1 gen 1940 anni - Testing Pencillin

Descrizione:

Chain began his trials. He requested that two strept-infected mice be injected with a sample of the penicillin he and his partner had extracted. Though the injection represented a far higher dosage than that administered in Fleming’s similar experiment, the mice survived apparently unharmed; the more concentrated penicillin had passed its first toxicity test. Florey then directed the antibacterial properties of penicillin in mice to be tested, this is something Fleming didn't do.
