrier pathogens and antibiotic-resistant bacteria unknown yet. An initial assessment spread these target through their colonization plastic particles, attributed to micro-sized fraction (less than 5 mm, named microplastics, MPs), was carried out across 75° N transect (Greenland Sea). To fill knowledge gaps regarding bacterial community associated withmicroplastics (MPs)—belonging so-called “plastisphere”—and risks related spread, our study focused on abundance taxonomic composition plastisphere, including pathogenic bacteria, using culture-dependent approach. MPs particles were collected Manta net, decimal dilutions cultured Marine agar plates estimate culturable heterotrophic bacteria. For search species (Escherichia coli, Enterococcus spp., Salmonella potentially Vibrio Staphylococcus aureus), small volumes inoculated into selective culture media aspread plate directly or after enrichment. Screening antibiotic susceptibility profiles isolates performed assess presence The dominated by members phyla Gammaproteobacteria Actinobacteria, with assigned genera Psychrobacter, Pseudoalteromonas, Shewanella, Arthrobacter. Selective enrichments resulted detection pathogens, mostly identified Vibrios examined samples. pointed that multiple also isolated, suggesting need shed light human animal health deriving from remote cold regions well.
