The story of antibiotic resistant bacteria is really a tale of good versus evil. In this tale, the bacteria are most definitely the bad guy and the antibiotics are the good guy. While we would love for the good guy to win in every case, that's not always true when it comes to bacter...
Because a generation for a bacterium is extremely short (no more than one day, and often less than an hour), such evolution can occur very quickly. The result is that existing antibiotics lose their effectiveness over time.Rubin, Paul H...
evolution is this vague idea that they have. It’s something people have heard of conceptually, but they don’t get to see it happen with their own eyes. What this work does is to offer a demonstration
killing 1.5m people. It can be cured if treated with the right antibiotics, but treatment is lengthy and many people most at risk lack access to adequate healthcare. Drug-resistant TB can develop when people do
In recent years, we have seen antimicrobial resistance rapidly emerge at a global scale and spread from one country to the other faster than previously thought. Superbugs and multidrug-resistant bacteria are endemic in many parts of the world. There is no question that the widespread use, overuse...
“Our findings,” Brady stated, “suggest macolacin could potentially be developed into a drug to be deployed against some of the most troubling multidrug-resistant pathogens.” In another study, Brady’s lab used similar methods to explore a different class of antibiotics, called menaquinone-bindi...
Worldwide, resistance to antibiotics is on the rise. In order to understand why bacteria are becoming immune to previously well-functioning drugs, scientists are penetrating ever deeper into the molecular structure of cells. A research group at Martin Lu
Antibiotic-resistant bacteria as pollution indicators It has emerged from many studies that antibiotic-resistant and multiple-antibiotic-resistant bacteria(MARB) have become increasingly widespread, primarily due to overuse of antibiotics in clinical therapeutics and inlivestockgrowth promotion. The sources ...
Plasmids are thought to play a key role in bacterial evolution by acting as vehicles for horizontal gene transfer, but the role of plasmids as catalysts of gene evolution remains unexplored. We challenged populations of Escherichia coli carrying the blaT
