investigation of the properties of naturally occurring antibacterial substances. Lysozyme‚ an antibacterial substance found in saliva and human tears‚ was their original research‚ but their interest moved to substances now known as antibiotics. The work on penicillin (one of the first types of anti-biotics) was a result of their experiments. He had been awarded honorary degrees by seventeen universities and is a member or honorary member of many learned societies and academies in the field of medicine and biology

These are variables that are uncontrolled and make the animals unsuitable for scientific research. Even though penicillin has been proven to save many human lives it kills cats and guinea pigs.

Furthermore‚ animal testing nearly prevented the approval of valuable drugs such as penicillin and subsequent antibiotics‚ but it did not prevent the thalidomide disaster of the 50s and 60s. If animals are not useful predictors of important disease responses in humans it is unlikely they are useful as test subjects for the safety of human
