Researchers discover genes that help bacteria prevent treatment: Study

IANS  |  New York 

Researchers have discovered two genes that make some strains of harmful resistant to treatment by copper, which is a powerful and frequently used antibacterial agent, says a new study.

The discovery showed that Staphyloccocus aureus bacteria, which is highly resistant to antibiotics, can acquire additional genes that promote and antibacterial resistance and may open new paths for the development of antibacterial drugs.

The study, conducted by the in the US, showed the two genes, named copB and copL, in some strains of protect the germs from copper.

The genes may promote the survival of in settings, such as in hospitals, that could lead to or they may lead to strains with higher copper resistance.

Recently, hospitals began using it against found on medical instruments and other surfaces. It has also been used for thousands of years to sterilise wounds and drinking water.

But the two newly discovered genes encode proteins that help remove copper from S. aureus cells and prevent it from entering.

The findings, published in the Journal of Biological Chemistry, revealed that some strains of S. aureus have newly acquired genes embedded in their genome in pieces of DNA called transposons.

Transposons aid in the spread of genes that can give rise to bacteria that are resistant to and more likely to cause The newly discovered genes are encoded within a transposon, said the study.
