“…For example, PE collected from the estuary was observed with a higher ARG abundance than PP (Guo et al, 2020), which was similar to those observed in leachate microcosm (Su et al, 2021). Without regarding the abundance, ARG composition on microplastics was distinct from the surrounding environment (Wang et al, 2020a;Wu et al, 2019;Yang et al, 2020a).…”

“…While, a field incubation experiment found that microplastics usurally had lower diversity and richness of ARGs compared with water using HT-PCR (Yang et al, 2020a). Microplastics collected from the urban river with unknowing incubation time also showed lower relative abundances of 25 ARGs than those in water samples via qPCR (Wang et al, 2020a). Polymer types also exhibited different performances on the ARG enrichment on microplastics from the aquatic environment.…”

“…Ten papers related to ARGs on microplastics in the aquatic environment were summarized, among which six studies showed that microplastics enriched ARGs (Guo et al, 2020;Lu et al, 2019;Raju et al, 2018;Wang et al, 2020a;Wang et al, 2020b;Wu et al, 2019;Yang et al, 2019b) (Table 1). It was also found that most studies focused on ARGs on the microplastics in the waterbody, not the sediment, which might be attributed to the difficulties in the recovery and identification of microplastic biofilm in benthic conditions (Van Cauwenberghe et al, 2015).…”

“…Over the past decade, research effort has been undertaken on exploring the pathogen risk of microplastics in various aquatic ecosystems, such as coastal water [17], bays [18], estuaries [19], urban rivers [20]. Some studies have suggested that microplastics can serve as vectors to increase the survival of potential pathogens, and transfer pathogens to marine organisms or formerly unaffected ecosystems [21].…”

Assessing the Risks of Potential Bacterial Pathogens Attaching to Different Microplastics during the Summer–Autumn Period in a Mariculture Cage

et al. 2021

As microplastic pollution continues to increase, an emerging threat is the potential for microplastics to act as novel substrates and/or carriers for pathogens. This is of particular concern for aquatic product safety given the growing evidence of microplastic ingestion by aquaculture species. However, the potential risks of pathogens associated with microplastics in mariculture remain poorly understood. Here, an in situ incubation experiment involving three typical microplastics including polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP) was conducted during the summer–autumn period in a mariculture cage. The identification of potential pathogens based on the 16S rRNA gene amplicon sequencing and a custom-made database for pathogenic bacteria involved in aquatic environments, was performed to assess the risks of different microplastics attaching potential pathogens. The enrichment of pathogens was not observed in microplastic-associated communities when compared with free-living and particle-attached communities in surrounding seawater. Despite the lower relative abundance, pathogens showed different preferences for three microplastic substrates, of which PET was the most favored by pathogens, especially potentially pathogenic members of Vibrio, Tenacibaculum, and Escherichia. Moreover, the colonization of these pathogens on microplastics was strongly affected by environmental factors (e.g., temperature, nitrite). Our results provide insights into the ecological risks of microplastics in mariculture industry.
