resistance. A bacterium may naturally be resistant to the drug. One such example is the nptII gene, which is found naturally in bacteria and which produces an enzyme that inhibits the action of kanamycin in the bacterial cell. This type of natural resistance passes down through the bacterial ...
Metagenomic studies have shown that antibiotic resistance genes are ubiquitous in the environment, which has led to the suggestion that there is a high risk that these genes will spread to bacteria that cause human infections. If this is true, estimating the real risk of dissemination of resistanc...
The CDC said there are signs the percentage of Shigella bacteria cases that are resistant to a broad swath of antibiotics has begun to climb steeply around the U.S. Antimicrobial resistance happens when germs like bacteria orfungidevelop mutations and no longer respond to medicines designed to com...
Using antibiotics when they are not needed or taking the wrong antibiotic significantly contributes to antibiotic resistance. This is because antibiotics not only kill harmful bacteria, but they can also kill helpful bacteria that may protect you from the harmful bacteria. When helpful bacteria die, ...
Which bacteria are bad for you? What is bacterial vaginosis? Antibiotic resistance This colorized image (a scanning-electron micrograph) shows four spherical methicillin-resistant Staphylococcus aureus (MRSA) bacteria (purple) in the process of being “ingested” by a human neutrophil white blood...
This happens when bacteria developed the ability to survive the medications designed to kill them. 10) Antibiotic resistance is a serious threat to health, and the problem is growing. his makes finding new antibiotics very important. However, in recent decades, very few have been developed. And...
what s next correction to resistance to antibacteria1 agents foregone conc1usionThe article Resistance to Antibacterial Agents: Foregone Conclusion - What's Next?, written by Chand Wattal & Nancy Khardori, was originally published electronically on the publisher's internet portal (currently Springer...
Their ability to kill bacteria without harming the patient has saved billions of lives and made surgical procedures much safer. But after decades of overuse, their powers are fading. Some bacteria have evolved resistance, creating a growing army of superbugs, against which there is little effective...
Female Student: OK. But the question is: how do bacteria get the resistance genes? Male Student: How do they get the resistance genes?They just inherit them from the parent cell, right? Female Student: OK, yeah, that's true. They can inherit them from the parent cell, but that's not...
and then of the rest of antibiotics heralded the end of clinical bacterial infections. It is now common knowledge that such a view was fatally flawed. Simple mutations in key genes during cell division provided the bacteria with a means of escaping the action of the antibiotic (resistance). On...
