Adree Khondker and Maikel Rheinstadter discuss how bacteria escape being killed by polymyxin antibiotics. Touching on their recent Communications Biology paper, they elaborate on the mechanism by which the bacterial membrane becomes resistant and on future directions to take in order to understand ...
Given ongoing concerns that even bacteria likeKlebsiellaandEnterobacter—which are found in the environment and in healthy stomachs—are becoming increasingly resistant to last-resort antibiotics, the researchers set out to find some answers. Their report, published Sept. 17 inScience Translational Medicin...
Some bacteria are more resistant to antibiotics than others, with so-called gram-negative bacteria being particularly resilient because they have an extra membrane to armor themselves. They also have a sophisticated plumbing system in the form of a three-part protein complex – MacAB-TolC – ...
This is a computer model of how bacteria traveling through the bloodstream clump together, which may explain how bloodstream infections resist antibiotics. Credit: University of Michigan New research may help explain why hundreds of thousands of Americans a year get sick – and tens of thousands die...
Antibiotics are anti-microbial drugs that are used to stop the growth of bacteria. Antibiotics are not effective against any kind of viral infections, such as flu, cold-cough, etc. Antibiotics are classified into two types- broad-spectrum antibiotic and narrow-spectrum antibiotic. The first ...
RESEARCH HIGHLIGHTS THIS WEEK compounds could have been important for kicking off the chemistry that led to life on Earth, the researchers say. Astrophys. J. Lett. 792, L2 (2014) MICROBIOLOGY How Salmonella bounces back Two groups have shown how Salmonella bacteria can resist antibiotics. Dirk ...
Why are some bacteria intrinsically resistant to some antibiotics? Explain how some bacteria are able to resist penicillin action. Briefly describe three factors that are contributing to the problem of antibiotic resistance. What does it mean for a bacterium ...
Some bacteria can naturally resist certain kinds of antibiotics. Others can become resistant if their genes change or they get drug-resistant genes from other bacteria. The longer and more often antibiotics are used, the less effective they are against those bacteria. ...
This expedites the discovery of new antibiotics and helps repurpose existing drugs to combat resistant bacteria. In this review, we explore the integration of AI across three critical domains essential for curbing the escalation of AMR: (1) clinical diagnostics, (2) AMR surveillance, and (3) ...
By analyzing thousands of bacterial samples directly from humans rather than in lab settings, researchers identified crucial genetic mutations that help these bacteria resist antibiotics and evade the immune system. This could lead to improved methods for preventing, diagnosing, and treating infections. ...
