Scientists Develop Drug to Replace Antibiotics

Nov 06, 2014

Scientists have created the first antibiotic-free drug to treat bacterial infections in a major development in combatting drug-resistance, according to The Times.

A small patient trial showed that the new treatment was effective at eradicating the MRSA superbug which is resistant to most antibiotics. The drug is already available as a cream for skin infections and researchers hope to create a pill or an injectable version of it in the next five years.

Antibiotics have been one of the most important drugs since the invention of penicillin almost 90 years ago. But the World Health Organization has repeatedly warned of the threat of antimicrobial resistance, saying "a post-antibiotic era - in which common infections and minor injuries can kill" is a very real possibility in the 21st century.

But scientists say this new technology is less prone to resistance than antibiotics because the treatment attacks infections in a completely different way. The treatment uses enzymes called endolysins — naturally occurring viruses that attack certain bacterial species but leave beneficial microbes alone.

Mark Offerhaus, the Chief Executive of the Dutch biotech firm Micreos which is leading the research, said the development of the new drug marks "a new era in the fight against antibiotic-resistant bacteria", adding that millions of people stand to benefit from this.
