Antibiotic-resistant bacteria with the potential to cause untreatable infections pose "a catastrophic threat" to the population, the chief medical officer for Britain warns in a report calling for urgent action worldwide.

If tough measures are not taken to restrict the use of antibiotics and no new ones are discovered, said Dame Sally Davies, "we will find ourselves in a health system not dissimilar to the early 19th century at some point".

While antibiotics are failing, new bacterial diseases are on the rise. Although the "superbugs" MRSA and C difficile have been reduced to low numbers in hospitals, there has been an alarming increase in other types of bacteria including new strains of E coli and Klebsiella, which causes pneumonia.

These so-called "gram negative" bacteria, which are found in the gut instead of on the skin, are highly dangerous to older and frailer people and few antibiotics remain effective against drug-resistant strains.
