antibiotic

A new antibiotic has been developed to kill the bacteria that shows resistance to most of the available medicines, according to research published in a science magazine, Nature.

Different types of antibiotics have their unique way of killing the bacteria while most of them work by damaging the cell wall of the bacteria. The other way is to stop the protein formation necessary for bacteria to live, or altering their DNA formation.

The problem scientists and doctors are facing is the resistance that bacterias develop against the drugs making almost impossible to kill them. Physicians come across numerous cases where familiar and easy to treat infections transform into deadly trauma.

The key is in the mechanism that antibiotics follow to work against the germs, the researchers have devised a new approach towards killing the bacterias that makes the drug different and more potent in comparison to other medicines available in the market for the similar purpose.

Thanks to the researchers, the newly developed drug uses a sneaky and unconventional strategy. It restrains a pivotal enzyme in the cell membrane that aids the bacteria in the production of proteins. The enzyme gets blocked after some time, and the protein that already collected inside the cell membrane causes it to burst ultimately killing the bacterial cell.

Till now, tests have been conducted on mice and in cultured cells, the drug has killed a variety of gram-negative and positive bacterias including E. coli and Pseudomonas aeruginosa.

It will take some time when the antibiotic finally lands at pharmaceutical stores. It remains to see that how bacteria tackles the drug in the long-term, most probably they will eventually develop resistance against it too as they are famous for, but for some time it will be a great relief for the patients.
