A new type of antibiotic developed from soil culture could solve one of the most pressing medical problems of the modern age: antibiotic resistance. New drugs could save millions of lives lost to killer microbes.
A paper in the journal Nature details how the new antibiotic, dubbed teixobactin, proved completely effective at healing mice infected with the most common drug-resistant forms of super-bug MRSA and tuberculosis. What’s more, it could take a long while for bacteria to become resistant – which is particularly useful as pathogens around the world build up resistance to treatments.
“The need for new antibiotics is acute due to the global problem of pathogen drug resistance.Teixobactin’s dual mode of action and binding to non-peptidic regions suggest that resistance will be very difficult to develop,” said Dr Kim Lewis, co-founder of biotech firm NovoBiotic, which helped develop the drug.
For years now, doctors have been warning about the problems coming down the line from antibiotic resistance. The overprescription of the drugs, and their wholesale use in the livestock farming business, has led to the evolution of illnesses that laugh in the face of even the most complex antibiotic compounds.
Last month a UK government study [PDF] on the subject estimated that antibiotic-resistant infections kill 700,000 people each year worldwide, and that without new forms of the medicine, that could rise to 10 million a year by 2050.
