Abstract Background Antibiotics and microplastics are two major aquatic pollutants that have been associated to antibiotic resistance selection in the environment considered a risk human health. However, little is known about interaction of these at environmental concentrations response microbial communities plastisphere sub-lethal pollution. Here, we describe bacterial dynamics underlying this surface water bacteria community, resistome mobilome level using combination methods (next-generation sequencing qPCR), targets (16S rRNA gene, pre-clinical clinical class 1 integron cassettes metagenomes), technologies (short long read sequencing), assembly approaches (non-assembled reads, genome assembly, bacteriophage plasmid assembly). Results Our results show shift community antibiotics microbiome compared subpopulations respond differently microplastic The showed an increased tolerance selected different (ARB) genes (ARGs). Several metagenome assembled genomes (MAGs) derived from antibiotic-exposed contained ARGs, virulence factors, involved conjugation. These include Comamonas, Chryseobacterium, opportunistic pathogen Stenotrophomonas maltophilia , other MAGs belonging genera infections, such as Achromobacter. abundance integron-associated ciprofloxacin gene aac(6’)-Ib-cr under exposure both freshwater plastisphere. Regarding mobilome, although no significant changes ARG load integrons plasmids were observed polluted samples, identified three ARG-containing viral contigs integrated into prophages. Conclusions This study illustrates how selective nature influences pressure. here help define role its impact on maintenance with anthropogenic pollutants. research highlights need evaluate complex scenarios combined stresses.

The Environmental Impact of E-Waste Microplastics: A Systematic Review and Analysis Based on the Driver–Pressure–State–Impact–Response (DPSIR) Framework

Environments, Год журнала: 2024, Номер 11(2), С. 30 - 30

Опубликована: Фев. 3, 2024

Microplastics resulting from the fragmentation of plastics in electronic waste (e-waste) are an emerging but understudied environmental concern. This systematic review employs a Driver–Pressure–State–Impact–Response (DPSIR) framework to investigate sources, prevalence, and effects e-waste microplastics, identifying knowledge gaps. The available literature on microplastics was retrieved Scopus Web Science (n = 24), trends electrical equipment were European Union databases. growing incorporation electronics into daily life results global annual growth rate 3–4% for e-waste, which only 17.4% is collected recycling. E-waste frequently found soils near disposal or disassembly facilities, potentially leaching hazardous metals (e.g., Pb) organic compounds flame retardants). These contaminate food chain can have adverse soil gut microbiome, organisms, human health, either independently associated with other chemicals. Responses include implementation regulations, improvement management systems, mitigation measures. Despite these concerns, topic remains limited, emphasizing need additional research identification their toxicity.

Elevated levels of antibiotic resistance genes as a factor of human‐caused global environmental change

Global Change Biology, Год журнала: 2024, Номер 30(7)

Опубликована: Июль 1, 2024

Antibiotic resistance genes (ARGs) have moved into focus as a critically important response variable in global change biology, given the increasing environmental and human health threat posed by these genes. However, we propose that elevated levels of ARGs should also be considered factor change, not just response. We provide evidence are factor, since this phenomenon is linked to activity, occurs globally, affects biota. explain why could rather than organisms containing them; highlight difference between presence antibiotics, which necessarily caused multiple factors. Importantly, shifting perspective opens new avenues research, where can experimental treatment. This includes asking questions about how ARG interact with other factors, or influence ecosystem processes, biodiversity trophic relationships. Global biology stands profit from framing terms capturing more completely real extent impacts on planet.
