Microbes on plastic in rivers: resistance to pathogens and resistance to antibiotics Plastic has become an invisible part of our everyday life, due to its influx into the environment and possible benefits for human health are lost. 'This is the investigation. In the experiment, half of the transparent plastic was new, and the other half was heated in an oven for six months to simulate laying out or vibrating.

After this, the microbial spores detected on the plastic of the trees were compared with those that were on the control surfaces (wooden sticks) and in the river water. It turned out that the stains of plastic and wood were replaced by potentially pathogenic microbes, and their storage was disrupted by microorganisms in river water.

Plastic waste found in rivers is an ideal medium for the growth of dangerous microbes that resist antibiotics. Microbial pathogens that find their homes on plastic surfaces near rivers can harbor potentially pathogenic microorganisms and serve as reservoirs of resistance genes to antimicrobial drugs. The importance of this finding lies in the context of potential threats to the environment posed by new and discarded plastic materials..

Among the identification of potential pathogens in plastic and wood particles were the bacteria Pseudomonas aeruginosa, Acinetobacter and Aeromonas, known as “mentally pathogenic”. These bacteria can become a significant risk for individuals with a weakened immune system. At the same time, the river water contained potential pathogens for humans, such as Escherichia, Salmonella, Klebsia and Streptococcus.

Recently, among them Vinko Zazhelovic, Elizabeth Wellington, Joseph Christ-Oleza, and their colleagues, studied in detail the microbial spores on the surfaces of polyethylene spittle, after their imprisonment in the Sow River in Vel of Britain.

The test was carried out at a distance of one kilometer downstream from the wastewater treatment plant, lasting seven days in the summer of 2020..

The results are based on important differences in pathogens and antimicrobial resistance genes, which can be caused by both new and degraded plastic materials.. This information is key to understanding the flow of plastic into the river ecosystem and highlights the need to make changes to change the flow of water into the river..
