New studies have shown that the micrene genes can be a superior host of the dull biofilm generated by bacteria to protect themselves by bacteria, contributing to the spread of dangerous antibiotic resistant superbugs.
Neila Gross, a Ph.D. in Ph.D., Ph.D., Ph.D. Science, Boston University, said, “Fine plastics are the same as a raft. Bacteria can’t swim along the river on their own, but if you take biofilms with a lot of plastics, you can spread to various environments.
Bio film is a protected three -dimensional structure created by bacteria in its own waste. Like gloves and insulating houses, OOZY GOO allows bacteria to live, thrive and replicate safely.
Many surfaces can host biofilms, but the plaque of teeth is biofilm. Plastics seem to provide a particularly strong combination of attracting the most bacteria.
Bio film actually works well and can increase antibiotic resistance to hundreds to thousands of times more than normal, Zaman said.
“Bio film is very sticky and bacteria can react to enemy antibacterial assaults such as antibiotics, so it’s very unpleasant to get off. If that happens, the problem becomes very difficult to manage. ”Muhammad Zaman, A, said. Howard Hughes Medical Research Institute Professor Boston University’s Biomedical Engineering and Global Health Professor.
Zaman said, “We knew that the connection between microplastics and antibacterial resistance is practical and not limited to single antibiotics. “It affects a wide range of antibiotics that are widely used and actually related.”
More powerful, faster and antibiotic resistance
This study published in the journal on Tuesday Applied environment and microbiologyIt is a potential dangerous bacteria that can cause diarrhea and abdominal pain by analyzing biofilms from microplastics and glass produced by E. coli.
In the test tubes in the laboratory, researchers exposed this biofilm to four antibiotics: Cyprofloxacin, Dokshi Cycline, Fluoroquinolone and Ampicillin. Both are extensive antibiotics used to treat various types of bacterial diseases.
When E. coli biofilm was in microplastics, it was faster, larger, and more antibiotic resistance than the biofilm that grows in the glass sphere.
In fact, the speed of antibiotic resistance by E. coli grew in microplastics is so high that the test has been repeated several times using a different type of microplastics and antibiotic combinations. The result was consistent, she said.
In addition, E. coli bacteria, grown in microplastics, maintained the ability to form stronger biofilms even when they were removed from the microfluid, Gross said.
“This bacteria are not only resistant to antibiotics, but are better for making biofilms,” she said. “It is very important for the microemine to make bacteria a faster and better biofilm former.”
It’s interesting, but the result should be replicated. Shilpa Chokshi, an environmental professor at the University of Pleurce, who did not participate in this study.
“This was a laboratory study using E. coli and four antibiotics under controlled conditions, which does not completely replicate the actual complexity.” Chokshi said in the statement. “Further research is needed to evaluate whether this effect is interpreted as a human infection or environment.”
