New Strategy Likely To Surmount Superbugs’ Drug Resistance; Say Scientists

Resistance of Antibiotic, which is defined by the lack of vulnerability of bacteria to drugs that were previously effective, has at present, become quite a problem all over the world. In fact, scientists are calling it a global crisis. They are coming out with new strategies, which range from using viruses that kill bacteria to compounds that are derived from cranberries for countering these super-bacteria or bacteria that are resistant to drugs.

In the light of this, most of the latest research linked with antibiotic resistance is dealing with the development of new pharmaceutical compounds, or they are coming out with altogether new methodology of treatments, which are based on an entirely new genre of antibiotics hitherto unknown.

However, researchers at the Emory Antibiotic Resistance Center in Emory University School of Medicine of Atlanta, Georgia are of the opinion that old drugs can be effective when used in newer ways in the fight against these superbugs.

They have found that bacteria have grown, which is now termed as ‘heteroresistance’ that helps them to fight antibiotics. Though they are still struggling to find out the exact reason behind this new phenomenon, they have found heteroresistance to be a new phenomenon, by the virtue of which a subpopulation within a larger population of bacteria develops qualities of resistance to antibiotics, to which other bacteria belonging to the same populace will respond.

Scientists, however, believe that if and when they are able to successfully identify heteroresistance, it will help them to identify the most effective combination of antibiotics when it comes to defeating a combined population of drug-resistant and susceptible bacteria.

The researchers have used various samples for identification of multidrug-resistant bacteria. Of them, more than 85% turned out to be resistant to at least two different types of antibiotics.

However, these two types of antibiotics that this 85% was resistant to, were combined, and the combination turned out to be more effective in terminating the bacteria.
