Abundance and antibiotic susceptibility of Vibrio spp. isolated from microplastics

Identification of Microorganisms Related to Microplastics

AI summary · Read the abstract

Plastic debris in aquatic environments attracts diverse microbial communities that differ from those in surrounding water, with these plastisphere microorganisms influencing both the degradation fate of plastics and the dispersal of potentially pathogenic or plastic-degrading microbes. Identifying which microorganisms colonize microplastics is essential for understanding both environmental risks and potential bioremediation opportunities.

Identification of Microorganisms Related to Microplastics

AI summary · Read the abstract

Plastic debris in aquatic environments is rapidly colonized by diverse microbial communities, with phototrophic organisms like cyanobacteria and diatoms attaching first before being succeeded by proteobacteria, forming what is known as the plastisphere. These microbial biofilms can alter plastic degradation rates and potentially harbor and transport pathogenic organisms, adding a biological dimension to microplastic pollution risks.

Microbial Relationship of Marine Microplastics

AI summary · Read the abstract

Researchers examined how microplastics in the ocean interact with microbial communities, finding that plastic surfaces attract and harbor unique assemblages of bacteria — a concern because these 'plastisphere' microbes can spread pathogens and antibiotic-resistant genes through marine food chains.

Microplastics as a Carrier of Antibiotic Resistance Genes: A Revision of Literature

AI summary · Read the abstract

Researchers review evidence that microplastics act as carriers and hotspots for antibiotic resistance genes, influencing bacterial community composition in the environment and potentially accelerating the spread of antibiotic resistance — a dual threat to ecosystem and human health.
