Antibiotic-resistant bacteria
-
It's always good if the use of antibiotics can be avoided, to keep harmful bacteria from developing a resistance to them. A new wound-treatment spray could help, as it kills bacteria using peptides that occur naturally in our bodies.
-
Staphylococcus aureus is a common bacterium in humans, but it can turn nasty. A new clinical trial has shown that a probiotic can selectively cut populations of the bug in humans, reducing the risk of infection without the hazards of antibiotics.
-
A case study has tracked, for the first time, the movement of antibiotic-resistant bacteria from a patient's gut microbiome to their lungs. The research presents the first direct evidence of this transmission pathway taking place in hospital patients.
-
Drugs given to the whole body can be too much of a shotgun approach, damaging cells that aren’t meant to be targeted. A new study has found that cloaking drugs inside red blood cells could help guide powerful but toxic antibiotics to target bacteria.
-
Urinary tract infections (UTIs) are common and treatable, but there can be complications, especially when the bacteria become drug resistant. Now, a new drug combo has shown promise in a Phase 3 clinical trial.
-
The rise of drug-resistant bacteria calls for new approaches to how doctors protect against bone infection after joint replacements, and a potent new form of bone cement is poised to take up the fight.
-
Scientists have identified a toxin used by bacteria to kill others through a unique mechanism. It's the first found to directly target RNA in what the team describes as “a total assault on the cell,” which could lead to a new class of antibiotics.
-
Bacteria are fast developing resistance to our best drugs, leaving us poised on the edge of a major health crisis. But a new antibiotic has shown promise against several key “superbugs,” while minimizing damage against good bacteria in the body.
-
A pair of new studies from researchers in the UK offer a warning to dog owners who frequently feed their pets raw meat. The research indicates pets fed raw meat diets were more likely to harbor antibiotic-resistant bacteria.
-
Scientists at Brown University have developed a new material that can release drugs only when pathogenic bacteria are around. When used as a bandage, the hydrogel could deliver medication on-demand when infection begins to take hold.
-
Bacteria are great at resisting antibiotics, but they can’t fight tiny drills ripping them open. Researchers have now demonstrated next-generation molecular drills that are activated by blue light and could revolutionize the fight against superbugs.
-
Algorithms have helped uncover a new antibiotic that shows promise against some nasty bacteria, using a novel mode of attack that should be hard for them to develop resistance to. Most importantly it could unlock a whole new arsenal of antibiotics.
