Penicillin, chloramphenicol.

like penicillin. (Laughter)

I am not allergic to penicillin.

Penicillin has contributed much to the welfare of mankind.

To whom do we owe the discovery of penicillin?

To whom do we owe the discovery of penicillin?

I am allergic to aspirin, penicillin, and sulfa drugs.

And we stored penicillin at 60 degrees C, so 140 degrees Fahrenheit, for two months without loss of efficacy of the penicillin.

So we've made a silk card with penicillin in it.

They get soap, hygiene, education, vaccination, penicillin and then family planning.

It's not roads, or penicillin, or factory tires it's the new stuff.

I think actually it might be able to save more lives than penicillin.

You could have made it in the 1920s you wouldn't have had penicillin.

And I gave him a prescription for penicillin and sent him on his way.

Here's a list of the things he's been shot with sulfamerazine, sulfadiazine, penicillin, separadone, vitamin K.

So if we put you in the category of you've got syphilis, we can give you penicillin.

That was how quickly penicillin was produced and became one of the greatest medical advances of all time.

Some bacteria figured out how to stay away from penicillin, and it went around sort of creating its little DNA information with other bacteria, and now we have a lot of bacteria that are resistant to penicillin, because bacteria communicate.

The discovery that had led to penicillin, for example, is one of the most fortunate accidents of all time.

Penicillin was discovered in 1928, but even by 1940, no commercially and medically useful quantities of it were being produced.

And not only did they do it, but within two years, they scaled up penicillin from preparation in one liter flasks to 10,000 gallon vats.

Whereas China could get healthy much earlier, because they applied the knowledge of education, nutrition, and then also benefits of penicillin and vaccines and family planning.

And he wrote this book to explain, among other things, what it was like to be a medical intern at the Boston City Hospital in the pre penicillin year of 1937.

And my favorite example of that which is not really widely known as a technological miracle, but it may be one of the greatest of all times, was the scaling up of penicillin in the Second World War.

In fact, the whole reason why I'm using this as an example is because this is a fairly simple example as opposed to kind of explaining the metabolism of a certain type of bacteria and how that might change and how it might become immune to penicillin or whatever else.
