Amid growing concerns that antibiotics currently in use may turn ineffective in fighting bacteria, Israeli scientists have developed a substance that melts the germ's cell surface rapidly, preventing it from producing a new generation of bugs that have adapted to the medicine.

The reason for growing bacterial resistance is that existing antibiotic strains attack only certain "targets" in the germ, leaving active remnants, researchers said.

This enables the next generation of germs to receive information from the injured ones and mutates, rendering the antibiotic ineffective, they said.

The main damage is caused by the wrong use of antibiotics and also if the entire prescribed dose is not consumed, germs remain in the body and quickly learn how to become resistant to the substance, the scientists noted.

In view of this, scientists at the Weizmann Institute in Israel, headed by Professor Yehiel Shai, have designed a more powerful antibiotic, daily Ha'aretz reported.
