Discovery of penicillin.

This short recording is an extract of a talk by Sir Alexander Fleming entitled 'Discovery of Penicillin', a BBC recording for Science Notebook, 28 August, 1945. Fleming talks about penicillin and the hopes to be found from other moulds in the future. He also warns, prophetically, about antibiotic resistance and how the wrong dosage (and usage) of penicillin could lead to 'educated microbes' - an outcome of antibiotic use which is all too familiar over half a century later. 1 segment.
