In 2019, infections related to antibiotic resistance are estimated to have killed 2.7 million people worldwide.By 2050 they are predicted to cause 10 million deaths worldwide, according to the study, published in the journal Microbiome.When plastic ends up in water its surface is overrun within minutes by nearby microbes.The researchers submerged samples for a week in the River Sowe in Warwickshire and West Midlands England, downstream from a wastewater treatment plant.They found significant differences in the microbe communities depending on the material sampled.Water worries Wastewater is required to be treated and disinfected to reduce microbial hazards and any adverse impacts they might have on human and environmental health.But the water samples that the researchers collected in February of 2020 harboured human pathogens such as Salmonella, Escheria most commonly known as E.Coli, and Streptococcus responsible for strep throat.That underscores &quot;the pressing need for stricter monitoring of wastewater treatment plants,&quot; said Zadjelovic.Meanwhile, the plastic and wood samples attracted &quot;opportunistic&quot; bacteria such as Pseudomonas aeruginosa and aeromonas, known to pose risk to people with compromised immune systems.P.aeruginosa, which causes infections in hospital patients, was found to be nearly three times more abundant on &quot;weathered plastic&quot; that the researchers manipulated to resemble the way plastic breaks down in nature, when compared to the wood.That weathered plastic also showed a greater abundance of the genes responsible for antibiotic resistance.In recent months, British water companies have come under fire over the pumping of raw sewage into the UK&#x27;s waterways and the underreporting of pollution events, provoking widespread public anger.Rivers are the main way plastic enters the world&#x27;s oceans, channelling anywhere between 3.5 thousand tonnes to 2.41 million tonnes of the manmade material to the sea annually.lap/klm/jj<div>© Agence France-Presse</div><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2479349" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>
