"This groundbreaking work signifies a paradigm shift in antibiotic discovery and indeed in drug discovery more generally," said researcher Roy Kishony.
At least 700,000 people die each year from drug-resistant infections.
There is an urgent need for new antibiotics as more bacteria become resistant to existing drugs.
"Inappropriate prescribing of antibiotics is a major public health problem, as it contributes to antibiotic resistance," experts warned.
According to the World Heath Organization, antibiotic resistance is an "increasingly serious threat to global public health that requires action across all government sectors and society."
This enables germs to go under the radar and avoid being picked up by drugs.
The bacteria, known as Pseudomonas aeruginosa, is found widely in the environment although infections usually occur in hospitals among people with weakened immune systems.
Scientists tested the drug against antibiotic-resistant bacteria, with promising results.
Antibiotic resistance is one of the "biggest threats to global health, food security, and development today" according to the World Health Organization.
Around 700,000 people die every year as a result of infections caused by antibiotic-resistant bacteria.
Researchers hope to harness the body's own defenses to fight potentially deadly bacteria.
Antibiotic resistance is one of the biggest threats to global health, food security and development today.
Experiments on the International Space Station have shown how bacteria can effectively defend itself.
When treatments run longer than necessary, patients are put at unnecessary risk of developing antibiotics resistance, the authors explain.
World Health Organization says decreased condom use and increased travel is leading to drug-resistant gonorrhoea
Scientists have used a peptide from Komodo dragon blood to create a drug that helps wound healing in mice.
Just as the World Health Organization releases its first-ever list of such pathogens, a new study reveals an alarming spike in antibiotic-resistant bacterial infections among children. And infectious disease experts are scared.
