The authors generalize their interpretation to other cases where antibiotic resistance depends on export, but it will be interesting to find out whether it could in fact apply more widely, to include the other major mechanisms of resistance: target modification and the synthesis of antibiotics via ...
Antibiotics are medications used to treat bacterial infections. In order to be effective, an antibiotic must target a process that takes place in bacteria without harming human cells, thereby killing bacteria without becoming toxic to humans.
the layer that holds the whole cell together; glycopeptide antibiotics also go to work on the structure of a cell wall, specifically preventing Gram-positive bacteria from being able to build new walls -- and a cell can't live without the wall that holds all of its innards...

Each time antibiotics would force the infection to retreat. Each time it came roaring back. In the summer of 2020, the bacteria flooding Cole’s bloodstream stopped responding to antibiotics. She was running out of time. Her doctors decided they had to try a different approach, and asked the...
Antibiotics are drugs which target bacterial cells. They interfere with the normal functioning of the bacterial cell and function by disrupting their cellular processes. One of the ways it is achieved is by inhibiting vital enzymes which help the bacteria to survive....
Netter MD School of Medicine at Quinnipiac University in North Haven, Conn., was not involved with the study but was familiar with the findings. She said, "Bacteria don't want to be killed. When we try to kill them with antibiotics, they are going to fight back. It's an ongoing ...
Until recently, there was limited knowledge and awareness about the effects of current antibiotics on an individual’s health via the collateral damage of the drug on the bacteria that normally live on or in healthy humans (i.e., our microbiota). These organisms - their genes, metabolites,...
Current tests are constrained by bacterial growth rates, as they examine the effect of antibiotics on the growth of bacteria colonies cultivated from patient samples. However, the two to three days this takes to produce results can cause problems. David Livermore, medical microbiologist at ...
If staph bacteria are confirmed, another test called a sensitivity test can be run to see which antibiotics will kill the bacteria. Golden Staph: What It Looks Like Staphylococcus aureusis fairly small, even by bacterial standards. It's about 40 times smaller than the width of a human hair....
