Although the "antibiotic era" dates from

notatum in 1928, not until 1940 could penicillin be produced in
a sufficiently pure form to treat humans.1 Ominously, a
lactamase (penicillinase) capable of inactivating penicillin was
described in the previous year. Over the next few decades the
production of new classes of antibiotics (derived from living
organisms) and antimicrobials (synthesised chemicals) increased
exponentially, and the burden of infection was lifted, especially in
developed countries. In recent years concern has increased that the
antibiotic era might be coming to an end
firstly, because the rate of
production of new agents has diminished greatly and, secondly, because
viruses, bacteria, fungi, protozoa, and parasites are showing great
ingenuity in devising mechanisms for circumventing the killing activity of such agents.
So great is the concern that several committees both in the
United Kingdom and elsewhere are examining different aspects of
