As the study showing that the molecular machinery used by bacteria to resist chemicals designing; to kill them could also help produce precursors for a new generation of nylon and other polymers. Resistance to artificial antiseptics appears to be a lucky accident for the bacteria, and it could also be useful for humans. Bacteria that are unaffected by antiseptics and antiseptic, often termed superbugs; are a growing problem, but exactly how they develop resistance is not fully understanding.
But bacterium knowing as Acinetobacter baumannii resisted chlorhexidine; a powerful hospital grade antiseptic listed by the World Health Organisation as an essential medicine. A. baumannii‘s secret weapon, they finding, is a protein called AceI; which sits on its surface and pumps out any chlorhexidine that gets inside. That was surprising, because the protein has been around for a lot longer than the antiseptic.
Resist chemicals designing
As the gene that encoding the AceI protein appearing to be the very old; but chlorhexidine was only creating in the twentieth century; So the gene can’t have the native function of protecting against chlorhexidine. It’s a side reaction that is fortunate for the bacteria. Study also looking other compounds are transporting by AceI and its relations; collectively known as Proteobacterial Antimicrobial Compound Efflux (PACE) proteins. This finally finding that that PACE proteins are likely to be future engines of antimicrobial resistance.
However, that their ability to transport a wide range of substances means; that they could be effectively repurposing in an industrial context to catalyse the manufacture of petroleum-free polymers such as nylon. These PACE proteins are very promiscuous in the compounds; that they transport and are a likely cause of future resistance to new antimicrobials that are currently being developing.
Treatable normal antibiotics
As Acinetobacter baumannii was once treatable with normal antibiotics but is now one of the most worrying superbugs threatening the medical system. It has been particularly associating with infections of military personnel injuring in Iraq and Afghanistan. Its ability to survive on disinfecting artificial surfaces for long periods has allowing it to thrive and spread through the military and into the civilian medical system.
The study finally stating that the antiseptics and disinfectants are a key defence using to control the spread of these bacteria in hospitals particularly. Such work is important in ensuring that we can continue to use successfully this disinfectant to reduce rates of infection in hospitals.
