We have special white blood cells that attack harmful bacteria. Even if symptoms do occur, our immune system can usually cope and fight off the infection. There are occasions, however, when it is all too much and some help is needed...from antibiotics. Alexander Fleming Alexander Fleming disc...
Physical insights into permeation of and resistance to antibiotics in bacteria. Bacteria can resist antibiotics simply by hindering physical access to the interior, where in general antibiotic targets are located. Gram-negative bacteri... M Ceccarelli,P Ruggerone - 《Current Drug Targets》 被引量:...
Bacteria typically attach to a host and release toxins that attack cells in the immune system by disablingmitochondria, or a cell's source of power. The harmful organisms can also rapidly multiply to disrupt normal tissue functions or cause immune system functions to become toxic. Focusing on Cel...
"Our discovery prevents infection without building up antibiotic resistance. As such, it might even be preferable to construct treatments based on molecular tweezers rather than antibiotics," says Prof. Jelinek, who is also Ben-Gurion University's Vice President of Research...
Inadequate development of new antibiotics and rising rates of resistance by bacteria to existing antimicrobials are dual forces pushing the world ever closer to a post-antibiotic era.
With the modified agar plate CombiANT it is possible to do high-speed tests in order to see how bacteria react to different combinations of antibiotics.Researchers at Uppsala University have dev…
Now, the Hebrew University researchers, led by Prof. Gadi Glaser of the Faculty of Medicine and Prof. Nathalie Balaban of the Racah Institute of Physics, have been able to demonstrate how this comes about. Their research showed that whenantibioticsattack these bacteria, the HipA toxin disrupts ...
Antibiotic-resistant bacteria from livestock pose a deadly risk to people. But the farm lobby won't let scientists track the danger
It would be unwise to rely on new antibiotics to solve the problem. The rate at which resistance emerges is accelerating. Some new drugs last only two years before bacteria devise countermeasures. When new antibiotics do arrive, doctors often hoard them, prescribing them only grudgingly and for ...
How do macrophages protect your body from infection? What methods do predatory bacteria use to attack other bacteria? How do killer T-cells destroy viruses? How are staphylococcus species pyogenic? How can antibiotics stop bacterial infections? How might a bacteriophage affect the virulence of a ba...
