Microbial biofilms on environmental plastic pollution can serve as a reservoir for both pathogenic and commensal bacteria. Associating with this 'plastisphere', provides mechanism the wider dissemination of pathogens within environment greater potential human exposure. For to bind waste they need be in close contact it; therefore, understanding how rapidly plastics temporal colonisation dynamics continual cycling between plastisphere are important factors quantifying persistence pathogens. Using simulated conditions, we demonstrate that E. coli O157 colonise (within 30 min) persist extended periods (at least 21 days), at concentrations sufficient cause infection. Importantly, repeated dissociation cycles from leads an enhanced capacity emergence variants increased virulence traits, including improved biofilm formation antibiotic tolerance. This phenotypic adaptation surfaces could selecting more persistent virulent strains pathogens, hence increase co-pollutant risks associated pollution.

ABSTRACT Microplastics (MPs) have emerged as a significant environmental pollutant with profound implications for public health, particularly substrates to facilitate bacterial antimicrobial resistance (AMR). Recently, studies shown that MPs may accommodate biofilm communities, chemical contaminants, and genetic material containing AMR genes. This study investigated the effects of MP concentration, composition, size on development multidrug in Escherichia coli . Specifically, we exposed E. varying concentrations different types, including polyethylene, polystyrene, polypropylene, across range sizes (3–10, 10–50, 500 µm). Results indicated cells attached had elevated (in Notably, exhibited higher propensity facilitating than control such glass, likely due their hydrophobicity, greater adsorption capacities, surface chemistries. found bacteria passaged formed stronger biofilms once were removed, which was associated changes motility.

Our highlights importance developing effective strategies address challenges posed by MPs. IMPORTANCE Antimicrobial (AMR) is one world's most pressing global health crises.

Microplastics and antibiotics are two significant emerging pollutants found together in water bodies, raising concerns about their mutual effects. This review delves into how microplastics interact aqueous environments the ecotoxicological implications of such interactions, particularly bioavailability prevalence antibiotic-resistance genes. It outlines that attach to primarily through hydrophobic, hydrogen-bonding, electrostatic interactions. Other bonds, comprising halogen bonding, cation−π interaction, negative charge-assisted hydrogen may also be involved better explain antibiotic adsorption patterns.

Plasma treatment has emerged as a promising tool for manipulating plant microbiomes and metabolites. This review explores the diverse applications effects of plasma on these biological systems. It is hypothesized that will not induce substantial changes in composition or concentration We delve into mechanisms by which can regulate microbial communities, enhance antimicrobial activity, recruit beneficial microbes to mitigate stress. Furthermore, we discuss optimization parameters effective microbiome interaction role plasmids plant-microbe interactions. By characterizing plasmidome responses exposure investigating transcriptional metabolomic shifts, provide insights potential engineering The presented herein demonstrates induces both community metabolite levels, thereby refuting our initial hypothesis. Finally, integrate plasmidome, transcriptome, metabolome data develop comprehensive understanding plasma's biology explore future perspectives agricultural applications.

Plastic pollution in the ocean is a global environmental hazard aggravated by poor management of plastic waste and growth annual consumption. Microbial communities colonizing plastic's surface, plastisphere, has gained interest resulting numerous efforts to characterize plastisphere. However, there are insufficient studies deciphering underlying metabolic processes governing function plastisphere they reside upon. Here, we collected seawater samples from Ashmore Reef Australia examine planktonic microbes associated biofilm (PAB) investigate ecological impact, pathogenic potential, degradation capabilities PAB Reef, as well role impact bacteriophages on PAB. Using high-throughput metagenomic sequencing, demonstrated distinct microbial between Similar numbers bacteria were found both sample types, yet select for different pathogen populations.
